I'm working on packaging include-what-you-use (
https://code.google.com/p/include-what-you-use/ ) for Fedora/RHEL (
https://bugzilla.redhat.com/show_bug.cgi?id=1091659 ) and the packaging
guidelines strongly discourage linking against static libraries (
http://fedoraproject.org/wiki/Packaging:Guidelines#Packaging_Static_Libraries
). I'm putting in an exception request for the time being, but are there
any plans in the long term to build the dynamic libraries for clang?
Thanks,
Dave
