Hi,

Geany doesn't have a debugger or Valgrind support, so I guess you are 
using one of the debugging plugins? I would try to clean build and get 
it running outside of Geany from the command line, after your build 
issues are sorted out (ex. it looks like you're linking "eglibc" in your 
home directory rather than some system-wide C stdlib, maybe on 
purpose?), I bet it will work with any of the debugging plugins. 
Valgrind should be totally unrelated to any of this.

Cheers,
