问题描述

我想使用Qt编程,但我不想使用特殊的编译器或IDE,如Qt Creator和qmake。我想用Kate编写并用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++.

我可以编译一个使用Qt和g ++的程序吗?如何用g ++编译?

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。虽然使用qmake或CMake更方便,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)

LDLIBS += -lQtCore -lQtGui (for Qt4, add what you need)

my_prog: my_prog.cpp

(在makefile中)

(in a makefile)

更新 - 调用 moc

规则如果你
只使用GNU make:

Here is a useful makefile rule if you only use GNU make:

m%.cpp: %.h
        moc $< -o $@


code>%。moc.cpp ( m%.cpp )。然后,在 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

类似地,对于 uic 。这里的情况更复杂,因为您必须为标头源文件生成规则,并且必须在头文件上添加依赖关系,以确保它在源编译之前生成。这样的东西可能工作:

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
