How to port a qmake project to cmake
After sacrificing some of the modularity and complexity of the Tool.pro file above, I was able to build the project using cmake. Here's the CMakeLists.txt file that I wrote: project( slugs ) cmake_minimum_required( VERSION 2.6 ) add_definitions ( -Wall ) add_definitions ( -D USE_CUDD ) set ( BDDFLAGS "-mtune=native -malign-double...
Adding SIP as a compiler for qmake
qt,makefile,pyqt,qmake,python-sip
The issue was occurring due to make using string matching to link dependencies to targets, rather than detecting if a target/dependency is a path and doing any relevant conversion. In my case, it was because the library dependency for my generated source file was listed as a relative path (../../Syren2/core/sipOutput/sipcoreSy_version.cpp),...
How to create re-usable libraries based on qmake?

You can do a project like this : MyProject: project.pro App App.pro main.cpp lib1 lib1.pro lib1.pri lib1.h lib1.cpp lib2 lib2.pro lib2.pri lib2.h lib2.cpp project.pro TEMPLATE = subdirs CONFIG += ordered SUBDIRS += \ lib1 \ lib2 \ App App.pro QT += core QT -= gui include(../lib1/lib1.pri) include(../lib2/lib2.pri) TARGET = App...
Qmake get the target output file path
You don't have to specify target.files, target is a special case and it's predefined in qmake. http://qt-project.org/doc/qt-4.8/qmake-environment-reference.html#installs If you append a built-in install set to the INSTALLS variable and do not specify files or extra members, qmake will decide what needs to be copied for you. Currently, the only supported...
Qt include path being ignored?
$$PWD is the path of the .pro file being parsed at the time the variable is encountered. If your $$PWD is in an include file, you may want to use $$_PRO_FILE_PWD_ instead, as this points to path of the project file, not any of its includes. Your use of $$PWD...

Make c++ macro2 containt quoted body of macro1
When a C preprocessor macro is expanded, its parameters are expanded to their literal arguments, so s would be expanded to A when your QUOTE(s) taking argument A is expanded. Normally, after this expansion is complete, the expanded text is then scanned again to expand any macros embedded therein, so...

There are two approaches to address this problem. Not to check againt the initially empty directory docInstall.CONFIG += no_check_exist directory Since this directory will be created on the fly, I would personally opt for this.

Qt Creator: copy .exe output into a folder
On Windows you can use DLLDESTDIR variable which specifies where to copy the target dll or exe. Just add this to your .pro : CONFIG(release, debug|release): DLLDESTDIR += $$PWD/../exec On Linux you can use QMAKE_POST_LINK variable which contains the command to execute after linking the TARGET together. So it is...
qmake's write_file() and system() doesn't want to make a file
Huh! I found the solution and it may sounds like buy yourself some brain. I thought, that qmake is launched every time the project file is changed (output of message commands proved my thoughts), but it's not really the way things happen in Qt. I don't know how exactly, but...
Qmake Qt: Move Header file to build folder

How to share build step in Qt Creator
Try replacing the custom build steps with QMAKE_POST_LINK commands (QMAKE_POST_LINK Reference) They can be linked to a script that can be committed: win32 { QMAKE_POST_LINK = install/win/deploy } unix { QMAKE_POST_LINK = install/unix/deploy } To create pre-build steps, this is a nice example: Pre-pre-build commands with qmake....
QMAKE_EXTRA_COMPILERS output directory, msvc
Idea 1 MSVC places object files usually into a release/debug sub-directory of the build dir. The other compilers don't. Thus you just have to add release/ or debug/ between ${QMAKE_VAR_OBJECTS_DIR} and ${QMAKE_FILE_IN_BASE}, e.g. win32:CONFIG(release, debug|release): ExtraCompiler.output = ${QMAKE_VAR_OBJECTS_DIR}release/${QMAKE_FILE_IN_BASE}$${QMAKE_EXT_OBJ} else:win32:CONFIG(debug, debug|release): ExtraCompiler.output = ${QMAKE_VAR_OBJECTS_DIR}debug/${QMAKE_FILE_IN_BASE}$${QMAKE_EXT_OBJ} else: ExtraCompiler.output =...
Qmake configuration using Buildroot

Are you using Qt4 or Qt5 ? Your package/dummypgm/Config.in should have a depends on on one of them, and your dummypgm.mk should have a DUMMYPGM_DEPENDENCIES = qt or DUMMYPGM_DEPENDENCIES = qt5base. My intuition is that you are using Qt5. In this case, you shouldn't call $(QT_QMAKE), but $(QT5_QMAKE). Have a...

The offending line is this: PyType_Slot *slots; /* terminated by slot==0. */ The problem is that with this line, "slots" is a keyword by default in Qt. In order to use that variable name in other projects, you will need to use this in your project file: CONFIG += no_keywords...

Should it be called setText instead? void getX(const QString& string) { ui->textEdit->setText(string);...

How to write the qmake file for a test case? [duplicate]

I think those errors usually occur without Qt += webkit, but in this case that's not what's happening. That is correct, however the QtWebkit module was split into webkit and webkitwidgets in Qt...

Compiling Qt3D under Windows 7

Qt $$[…] - configuration option that were set when Qt was built
QT_INSTALL_PLUGINS is one of the built-in properties of qmake. The manual of qmake in Qt 4.8 talks about qmake's built-in properties but does not mention QT_INSTALL_PLUGINS specifically. The manual of qmake in Qt 5 shows a much longer list of built-in properties including QT_INSTALL_PLUGINS. If you take a look...
