Subject: Re: Question about missing linux/version.h while statically
 compiling Redis

Thanks to your explainations Nagy, i have understand what was needed.

The compilation goes further but end now here :
debug.c:37:22: error: execinfo.h: No such file or directory

Does execinfo.h is specific to gnu libc ?

Olivier.
