[Qemu-devel] [PATCH 1.0] configure: fix detection for xattr.h on modern distributions |
Date: |
Tue, 8 Nov 2011 16:23:50 +0200 |
Modern distributions place xattr.h in /usr/include/sys, and fold
libattr.so into libc. They also don't have an ENOATTR.
Make configure detect this, and add a qemu-xattr.h file that
directs the #include to the right place.
