I don't know how your distribution does these things, but here are some options: * Install the include files into separate directories depending on the arch. * When generating -devel packages, rename /usr/include/event2/event-config.h to /usr/include/event2/event-config-ARCH1.h ... /usr/include/event2/event-config-ARCHn.h, and have a new /usr/include/event2/event-config.h that conditionally includes the right one. This is nice and easy if you can get away with it on your platform (as you probably can for word size), but not if you have to support multiple architectures that you can't distinguish at compile time. * Install event-config.h to /usr/lib/libevent/include/event2 and/or /usr/lib64/libevent/include/event2 as appropriate; adjust the .pc files as needed. This will break the build process of anything that doesn't use pkgconfig, so other packages might need patching too. There are probably other options as well, but these are the ones I've seen distributions do in the wild. If your doesn't handle the case correctly, you should probably file a bug with whoever maintains its Libevent package. hth, -- Nick Mathewson *********************************************************************** To unsubscribe, send an e-mail to majord...@freehaven.net with unsubscribe libevent-users in the body.
