There is a libmesh.pc per method, and they get installed inside the lib directory for that method. I could refactor it to use e.g. $ pkg-config libmesh --define-variable=METHOD=dbg and default to opt - would that be preferable? -Ben ------------------------------------------------------------------------------ Monitor your physical, virtual and cloud infrastructure from a single web console.
