让gtkmm-4.0在Mac OS Monterey上运行时遇到问题。
下面是一个使用gtkmm4的简单C++应用程序。
// helloworld.cpp
#include <gtkmm.h>
class MyWindow : public Gtk::Window
{
public:
MyWindow();
};
MyWindow::MyWindow()
{
set_title("Basic application");
set_default_size(200, 200);
}
int main(int argc, char* argv[])
{
auto app = Gtk::Application::create("org.gtkmm.examples.base");
return app->make_window_and_run<MyWindow>(argc, argv);
}
然后，我用g++编译了这个应用程序，然后通过llvm-cxxfilt去映射错误消息。
g++-11 helloworld.cpp -o helloworld `pkg-config --cflags --libs gtkmm-4.0`
Undefined symbols for architecture arm64:

问题：有人知道我为什么会出现上述错误，以及我如何编译C++应用程序吗？
这是pkg-config --cflags --libs gtkmm-4.0的输出

我使用的是带有arm64架构的macOS Monterey。
% arch
arm64
在MacOS Monterey、Mac M1和g++(Homebrew GCC 11.3.0(11.2.0上使用llvm cxxfilt对此行编译的输出
g++helloworld.cpp-o helloworldpkg-config --cflags --libs gtkmm-4.0我得到：

缺少链接库吗？如何在MacOs上编译gtkmm4简单文件？提前谢谢。
