API_FPU_CW_Wrappers.h errors

[dmacias]

I am testing Harbour (www.harbour-project.org) hbqt contrib with Qt451GA for OS/2, using os2gcc442 in eCS pre-2.0

I installed Qt451GA using .wpi files from Netlabs

Using "Qt4 Command Prompt", setting os2gcc442 environment and Harbour environment as usual

In first try to build Harbour-hbqt it fail with this error:

---

E:\ecs\system\qt4\include/QtCore/qt_os2.h:59:33: error:
API_FPU_CW_Wrappers.h: No such file or directory

---

Searching for API_FPU_CW_Wrappers.h it does not exist anywhere in e:\ecs\system\qt4\include\ directories

Looking for API_FPU_CW_Wrappers.h it exist in:

E:\ecs\system\qt4\mkspecs\os2-g++
E:\ecs\system\qt4\mkspecs\default

with same date and content:

17/12/09 3:22a 145,271 0 a--- API_FPU_CW_Wrappers.h

Copying API_FPU_CW_Wrappers.h to e:\ecs\system\qt4\include\ and trying again build of Harbour-hbqt many errors are raised from
API_FPU_CW_Wrappers.h and then GPF with "Killed by SIGSEGV"

So something are wrong in API_FPU_CW_Wrappers.h reference, content and use under OS/2

Below are included build output log for
First try, API_FPU_CW_Wrappers.h missing:

Most errors may be due API_FPU_CW_Wrappers.h missing

Second try, with API_FPU_CW_Wrappers.h:

This Harbour-hbqt contrib are working in Windows, Linux, Mac, ...

[Dmitry A. Kuminov]

As far as I can see, the project doesn't use qmake. For this reason, the include path E:\ecs\system\qt4\mkspecs\default (or E:\ecs\system\qt4\mkspecs\os2-g++ which is the same in this case) is not passed to the compiler. Adding it to the list of include directories for the compier should fix the problem for you. Please try and report back.

For the second case, it's the wrong include order -- a typical problem for the OS/2 environment caused by the way the os2.h file (which is a central access point to the OS/2 APIs) is organized. In your case, it seems that os2.h is manually included from either hbqt_hbqmainwindow.cpp or hbqt_hbqmainwindow.h (or from another file they include) before Qt4 headers are included. Such an order is not supported and should not take place -- Qt includes must go first. Also, it's not clear why os2.h is included manually in a Qt source file in the first place: in theory, this should be never needed. If you give me more details on this, I will be able to suggest you the best solution.

P.S. SIGSEGV is probably due to too many errors (e.g. maybe a bug of the GCC4 port) and is not related to Qt4.

Thanks for your help
We use GNU make
Using:

set C_INCLUDE_PATH=E:\ecs\system\qt4\mkspecs\default;%C_INCLUDE_PATH%
set CPLUS_INCLUDE_PATH=E:\ecs\system\qt4\mkspecs\default;%CPLUS_INCLUDE_PATH%

then API_FPU_CW_Wrappers.h missing has gone, and we have a lot of errors due API_FPU_CW_Wrappers.h

os2.h is included in qt_os2.h before API_FPU_CW_Wrappers.h
hbqt_hbqmainwindow.cpp just call QMouseEvent of Qt4, which lead to rest of sequence of Qt4 files, including qt_os2.h, os2.h, API_FPU_CW_Wrappers.h:

I have not clear this case,
can you explain or suggest any other checks/tests ?

P.S. SIGSEGV is probably due to too many errors (e.g. maybe a bug of the GCC4 port) and is not related to Qt4.

Does not happen anymore. Checked with three or four re-builds

Of course, I know that os2.h is included in qt_os2.h :) I was asking you to check if os2.h is directly or indirectly included somewhere *before* any Qt header (i.e. in case of hbqt_hbqmainwindow.*, before QMouseEvent is included) -- frankly saying, this is the only reason that could cause these 'something was not declared in this scope' errors that comes to my mind so far.

