qmake
qmake: Test for current spec.
I would like to detect whether qmake is currently building using MingW (win32-gcc) or Visual Studio (win32-msvc200X). At the moment I am using the following construct: windows{ contains(QMAKE_CC, gcc){ # MingW } contains(QMAKE_CC, cl){ # Visual Studio } } This does not seem particularly robust. Is ther...
How to generate a single translation file for a large Qt project?
I have a large project with one qmake project file defining all project components using a 'subdirs' template. Currently I define translation files in the qmake files of each sub-project. This results in separate translation files for each sub-project, which quickly becomes too cumbersome to maintain. How do I get lupdate to produce a s...
Qt qmake - how to stop it adding rules to delete the target
I am trying to add a unit test to a group of other tests. All the tests are in their own subdirectories, each with it's own .pro file and the .cpp file which contains the tests themselves. Running qmake in one of the subdirectories creates a Makefile, and then running make runs the compiler to make the TARGET. The tests are actually run ...
qmake rules for generated code
I realized my earlier question was a little confused about the rules and dependencies. The following .pro file generates a makefile which works correctly IF the source files in the directory 'generated' exist at the time qmake runs. idl.target = generated/qmtest.h idl.commands = code_generator idl.config = no_link idl.depends = $...

Building multiple targets in Qt / Qmake
How could I specify multiple targets with different configurations in Qt? Is there a way to do it in one .pro file? For example, I would want to build the following 2 .pro files (without having to manually change the .pro file each time): targetA: QT += network TEMPLATE = app SOURCES += main.cpp \ mainwindow.cpp HEADERS += mainwin...

Im using Qmake to build a shared library on Ubuntu 9.10 This shared library (A) has a dependency on another shared library (B). project B has been successfully built. in the .pro file for project A, my LIBS variable looks like this: LIBS += -L../datelib/bin -llibdatelib_release.so.1.0.0 (I used the full shlib name because the libra...
bulding with qmake on Linux - how to prevent qmake from linking to QtCore and QtGui
I have a shared library (with no QT dependency) [library B] that links to another shared library (with no QT dependence as well) [library A]. I am using Qmake and QT Creator 1.3. The problem is that when I build library B and run ldd on the executable, it is being linked to QtCore and QtGui, both of which are pulling in lots of unrequir...
How to get qmake to generate "project dependencies" in a Visual Studio .sln project
I have a qmake build of a few libraries and an app which depends on them. Using the subdirs template I'm able to get qmake to output a .sln file which works almost to my liking in VC2008. Though I've specified the dependencies between the targets in every way I've seen described, I end up with no "project dependencies" in the .sln file...

How to specify different Debug/Release output directories in QMake .pro file
I have a Qt project and I would like to output compilation files outside the source tree. I currently have the following directory structure: / |_/build |_/mylib |_/include |_/src |_/resources Depending on the configuration (debug/release), I will like to output the resulting files inside the build directory under build/debug o...
How to link as .so instead of .dylib on OSX 10.6 using qmake
Hey everyone, I am trying to use SWIG to wrap some C++ code for the use with Python. As described here it seems to be necessary to link my C++ code against an .so file, not a .dylib file. The thread suggests to use libtool in combination with the -module flag to link, but I am using qmake and need more precise instructions on how I do t...

I've upgraded to Qt 4.6 on my Mac (OS 10.5). When I go to a project directory and run: qmake -project Qt returns this warning (although it doesn't say it's a warning, I assume it is since the .pro file gets created anyway): QFileInfo::absolutePath: Constructed with empty filename I did a completely new install thinking that the "up...
Shared variables in multi directory qmake
I have multiple qmake .pro files which are called from a root .pro file with a subdirs template. What is the best way to change a setting for the whole build system (eg. release to debug). Currently I can only do this by changing each sub .pro file, or using an external script to change each .pro file. I was hoping there was a way to ...
