GCC链接错误

Question

我试图建立包含在源libvterm's演示。

我有这样的文件夹结构：

- libvterm/ 
    ... // all sources are here 
    - libvterm.so 
    - vterm.h 
    - demo/ 
    - vshell.c 

在演示目录我所做的：

$ gcc -o vshell `pkg-config --cflags --libs glib-2.0 ncurses` vshell.c -L.. -I.. -lvterm 

我得到很多undefined reference to错误的，即使经过definind -I和-L指向正确的目录：

尝试重新安排你的链接命令

gcc -o vshell vshell.c -L.. -I.. -lvterm `pkg-config --cflags --libs glib-2.0 ncurses` 

在某些时候，GNU链接改为首先要求对象和库最后/晚。
