使用 vorbis 库时如何编译 .c 文件。 对 vorbis_info_init 的未定义引用

Question

I installed libvorbis-div with sudo apt install libvorbis-dev . But when i tried to compile my simple code with gcc ac command, i get "undefined reference to `vorbis_info_init'" error.

ac

#include "vorbis/codec.h"
int main(int argc, char **argv){
   vorbis_info vi;
   vorbis_info_init(&vi);
   return(0);
}

Answer 1

If you are only running gcc ac, then you are missing the linker arguments. You should introduce the library you are using to the compiler/linker, which in this case is gcc.

PS Probably just add -lvorbis, but don't just copy-paste, parse these flags in your brain!
