Actually, some of them don't ship .a libs in -devel packages anymore so you can have all the right paths and it'll still fail. See if you have "-static" in your build options. Longer explanation: you can link your code to dynamic libraries (.so) or create a self-contained "static" executable. The latter requires a "static" library that some linux distribution vendors and/or package maintainers no longer provide. -- Dimitri Maziuk Programmer/sysadmin BioMagResBank, UW-Madison -- http://www.bmrb.wisc.edu
