我可以在没有 qmake 或 Qt Creator 的情况下使用 Qt 吗?
我想使用 Qt 编程,但我不想使用特殊的编译器或 IDE,例如 Qt Creator 和 qmake.我想和 Kate 一起写,用 g++ 编译.
I want to program using Qt, but I don't want to use special compilers or IDE such as Qt Creator and qmake. I want to write with Kate and compile with g++.
我可以用g++编译一个使用Qt的程序吗?我如何用 g++ 编译它?
Can I compile a program that uses Qt with g++? How do I compile it with g++?
推荐答案
当然可以.虽然用 qmake 或 CMake 更方便,但你可以这样做:
Sure you can. Although it is more convenient with qmake or CMake, you can do:
CXXFLAGS += -Ipath_to_your_qt_includes
LDFLAGS += -Lpath_to_your_qt_libs
LDLIBS += -lqt-mt (for Qt3)
或
LDLIBS += -lQtCore -lQtGui (for Qt4, add what you need)
my_prog: my_prog.cpp
(在生成文件中)
更新 - 调用 moc
:
引用自 moc 手册页:
这是一个有用的 makefile 规则,如果您只使用 GNU make:
Here is a useful makefile rule if you only use GNU make:
m%.cpp: %.h
moc $< -o $@
我个人将输出命名为 %.moc.cpp
(而不是 m%.cpp
).然后将 my_prog
的依赖添加到 my_prog.moc.cpp
I'd personally name the output rather %.moc.cpp
(than m%.cpp
). You then add the dependency of my_prog
on my_prog.moc.cpp
my_prog: my_prog.cpp my_prog.moc.cpp
同样适用于 uic.这里的情况更复杂,因为你必须为头文件和生成规则,并且你必须添加对头文件的依赖以确保它在源代码编译之前生成.像这样的事情可能会奏效:
Similarly for uic. The situation here is more complicated, since you have to generate rules for headers and source files, and you have to add a dependency on a header file to ensure it gets generated before the sources are compiled. Something like this might work:
my_prog: my_prog.o my_prog.moc.o my_prog.ui.o
$(CXX) $(LDFLAGS) -o my_prog $^ $(LDLIBS)
my_prog.o: my_prog.cpp my_prog.ui.h
