make will not create certain modules because of a trailing backslash

[rudi]

Using GNU Make 3.81 r2 certain libraries cannot be built using the makefiles created by QMAKE. Error message looks like this:

E:\Qt\4.5.1-os2-beta1\src\testlib>make -f Makefile.Debug
make: *** No rule to make target `..\..\lib\QtTestd4.lib\',
needed by `..\..\lib\QtTestd4.dll'.  Stop.

As you can see, there is a trailing backslash appended to the target. The problem seems to be known as it is mentioned in:

qmake\generators\win32\winmakefile.cpp, line 638

My fix was to change winmakefile.cpp and gnumake.cpp to add an empty comment to the following items:

TARGET
DESTDIR_TARGET
DEF_FILE
RES_FILE
RC_FILE
TARGET_IMPLIB

Not sure if all of them are neccessary, but here it was required to get the stuff built.

with which svn rev did you get the above error? with svn rev >= 153 or with the original beta1?

[Dmitry A. Kuminov]

I suppose you tried the .zip file. The problem you described was fixed in SVN, r153. So if you take the latest SVN tree it will build fine. I will reupload a new .zip soon.

[rudi]

Yes, I tried the ZIP file. May give the SVN version a shot this weekend...

[Dmitry A. Kuminov]

OK, please. Feel free to reopen this ticket if the problem still exists on your side.

[rudi]

With the SVN version the problem is gone. Thx. BTW, was it a carriage return/line feed thing ?

[Dmitry A. Kuminov]

Great.

What carriage return/line feed thing?

Hi,
I build today a certain apps, but it stops here with:

emxomfar r release\database.lib @release\OBJECTS.database.Release.rsp

I thought it's the same error like this one.
I use beta2

[Dmitry A. Kuminov]

It clearly says:

make.exe[3]: *** No rule to make target ..\database\libdatabase.a'

My guess is that the gui.pro file refers to the library in a non-portable way (something like LIBS += -llibdatabase.a) instead of just LIBS += -ldatabase...

Yes, according to ​http://chessx.svn.sourceforge.net/viewvc/chessx/trunk/src/gui/gui.pro?view=markup, it's the case. So, isn't our bug.

Their problem is that they want PRE_TARGETDEPS (to get '* No rule to make target...' from makr instead of 'Cannot find library...' from the linker if the build order is broken) and PRE_TARGETDEPS needs a full path which differs depending on the platform.

Just craete an os2 section similar to win32 (don't forget to replace .a with .lib).
