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, ...

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
Are more than 600 lines in build output
Most of them are of type:

'somevalue' was not declared in this scope

After long section of API_FPU_CW_Wrappers.h errors, begin a new section with qmime.h errors

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

[Dmitry A. Kuminov]

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).
