致命错误：找不到'X11/Xlib.h'文件

Question

我已经安装了XQuartz。我使用 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)

如果我像这样编译：

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

法典：

#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。如果有人感兴趣：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
