未定义参考编译RemotePad

Question

我试图编译RemotePad服务器上的Linux Mint的12，并在我收到以下错误时：

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

我GOOGLE和它说以确保Xsts包安装了我所做的。

/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

最好用：gcc remotepad.o ucs2keysym.o -o remotepad -lXtst -lX11 -lm进行参数排序。未定义的引用绝对在X11库中。也许加上-L/usr/X11/lib - 或者找到X库的地方。