To make it simpler to check, do the following command

gcc -I. -I../../../../../include -Zomf -Wall -W -O3 -DHB_LEGACY_TYPES_OFF -IE:\ecs\system\qt4\include -IE:\ecs\system\qt4\include/QtCore -IE:\ecs\system\qt4\include/QtGui -IE:\ecs\system\qt4\include/QtNetwork -DTCPV40HDRS -DHB_FM_STATISTICS_OFF -ohbqt_hbqmainwindow.o -E ../../../hbqt_hbqmainwindow.cpp >hbqt_hbqmainwindow.preprocessed.cpp

It will expand (due to the -E option instead of -c) all the includes, defines and so on and place the output to hbqt_hbqmainwindow.preprocessed.cpp. Then please attach hbqt_hbqmainwindow.preprocessed.cpp to this ticket.

[Dmitry A. Kuminov]

And BTW, is there any specific reason for -DTCPV40HDRS? This will cause gcc to use the outdated TCP stack (which is 16-bit AFAIR) instead of the more modern 32-bit stack used by Qt. I heard that these stacks are not compatible and won't work together (though I don't know all the details).

Sorry, all of this is a mistery for me :-)
I do not know C, C++, ...

It will expand (due to the -E option instead of -c) all the includes, defines and so on and place the output to hbqt_hbqmainwindow.preprocessed.cpp. Then please attach hbqt_hbqmainwindow.preprocessed.cpp to this ticket.

It was necessary to delete -ohbqt_hbqmainwindow.o, it result in 1.4 Mb file
hbqt_hbqmainwindow.preprocessed.zip file is attached

As hbqt build work fine with some files, fail with hbqt_hbqmainwindow.cpp and remain files to build, I skipped hbqt_hbqmainwindow.cpp and tried with remaining files (some of them)

Files which failed show some type of error (see below), so fixing problem with hbqt_hbqmainwindow.cpp may lead to fix of rest

And BTW, is there any specific reason for -DTCPV40HDRS? This will cause gcc to use the outdated TCP stack (which is 16-bit AFAIR) instead of the more modern 32-bit stack used by Qt. I heard that these stacks are not compatible and won't work together (though I don't know all the details).

In Harbour project Maurilio Longo is our OS/2 expert and he explained us years ago that we must build Harbour with -DTCPV40HDRS in order to be used in old OS/2 and new eCS
If this case may have problem with Qt I can inform it in Harbour project. Just tell me :-)

As I am Harbour for OS/2 releases builder, I am just following guidelines of experts

Harbour for OS/2 2.0.0 is public near two months ago and we have around 566 downloads of this release, our maximum historically
hbqt contrib was the "big absent" in OS/2 platform, so I am trying to include it soon

Thanks for your interest

if you look at your provided build log you see that os2.h gets included very fast at the beginning. and qt_os2.h comes a lot later. so this can't work of course.
i suggest that you include qt_os2.h at the beginning of the source.

[Dmitry A. Kuminov]

Just to clarify Silvan, os2.h is indeed included very early: from hbdefs.h which is included before <QtGui/QMouseEvent> through other hb* headers (hbapi.h -> hbvmpub.h).

So, my assumption was correct. Please make sure Qt headers are included before hb* ones in all sources -- there is no other way to make it work on OS/2 (*). Also note that it's not necessary to include qt_os2.h directly as suggested by Silvan unless you need to directly access OS/2 API from the Qt-based part of the code (which is non-portable and therefore should be avoided by all means).

(*) The thing with os2.h is that you have to specify what parts of the API you want before including it (using the #define INCL_xxx directives). If you do it once, all subsequent attempts to include os2.h again (probably with a different set of INCL_xxx defines) will be ignored by the compiler because os2.h contains a protection code that allows to include its contents only once per every compilation unit (.cpp file). Therefore, if your set of INCL_xxx doesn't drag in APIs needed by some other parties involved in the compilation process there is nothing these parties can do.

BTW, if you don't want to toss the Qt includes around in all sources, there is one alternative solution. Just add the following to hbdefs.h right before the line where os2.h is included:

#define OS2EMX_PLAIN_CHAR
#define INCL_BASE
#define INCL_PM

This will make sure that os2.h will drag in all the APIs it has so every party will be eventually happy.

