我使用Eclipse,我想在其中使用gtkmm。我有以下代码:
#include <gtkmm.h>
#include <iostream>
int main(int argc, char *argv[]) {
Gtk::Main kit(argc, argv);
Gtk::Window mainWindow;
Gtk::Button button("Click here");
mainWindow.set_title("Eclipse/GTKmm Demo");
mainWindow.set_border_width(4);
mainWindow.set_default_size(200, 50);
mainWindow.add(button);
button.show();
Gtk::Main::run(mainWindow);
return 0;
}
我添加了pkg-config --cflags --libs gtkmm-3.0
(当然有严重的口音)将Cross G ++ Compiler Miscellanous选项添加到Other标记中,并将Cross G ++ Compiler Miscellanous选项添加到Linker标记中。它不起作用!
这是编译日志:

我不知道为什么......当我在终端编译它时:g++ -O0 -g3 -Wall -c -fmessage-length=0 'pkg-config --cflags --libs gtkmm-3.0' -o ./test ./main.cpp
它可以工作......

我找到了一个解决方案:
在链接器选项中,在命令行模式中,我将${FLAGS}
移到了末尾,例如:
之前:${COMMAND} ${FLAGS} ${OUTPUT_FLAG} ${OUTPUT_PREFIX}${OUTPUT} ${INPUTS}
之后:${COMMAND} ${OUTPUT_FLAG} ${OUTPUT_PREFIX}${OUTPUT} ${INPUTS} ${FLAGS}
现在它有效。

您必须将pkg-config --cflags <etc>
添加到现在的位置(编译器选项),然后将pkg-config --libs <etc>
添加到链接器选项
