编译远程编辑时未定义的参考

Question

我正在尝试在Linux Mint 12上编译Remotepad Server，并且在制作过程中遇到以下错误：

gcc -lXtst -lX11 -lm  -o remotepad remotepad.o ucs2keysym.o

我已经搜索过，它说要确保安装了XSTS软件包。

/home/joe $ ls /usr/lib/libXtst*
/usr/lib/libXtst.a  /usr/lib/libXtst.so  /usr/lib/libXtst.so.6  /usr/lib/libXtst.so.6.1.0

最好使用： gcc remotepad.o ucs2keysym.o -o remotepad -lXtst -lX11 -lm 用于参数排序。未定义的参考肯定在X11库中。也许添加 -L/usr/X11/lib - 或在任何地方找到X库。
