Re: [Help-glpk] Linker error while compiling with glpk.h

[glpk xypron]

Hello Psalm,

after installing a new library like libglpk.so in /usr/lib or
/usr/local/lib you may have to call

sudo ldconfig

to ensure that the library will be found.

Cf.
http://en.wikibooks.org/wiki/GLPK/Linux_OS

Best regards
