qmake

Is there a way to build Qt in "Release with Debug info" mode ? My application crashes only in "release" mode (works fine in Debug mode) and seems the issue comes from Qt (may be a bug in Qt).So I want to see the debug info of Qt. Qt docs has "debug" , "release" but not "release with debug" mode. [Upate] My application works fine with Mingw 32bit Release/Debug and VSC++ Compiler 64bit Debug. Only crashes on VSC++ 64Bit Release Any tips ? Update: See @milanw's answer below. This is now supported directly in qmake We use qmake to generate vcproj files to build Qt. I wrote a python script (but sed

I added version.target = version.h version.commands = bash generate-version.sh QMAKE_EXTRA_TARGETS += version PRE_TARGETDEPS += version.h to the project, but it attempts to run "generate-version.sh" in destination directory: make: Leaving directory `.../qqq-build-desktop' make: Entering directory `.../qqq-build-desktop' Makefile:236: warning: overriding commands for target `version.h' Makefile:233: warning: ignoring old commands for target `version.h' bash generate-version.sh bash: generate-version.sh: No such file or directory make: Leaving directory `.../qqq-build-desktop' There is $$DESTDIR

I have a .pro file on my project, but now I want to port it to a CMakeLists.txt file, how can I do this ?

I have a Qt project that uses qmake. To improve clarity and readability, I'd like to keep the source files build system generated files (such as object files) separate. So my first step was putting the source files into a src/ sub directory: myproject/ myproject.pro src/ main.cpp MainWindow.ui ... That way I separated the source files from the build system (*.pro). However, when I then run qmake followed by make , the generated files (object files, etc) are placed into the main project folder: myproject/ myproject.pro Makefile main.o ui_MainWindow.h ... src/ main.cpp MainWindow.ui ... Well, at

I have multiple versions of Qt installed, and I need to compile my project with all of them. Using a pro file, I could not find in the documentation how to do a conditional compilation. Ideally, this is what I would like to do: QT_VERSION = 5 # this can be 4, set manually if(QT_VERSION == 5) { QT += widgets } if(QT_VERSION == 4) { QT += gui } Naturally, the if() command does not exist in pro files. Is there a better way to do the same thing? Nemanja Boric You can use conditional functions and scopes here: QT_VERSION = 5 # this can be 4, set manually equals(QT_VERSION, 5){ QT += widgets }

I need to generate a 32 bits version of my application however I am compiling on a 64 bits OS. I'm looking for a way to make QMake to generate both 32 and 64 bits versions of my application. If this is not possible I would like to know how to switch to 32 bits. I would also like to avoid having to mess with the generated makefile. Use a construction something like: CONFIG += 32bit CONFIG(32bit) { TARGET = 32bit_binary QMAKE_CXXFLAGS += -m32 LIBS += -L<path to 32bit libraries> } CONFIG(64bit) { TARGET = 64bit_binary } in your .pro file. Then you only need to change one line to recompile for the
