问题 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?

问题 How to read file content into a variable in qmake project file? For example, I'd like to have the contents of KEY read from a file and pass it to the compiler: DEFINES += KEY=**some magic and filename here** 回答1: On all platforms, there's a built-in replace function $$cat : # set a qmake variable KEY = "$$cat(/path/to/the/file)" # propagate the variable to C/C++ DEFINES += "KEY=\"$$KEY\"" The effect of this line is the same as if you added the following line at the beginning of every

问题 I am using openCV 2.4.6.1 in Qt 5.2 on OSX.

问题 I'm trying to compile something from github: https://github.com/com2m/anki-overdrive-goes-iot/ When Running Qmake everthings seems fine, but whe in run make i get the follwoing error: g++ -c -pipe -g -std=gnu++11 -Wall -W -D_REENTRANT -fPIC -DQT_BLUETOOTH_LIB -DQT_CORE_LIB -I. -isystem /usr/include -isystem /usr/include/x86_64-linux-gnu/qt5 -isystem /usr/include/x86_64-linux-gnu/qt5/QtBluetooth -isystem /usr/include/x86_64-linux-gnu/qt5/QtCore -I. -I/usr/lib/x86_64-linux-gnu/qt5/mkspecs/linux

问题 I've got a question about signals and slots. In my app, I want to connect a signal from one object to a textEdit in a dialog window. My signal emits a QString ; if I violate encapsulation (by making the UI public instead of private) and connect the signal directly to the textEdit it works. But I feel that it's not the right way. If I make something like the following: connect(m_osgWidget->picker.get(), SIGNAL(setX(QString)), m_addAgentDlg, SLOT(getX(QString))); where: void getX(QString) {

问题 I'm trying to use QScintilla on MacOS X, I added LIBS += -lqscintilla2 in the .pro, with this quite simple code: #include <QApplication> #include <Qsci/qsciscintilla.h> int main(int argc, char* argv[]) { QApplication app(argc, argv); QsciScintilla *qscintilla = new QsciScintilla; qscintilla->show(); return app.exec(); } (Im using QtCreator btw) Here is the error : dyld: Library not loaded: libqscintilla2.5.dylib Referenced from: /Users/lubethan/cxx-proj/NightPad/NightPad.app/Contents/MacOS

问题 I'm going mad on this stupid problem. I've a tree like this: src |--- sources |--- one.cpp |--- two.cpp |--- sources.pro |--- headers |--- one.h |--- two.hpp |--- headers.pro |--- src.pro I tried EVERYTHING to make it look in both the folders, but somehow I can't get it working. I don't know much about QMake, but I tought it was easy. And I was wrong. So actually I ended up having the src.pro file in this way: QT += dbus CONFIG += warn_on DEFINES = QT_FATAL_WARNINGS QT_NO_DEBUG_OUTPUT devel {

问题 I have the shared library project with structure like this: library.pro: TEMPLATE = subdirs CONFIG += ordered SUBDIRS += libs plugins test_programs ... QT += concurrent ... # Those files contains pure interfaces (C++ abstract classes) # with no implementation, and some helper classes with inline implementation. # So there is no reason to create yet another subproject for them HEADERS += iface/IInterface1.h \ iface/IInterface2.h \ # IInterface2 needs QtConcurrent ... IInterface2.h: ...
