qmake

问题 I'm using QT 5.9.1 working on Mac OS. My project is mobile App with C++ logic and QML UI Layer. All QML files are included into qml.qrc file, so in my .pro file I have RESOURCES += qml.qrc Inside qml.qrc there is a list of all resource files I use in Project, such as pictures, icons and QML files, in QT Creator it's displayed OK: As you can see some QML files are located in ROOT path of qml.qrc when other files are in subfolders , e.g. "qrc:/Elements/". So problem is that whenether I make

问题 Is there a way to use the .pro file in Qt to call another Makefile? For example, in a makefile, you could use: make -f /other/path/Makefile Is there anything like using the pro file for Qt? 回答1: Something like this should work: QMAKE_EXTRA_TARGETS += other PRE_TARGETDEPS += other other.commands = make -f /other/path/Makefile this will cause make -f /other/path/Makefile to be called as part of the make process, and will also give you the ability to type make other to just run that command. 来源：

问题 Greetings, I've got a .pro file that looks like: TEMPLATE = subdirs SUBDIRS = foo bar I want to set a variable, or define, or something in my subdirs .pro file that can be read in both the foo and bar .pro files. I've tried to set an environment variable with: export TEST=something but that does not work, message($$(TEST)) always shows nothing (like TEST is unset). 回答1: Another option is to place the common variables in a file called ".qmake.cache" stored in the root dir of the project. This

问题 I have a Linux Qt program. I'd like it to preferentially use the (dynamic) Qt libraries in the executable's directory if they exist, otherwise use the system's Qt libs. RPATH to the rescue. I add this line to the qmake 's .pro file: QMAKE_LFLAGS += '-Wl,-rpath,\'\$$ORIGIN\'' and looking at the resulting executable with readelf I see: 0x000000000000000f (RPATH) Library rpath: [$ORIGIN:/usr/local/Trolltech/Qt-5.2.0/lib] 0x000000000000001d (RUNPATH) Library runpath: [$ORIGIN:/usr/local/Trolltech

问题 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 ? 回答1: Update: See @milanw's answer below. This is now

问题 pkg-config doesn't come stantdard with Mac OSX (10.8.4). For my Qt project I wanted to use pkg-config to link in protocol-buffer, so that it would be portable. The very point of choosing Qt was to have a portable app in the first place. However, qmake would not let me use pkg-config. Linking libraries to a QT project using pkg-config output gives a simple recipe that should work. But it doesn't with CONFIG += link_pkgconfig PKGCONFIG += protobuf I'm getting the error Project ERROR: Package

问题 I have a Qt-project that builds a dll/shared-library and another Qt-project that tests the library. Is there any good way to have qmake copy the dll to the output-folder of the test-project? 回答1: Add this to your pro file: target.path = ../testProject/$$TARGET INSTALLS += target 回答2: # Copy the dynamic library. win32 { QMAKE_PRE_LINK=copy /Y lib\qextserialport\src\build\qextserialportd.dll debug\ & copy /Y lib\qextserialport\src\build\qextserialport.dll release\ } else { # TODO: Unices } This

问题 I've got a problem with include in a qmake project. In my .pro file I've got: INCLUDEPATH += "C:\OpenCV\build\include" and in my cpp : #include <opencv\cv.h> The compiler indicates an error: Cannot open include file: 'opencv\cv.h': No such file or directory but if I write this in my cpp: #include "C:\OpenCV\build\include\opencv\cv.h" it works! I build the project from within Qt Creator. What am I doing wrong? 回答1: You have to run qmake(build->run qmake) to validate changes in the pro file. Qt
