Question

我正在尝试构建源代码中包含的libvterm's演示。

我有这个文件夹结构：

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

在我做的演示目录中：

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

即使在definind -I 和 -L 指向正确的目录后，我也会收到很多undefined reference to错误：

我错过了什么？

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链接器更改为首先要求对象，并且库最后/更晚。

gcc链接错误
