I got a BZ for a package I maintain from someone who needs multilib support without using Mock: https://bugzilla.redhat.com/show_bug.cgi?id=595923 I found myself asking what the requirements are for a -devel package. In general, do we support this in -devel libs or not? On IRC, I think I've learned that the answer is "yes", but .... .... this also made me realize that I really don't know what other requirements we may have for -devel packages, I wondered if everyone building -devel packages is providing multilib support, and I wondered if we need some way to detect conflicts among headers for multiple architectures. In this case, the problem was a conflict in the size of a long: #define XERCES_SIZEOF_LONG 4 vs. #define XERCES_SIZEOF_LONG 8 Are there other requirements for -devel packages that I should be aware of? Is there something I should read? Jonathan -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