Okay, I had a small discussion on this topic with other OS/2 people and this is what I found. The only benefit of the 16-bit stack (that is used by Innotek GCC/kLIBC when you use -DTCPV40HDRS) comparing to the 32-bit stack (used otherwise) that the former is available on Warp3 while the latter is not (32 bit is also not available on Warp4 by default but it is easily solvable by installing a free Fixpak on it). So unless you really want to support Warp3 you can completely drop this define.

Next, both stacks can be probably used in parallel within the same process (never checked that) but they will for sure not be able to exchange sockets.

And another important thing that Qt is bound to the 32-bit stack, so even if your application using two different stacks will eventually work, it will not load on a system with no 32-bit stack installed anyway (due to the Qt dependency). So keep that in mind.

Just to clarify Silvan, os2.h is indeed included very early: from hbdefs.h which is included before <QtGui/QMouseEvent> through other hb* headers (hbapi.h -> hbvmpub.h).

Checking hbdefs.h it set many values for different platforms/compilers supported by Harbour

So, my assumption was correct. Please make sure Qt headers are included before hb* ones in all sources -- there is no other way to make it work on OS/2 (*). Also note that it's not necessary to include qt_os2.h directly as suggested by Silvan unless you need to directly access OS/2 API from the Qt-based part of the code (which is non-portable and therefore should be avoided by all means).

Now the section for OS/2 in hbdefs.h is:

---

#elif defined( HB_OS_OS2 )

   /* With the exception of WORD, the IBM Visual Age C++ compiler has
      its own definitions of the Harbour types most of which conflict with the
      Harbour #undefs, due to typedef being the prevalent method of

      definitions that it is replacing have been defined using
      #define. Therefore, it is necessary to skip the Harbour
      definition section when using the IBMCPP compiiler, include
      the IBMCPP type definitions, and then add the definition for WORD

      NOTE: This only applies to the common types that most C compilers
            define. Any new types, particulary those that start with

and most of hbqt build error has gone :-)
You got the key

It build fine three of four libs:

17/02/10 2:30p 300,032 124 a--- hbqt.lib
17/02/10 3:44p 809,984 124 a--- hbqtcore.lib
17/02/10 3:51p 71,168 124 a--- hbqtnetwork.lib

and fail with hbqtgui

Note: this is a response of our hbqt developer:

---

I know nothing about OS2 and hence not in a position to comment.

One point which comes in mind is that Harbour is supporting Qt 4.5.3
and your experiments are centered around 4.5.1. There is likelyhood
that some of the methods may not be available in 4.5.1. But to be
doubly sure, can you some short log of errors ?

Mostly these errors are the results of wrong headers.

---

In order to go ahead to solve hbqtgui I was trying build discarding each file with error. hbqtgui have hundreds of .cpp and .prg files (more than 400) and fail with these eleven:

# QAbstractPrintDialog.cpp \
# QInputContext.cpp \
# QPageSetupDialog.cpp \
# QPlainTextEdit.cpp \
# QPrintDialog.cpp \
# QPrintEngine.cpp \
# QPrinter.cpp \
# QPrintPreviewDialog.cpp \
# QTextDocument.cpp \
# QTextEdit.cpp \
# QWidget.cpp \

Notes:
Note 1) Many files even without error show this group of warnings:
E:\ecs\system\qt4\include/QtGui/qmime.h:150: warning: unused parameter 'targetName'
E:\ecs\system\qt4\include/QtGui/qmime.h:150: warning: unused parameter 'supportedOps'

Note 2) Most errors seem to be related to printer/printing

Perhaps some component are missing, and solution are related

Note 3) Discarding files with errors, we have a big lib:

18/02/10 12:44a 2,792,960 124 a--- hbqtgui.lib

I am attaching hbqtgui_errors.zip containing error section for each one of discarded files

It mean that Warp 3 support is excluded in your Qt4 development ?

