问题 The PC I'm using has 4 cores so I wanna use all them while compiling, which I do by passing the -j4 option to the compiler. In Qt Creator I do that by adding an environment variable in the Build Environment panel, as shown in the images: MAKEFLAGS = -j4 The problem is that this setting doesn't persist across all projects in the PC I'm using, which will be cool. So I have to do that for each project at least once. I think this is stored in the .pro.user file, since every time .pro.user gets

问题 I've tried this condition, but it doesn't work. How to check for MSVC 2013? win32-msvc2013*{ QMAKE_CXXFLAGS += /FS } I'm using Qt 5.3 Beta which has msvc-2013 mkspec. 回答1: Sorry for necroposting, but there seems no googleable solution. Seems I found one. There is vcvars.bat file, which is used for setting correct environment variables for VC. QtCreator, for example, use it while setting Tools -> Options -> Build & Run -> Compilers. Also it is used for MSVC Command Promt. Let`s check

问题 One can find a lot of examples where QMAKE_LIBDIR is used to specify additional library directories. The Qt manual says: QMAKE_LIBDIR Specifies a list of system library paths. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. Up to now I always used "unix: -L$$(LIB_DIR) -l" or similar whenever I wanted to use an external library in one of my projects and didn't want to use the library wizard. Can I conclude that specifying a path via -L is

问题 I want use std::nearbyint in android gcc but then ndk complains that std::nearbyint is not a member of std. I have the cmath header included in my code & the same builds well for OSX. Is there a workaround for this ? Is possible to write my own version of std::nearbyint ? I am using NDK14b on android 回答1: This is part of https://github.com/android-ndk/ndk/issues/82. GNU's libstdc++ is overly broad with their feature guards. We're working on stabilizing the NDK's solution for libc++ so we can

问题 I try to build an QT project using qmake. For this I need the boost library. LIBS += -L/usr/lib/ \ -lboost_system \ -lboost_filesystem But after running qmake, these libraries are not added to the makefile: LIBS = $(SUBLIBS) -L/usr/X11R6/lib64 -lQt5MultimediaWidgets -L/build/buildd/qtmultimedia-opensource-src-5.0.1/lib -L/usr/lib/x86_64-linux-gnu -L/usr/lib/x86_64-linux-gnu/x86_64-linux-gnu -lQt5OpenGL -lQt5Multimedia -lpulse -lQt5Widgets -lQt5Network -lQt5Gui -lQt5Core -lGL -lpthread As

问题 My .pro file looks like this: QT += core gui widgets SOURCES += a.cpp HEADERS += a.h FORMS += a.ui #Locally compiled Qt framework.

问题 I am using libqtermwidget in one of my Qt applications. It so happens that in version 0.8.0 of the library, some new features have been introduced, which are absent in 0.6.0 version. Since libqtermwidget does not provide any version macros, I would like to use pkg-config to check its version, something like this, in qmake: # i would like a functionality like this if pkg-config --version qtermwidget5 < 0.8.0 DEFINES += OLD_QTERMWIDGET This of course could be used inside the cpp file: #ifndef
