Question

我已经安装了XQuartz。我用g ++编译：

g++ -o -lX11 -I/opt/X11/include window2.cc

错误

Undefined symbols for architecture x86_64:

"_XCreateWindow", referenced from:
  _main in window2-dXb9bZ.o
 "_XFlush", referenced from:
  _main in window2-dXb9bZ.o
"_XMapWindow", referenced from:
  _main in window2-dXb9bZ.o
"_XOpenDisplay", referenced from:
  _main in window2-dXb9bZ.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

如果我这样编译：

g++ window2.cc -o window -lX11 -I/opt/X11/include

错误

ld: library not found for -lX11
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我确定Xlib.h在/ opt / X11 / include

中

代码：

#include <X11/Xlib.h>
#include <unistd.h>

int main()
  {
  // Open a display.
  Display *d = XOpenDisplay(0);

 if ( d )
{
  // Create the window
  Window w = XCreateWindow(d, DefaultRootWindow(d), 0, 0, 200,
                           100, 0, CopyFromParent, CopyFromParent,
                           CopyFromParent, 0, 0);

  // Show the window
  XMapWindow(d, w);
  XFlush(d);

  // Sleep long enough to see the window.
  sleep(10);
}
 return 0;
 }

我该如何解决这个问题？提前致谢

Answer 1

问题已解决。万一有兴趣的人：你必须像这样编译：

g++ -o window window.cc -I/usr/X11R6/include -L/usr/X11R6/lib -lX11

Answer 2

尝试

cc -I /opt/X11/include/ test.c -L /opt/X11/lib -lX11

致命错误：＆＃39; X11 / Xlib.h＆＃39;文件未找到
