• include/c++/4.6.3/bits/stl_algobase.h:329 : undefined reference to

  27 novembre 2013, par user3041105

  My program is fails to compile with this error when I use my own account but when use the root account it compiles successfully. I have installed boost, ffmpeg and opencv.

  The errors are as follows :

• ffmpeg link error : undefined reference in library sources

  31 janvier 2016, par Arton

  I downloaded the ffmpeg from git, and make the libs by sources. Created main.c as below and put the ffmpeg libs in the same folder as main.c, (my system is ubuntu 15.10, gcc version 5.2.1)

  #include 
  
  void av_register_all(void);
  
  int main() {
  
      printf("abc\n");
  
      av_register_all();
  
      return 0;
  
  }

  After I issued gcc main.c -L. -lavformat -lswscale  -lavcodec -lswscale -lavutil -lavdevice -lavfilter, I got a lot of (nearly 1000) undefined reference errors :

  ...
  
  /home/arton/sources/ffmpeg/libavcodec/vorbisdec.c:868: undefined reference to `atan'
  
  /home/arton/sources/ffmpeg/libavcodec/vorbisdec.c:868: undefined reference to `atan'
  
  /home/arton/sources/ffmpeg/libavcodec/vorbisdec.c:869: undefined reference to `atan'
  
  /home/arton/sources/ffmpeg/libavcodec/vorbisdec.c:869: undefined reference to `atan'
  
  /home/arton/sources/ffmpeg/libavcodec/vorbisdec.c:869: undefined reference to `floor'
  
  ...

  /home/arton/sources is where the ffmpeg sources at, I have no idea why it report the sources path of ffmpeg and why the link fails. Any hint is appreciated. Thanks !