David Macias

[Dmitry A. Kuminov]

Okay, good. I would just change this part in hbdefs.h to the following:

   /* 28/03/2000 - maurilio.longo@libero.it
      The same holds true when using GCC under OS/2
   */
   /* xx/02/2010 - whoever@there.is
      Include all OS/2 API definitions to make sure other involved parties
      (such as Qt for OS/2) will get everything they want
   */
   #define OS2EMX_PLAIN_CHAR
   #define INCL_BASE
   #define INCL_PM
   #include <os2.h>
   #undef INT
   #undef UINT
   #define HB_DONT_DEFINE_BASIC_TYPES

A new bunch of the errors from the .zip is indeed due to the missing printing support and missing accessibility support in Qt 4.5.1 for OS/2. For printing, there are three things you can do:

1. Add #ifndef QT_NO_PRINTER / #endif around the parts in the source code that use printing classes (QAbstractPrintDialog, QPageSetupDialog etc.) This btw will let it build on all platforms that don't provide printing support for some reason, not only OS/2.

2. Wait until the next release of Qt for OS/2 (4.6.1) is available. It will include printer support.

3. Check out the Qt4 source trunk from this site (which is already 4.6.1) and build Qt yourself.

As of accessibility, we may also provide a dummy implementation in 4.6.1, but it's not there yet, so you will have to do #ifndef QT_NO_ACCESSIBILITY / #endif around the places that complain about missing accessibility methods.

The warnings in qmime.h are known you may ignore them for now.

[Dmitry A. Kuminov]

Replying to dmacias:

Yes. Neither Qt3 nor Qt4 officially supports Warp3. And there are no current plans to provide such support.

Do you have plan to do it ? If so then I can wait for changes before to try a checkout/build of Qt

As I can see this ticket can be closed as main problem is solved

In order to mantain communication I tried:

• qt-user()netlabs.org [read online]

and content is empty

• qt-dev()netlabs.org [read online]

"All ticket changes are automatically posted to this list"

and no one info of tickets appear here

So how can I mantain contact for further questions, in place of using tickets ?

In order to advance and check Harbour hbqt, hbxbp, hbide, ... before official 4.6.1 release, I tried to build Qt4 using current code:

• Checkout of svn.netlabs.org/repos/qt4/trunk
• Environment based in readme.os2, including CUPS, thread,...
• Set os2gcc442
• Set Qt4 set LIBRARY_PATH=e:\OS2\DLL;e:\MPTN\DLL;%LIBRARY_PATH% set PATH=E:\Qt4\bin;%PATH% set BEGINLIBPATH=E:\Qt4\bin;%BEGINLIBPATH%
• configure.cmd fail:

  [...]
  cd e:\qt4\src\svg && e:\qt4\bin\qmake.exe svg.pro -os2 -o Makefile
  cd e:\qt4\src\script && e:\qt4\bin\qmake.exe script.pro -os2 -o Makefile

  cd e:\qt4\src\declarative && e:\qt4\bin\qmake.exe declarative.pro -os2 -o Makefile
  Cannot find file: declarative.pro.
  make.exe: *** [sub-declarative-qmake_all] Error 2
  

• Changing in configure.cmd:

  /*DAVID:    if (G.CFG_DECLARATIVE == "auto")    then G.CFG_DECLARATIVE = "yes"  */
      if (G.CFG_DECLARATIVE == "auto")    then G.CFG_DECLARATIVE = "no"
  

then it complete configure.cmd

• Using "make release" fail:

  g++ -c @tmp\obj\release-shared\CXXFLAGS.uic.Release.rsp @tmp\obj\release-shared\
  DEFINES.uic.Release.rsp @tmp\obj\release-shared\INCPATH.uic.Release.rsp -o tmp\o

Re qt-dev()netlabs.org, something is broken somewhere so trac doesn't actually send commit reports to this mailing list. If you are interested in commits, you may subscribe to it via RSS here ​http://svn.netlabs.org/qt4/timeline (bottom of the page).

Regarding the failing build, r590 should fix the exact problem you faced (thanks for reporting!) however the trunk doesn't yet fully build yet (see #136).

