Don't have a Fedora box in front of me to test on, but it might not be available if you don't supply "-lm" (in theory only applies to linking the libraries, but I think it can have other effects), and may need to specify a standard that includes it, possibly --std=c99 or --std=gnu99 to get the right definitions available. Defining _DEFAULT_SOURCE suggested by Kevin Kofler may have a similar effect if your build system is forcing c89 or something. -- imalone http://ibmalone.blogspot.co.uk -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
