patch to fix userspace
This patch fixes the issue of not being able to build the dhcpv6 package. Can
we see about getting this into fedora? When dhcpv6 fails to build that can
also cause anaconda to fail (and anaconda is important!).
I will also see about getting this committed upstream but not sure if there was
a reason for not taking it a while back as I did find it is in -mm but not in
linus's tree.
thanks,
- Doug
This has been fixed upstream and that fix was pulled into fedora in a recent kernel pull. Closing this BZ. |
Description of problem: Some packages include <linux/ipv6.h> which eventually includes <asm/gcc_intrin.h> which fails to build on ia64 outside of the kernel. There are likely other paths where gcc_intrin.h is included as well but this is the one I am running into (when building the dhcpv6 package on ia64). The failure can most easily be reporoduced with a 1 liner c program that does nothing but: #include <linux/ipv6.h> when compiling this it fails with: # cc foo.c In file included from /usr/include/asm/intrinsics.h:18, from /usr/include/asm/byteorder.h:10, from /usr/include/linux/ipv6.h:5, from foo.c:3: /usr/include/asm/gcc_intrin.h:26: error: expected ‘,’ or ‘;’ before ‘__attribute_used__’ The problem is __attribute_used__ is defined in linux/compiler-gcc3.h and compiler-gcc4.h neither of which are packaged with the userspace kernel-headers package. I did some digging and it appears this patch was included in -mm: http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.18-rc1/2.6.18-rc1-mm2/broken-out/git-hdrcleanup-vs-git-klibc-on-ia64.patch I am guessing this was never pulled into the upstream kernel because technically the kernel is not broken since it has all the needed .h files and __attribute_used__ is defined. It is just when we pull those out of the usperspace that the problem is introduced. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3.
