Re: [Gems-users] Error compiling Ruby

[Dan Gibson <degibson@xxxxxxxx>]

Does the problem arise when linking the simics module or when linking 
the Ruby tester? Does your ld.so.conf include the appropriate 
directories for libz? What happens when you add -lz to LDFLAGS and 
MODULE_LDFLAGS (it should already be there, if I remember correctly)?
Regards,
Dan
