Do you have the contrib-plugins package installed ?
No... I've just seen the point, but I have compiled CodeBlocks. And when I try to compile help_plugin alone, I get the error:
/usr/bin/ld: cannot find -lsqplus
/usr/bin/ld: cannot find -lsqstdlib
/usr/bin/ld: cannot find -lsquirrel
I've googled for it, but nothing useful found. Any help will be appreciated. Thanks!