The third build problem occurs to everyone else trying to build it :) It's due to the invalid environment. The details (and the fix) are here ​http://svn.netlabs.org/qt4/ticket/110#comment:11. Use gccenv.cmd attached to the ticket and the problem should go away.

please get r594, as r593 didn't fix it completely

Thanks,
I used r598 in fresh checkout and after 7 hours building Qt461 it complete entirely without problems ( make release )

Building Harbour-hbqt contrib with Qt461 show problems in only two files in place of eleven, which belong to hbgui.lib

# QInputContext.cpp \
# QWidget.cpp \

Skipping these two files, Harbour-(hbqt.lib, hbqtcore.lib, hbgui.lib, hbnetwork.lib) build entirely
Trying to build applications using hbqt* libs, as demoqt.prg, hbide project, both fails due missing mainly by QWidget symbols but other symbols too

I am attaching qt4_logs.zip file which contain:

• make_qt.log Entire output of Qt461 build As my build is in environment different than yours, log file can serve to check, confirm, maybe to know new/different errors/warnings Searching for "warning" string in file help to review content quickly
• hbqt.log Output of Harbour-hbqt contrib build. Content are errors processing: # QInputContext.cpp \ # QWidget.cpp \ In few words, this is what is missing in Qt461 in order to achieve hbqt build in Harbour for OS/2
• demoqt.log, hbide.log Both are applications which need hbqt* libs and due missings in Qt461 no one application can be completed

Question: QInputContext, QWidget missings are related to planned QAccessible, or are additional missings ?
("Yes, we decided to provide the dummy QAccessible implementation in 4.6.1")

Thanks again for your help and I hope these tests help to mature Qt4 for OS/2, and obviously to put to work hbqt contrib in Harbour for OS/2

So I used:

QWidget.cpp
===========
/*DAVID:
HB_FUNC( QT_QWIDGET_ACCESSIBLEDESCRIPTION )
{
   hb_retc( hbqt_par_QWidget( 1 )->accessibleDescription().toAscii().data() );
}
*/
/*DAVID:
HB_FUNC( QT_QWIDGET_ACCESSIBLENAME )
{
   hb_retc( hbqt_par_QWidget( 1 )->accessibleName().toAscii().data() );
}
*/
/*DAVID:
HB_FUNC( QT_QWIDGET_SETACCESSIBLEDESCRIPTION )
{
   hbqt_par_QWidget( 1 )->setAccessibleDescription( QWidget::tr( hb_parc( 2 ) ) );
}
*/
/*DAVID:
HB_FUNC( QT_QWIDGET_SETACCESSIBLENAME )
{
   hbqt_par_QWidget( 1 )->setAccessibleName( QWidget::tr( hb_parc( 2 ) ) );
}
*/


TQWidget.prg
===========
//DAVID:   METHOD  accessibleDescription()
//DAVID:   METHOD  accessibleName()
//DAVID:   METHOD  setAccessibleDescription( cDescription )
//DAVID:   METHOD  setAccessibleName( cName )
/*DAVID:
METHOD QWidget:accessibleDescription()
   RETURN Qt_QWidget_accessibleDescription( ::pPtr )
*/

/*DAVID:
METHOD QWidget:accessibleName()
   RETURN Qt_QWidget_accessibleName( ::pPtr )
*/
/*DAVID:
METHOD QWidget:setAccessibleDescription( cDescription )
   RETURN Qt_QWidget_setAccessibleDescription( ::pPtr, cDescription )
*/

/*DAVID:
METHOD QWidget:setAccessibleName( cName )
   RETURN Qt_QWidget_setAccessibleName( ::pPtr, cName )
*/


and hbqtgui.lib build entirely


>link demos. Those must then link properly.

>If all goes fine, I will drop QInputContext alltogether.

>Without above exercise, it is difficult to isolate other matters.
>Logs of demos are useless as QWidget is not linked and all other

So you can:
- drop QInputContext alltogether.
- Guard *Accessible* methods for OS/2 and 
   #ifndef QT_NO_ACCESSIBILITY / #endif 
 while "dummy QAccessible implementation in 4.6.1" can be completed


Trying to use hbqt* libs with samples/projects:

So we have our firsts Harbour+os2gcc442+hbqt+qt461 applications running, but with failures still

We are advancing :-)

Okay, good to hear that there is some progress.

What about crashes you get, I would recommend you to build the debug vesion of Qt and run your application from under a debugger to get the call stack at a time when it crashes. If you then post the call stack, I will be able to look at the problem.

And, please, use the the qt-dev mailing list for further discussion on this topic. This ticket is not the right place for it.
