force 32 bits program in .pro file

force 32 bits program in .pro file - c++

I know I can run qmake from the command line and use:
-spec linux-g++-32
From the .pro file i've tried to add alternatively "-m32" or "-32" to "CFLAGS" or "QMAKE_CXXFLAGS" but it does not work.
CFLAGS += -m32
QMAKE_CXXFLAGS += -m32
What shall I do then ?
EDIT:
this is what is produced with the above flag...

Ok, here is the point:
the diff between the generated makefile ( through QtCreator ) and the one generated by my command line is:
INCPATH = -I/Soft/fox_dev/Qt-4.7.4/mkspecs/linux-g++-32 -I. -I/Soft/fox_dev/Qt-4.7.4/include/QtCore -I/Soft/fox_dev/Qt-4.7.4/include/QtXml -I/Soft/fox_dev/Qt-4.7.4/include/QtXmlPatterns -I/Soft/fox_dev/Qt-4.7.4/include -I../../../fx/libfx -I../../../fx/MQLib -I/Soft/fox_dev/boost/boost_1_54_0 -I/Soft/fox_dev/xerces-c-3.1.1-x86-linux-gcc-3.4/include -I/Soft/fox_dev/xerces-c-3.1.1-x86-linux-gcc-3.4/include -I.
Vs
INCPATH = -I/Soft/fox_dev/Qt-4.7.4/mkspecs/linux-g++ -I../fxa_march -I/Soft/fox_dev/Qt-4.7.4/include/QtCore -I/Soft/fox_dev/Qt-4.7.4/include/QtXml -I/Soft/fox_dev/Qt-4.7.4/include/QtXmlPatterns -I/Soft/fox_dev/Qt-4.7.4/include -I../../../fx/libfx -I../../../fx/MQLib -I/Soft/fox_dev/boost/boost_1_54_0 -I/Soft/fox_dev/xerces-c-3.1.1-x86-linux-gcc-3.4/include -I/Soft/fox_dev/xerces-c-3.1.1-x86-linux-gcc-3.4/include -I. -I../fxa_march -I.
however one can go to "Project-> Build Settings -> [choose configuration to modify] -> And edit the "Qmake step" with additionnal argument:
-spec linux-g++-32
you will also need to add in the .pro file either of:
CFLAGS += -m32
QMAKE_CXXFLAGS += -m32

In .pro file, try writting all commands inside a scope prefixed by win32
win32 {
SOURCES += paintwidget_win.cpp
# ...
}
Commands inside the scope will be run only if the win32 variable is set.

i did not try to create make file using qmake because of special library that i need in my own project, So i decided to write my own makefile, and this is the only class(testmain.cpp) in my source code that i use QT library in it,thi is testmain.cpp:
#include <QtWidgets>
int main(int argc, char **argv)
{
QApplication app(argc, argv);
QWidget qWin;
QGridLayout qGrid;
qGrid.addWidget(new QLabel("UTF-8:"), 1, 0);
QByteArray string = "شهاب حسینی";
QTextCodec *codec = QTextCodec::codecForName("UTF-8");
QString encodedString = codec->toUnicode(string);
qGrid.addWidget(new QLabel(encodedString), 1, 1);
qWin.setLayout(&qGrid);
qWin.show();
return app.exec();
}
but when I try to make my project ,executable test will not produce and i face with this errors which part of my make file is wrong ?

C++ Link Failure - ld: cannot find [makefile] [gcc/cygwin]

I am trying to create a system of makefiles to build my whole project. I am using cygwin and gcc compiler. I am running into a linking error on shared libraries that I cannot figure out.
I am concerned with ld: cannot find -lbase and ld: cannot find -lsimsimA429.
These files were clearly built. I even did a directory listing as part of the build command to show that they exist.
-rwxr-xr-x+ 1 user group 116832 Mar 25 10:09 /cygdrive/d/myProj/lib/libbase.so
-rwxr-xr-x+ 1 user group 75972 Mar 25 10:09 /cygdrive/d/myProj/lib/libsimsima429.so
and the link command also shows that I am including the correct link directory
g++ -shared -L/cygdrive/d/myProj/lib -lpthread -lrt -lbase -lsimsimA429 ...
What am I doing wrong to incur this error?
Also, I am relatively new to writing makefiles. If you have any comments about how I could improve them, I would kindly appreciate a few comments.
Full makefiles and output are listed below...

Cygwin shared libraries are *.dll files, not lib*.so files. I suppose your linker is struggling to find base.dll and simsimA429.dll.

Qt - statically compiled exe refers shared lib

My static compilation in Qt worked fine upto this week. I reinstalled the qt, and recompiled the static version. The headache started after this. Now, even though I compiled using tatic version. The resulting exe requires the Qt libs. I checked the exe with "dependency Walker". It showed that the required dll's path are pointing towards the dynamic/shared libs path. Here are my settings
Environment:
QTDYNDIR : D:\tempinstallationfolder\Qt\dynamic
QTSTADIR : D:\tempinstallationfolder\Qt\static
Path : %QTDYNDIR%\bin;%QTDYNDIR%\qt\bin;%QTDYNDIR%\mingw\bin;
%QTSTADIR%\bin;%QTSTADIR%\qt\bin;%QTSTADIR%\mingw\bin;
I add the mingw,qt paths
Somehow it manages to follow the dynamic lib's path. I don't know where I made the mistake.
Can anybody help me in this issue?.
Note: I am using Windows platform - qt - 4.7.0 (qt - open source v2010.05)of static,dynamic to the Qt-Creater=>Tools=>Options=>Qt.
EDIT:
This one is from the compile output. There is no dynamic path directory mentioned in these.

The process "D:/TempInstallationFolder/Qt/static/mingw/bin/mingw32-make.exe" exited normally.
Note: Now only I made the fresh install for dynamic and static . Still it is capable to produce the same result.

Have you added this line to your projectname.pro file?
CONFIG += static
and made sure that in QtCreator-Projects-Build settings the 'Qt-version' points to your static build?

I am not sure that this is the correct answer. I made the following changes. I am not sure which one corrected my problem.
1)It seems there must be a environment variable called as QTDIR which points to the dynamic installation dir.
2)I compiled the qt libs for static build using "visual studio" rather than "mingw".
After these steps I added the absolute paths of static and dynamic (qt-bin,lib,minwg-bin,lib) to the path.
Now, my things are working fine. I didn't vote it as a correct answer. Thereby some one can give the exact answer.

Engine Matlab issues

I am triyng to implement Matlab in a c++ program. http://www.cl.cam.ac.uk/~sjeh3/wii/
The application is using gtk a wii mote lib and the Matlab Camera Calibration Toolbox (http://www.vision.caltech.edu/bouguetj/calib_doc/ ). it works perfectly.
I want to use matlab ploting tools to build a graphic provided by the application. But i am having issues building the app with matlab engine .
In the main.cpp i just added the code from the matlab example engdemo.cpp in the main function and included engine.h and mex.h.
Even with the examples like engdemo.cpp i always have this error :
mex: link of ' "...mexa64"' failed.
here are the console views:

I forgot to say that i wanted to use Matlab engine and not my c++ application in matlab. maybe it wasn't so clear. I don't think the program will work as a mex-file.
Sincerely,
Hugo

If found my issue. i was compiling my application using mexopts.sh conf and not engopts.sh
After the succeful compilation i had the Error Can't start Matlab engine. i just apt-get install csh. and it work.

Your linux build command is broken. the compiler is missing some paths to some library.
