我正在尝试构建包含在源代码中的libvterm 的演示。

我有这个文件夹结构：

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

在演示目录中我做了：

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

undefined reference to即使在定义-I和-L指向正确的目录之后，我也会遇到很多错误：

尝试重新排序您的链接命令...

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

在某些时候，gnu 链接器更改为首先需要对象，最后/稍后需要库。
