Created attachment 213687 [details] build.log
Reference to upstream bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=25534 It's a bug in binutils, so a solution is to upgrade binutils to version 2.19 or higher. ARM NEON support is relatively new, so it needs time for all the bugs in gcc / binutils to be ironed out.
Is this confirmed, then?
Happens to me on armv5te as well, without neon...
Well...this uses neon even if the cpu doesn't support it... @x11: please add --disable-arm-neon meanwhile, so it can go stable. Thanks
(In reply to comment #4) > Happens to me on armv5te as well, without neon... Have you tried upgrading binutils? IMHO it is the best way to solve this problem. > Well...this uses neon even if the cpu doesn't support it... Support for NEON optimizations is compiled in automatically if the toolchain supports it, but still the decision whether to use NEON optimized functions is made at runtime. So armv5te should be perfectly fine even with neon-enabled pixman. This behaviour is exactly the same on x86 and ppc. Adding 'neon' use flag would make sense in order to reduce library size for systems which do not need neon. > @x11: please add --disable-arm-neon meanwhile, so it can go stable. Do you think it is the best option?
By the way, there is also a possibility that you additionally need this patch for pixman: http://cgit.freedesktop.org/pixman/commit/?id=a47b5167c4c1b55b2f51e29ab0782c2659bec312 Please also always provide some error logs if/when having any kind of build failures different from what has been already reported. They make it much easier to identify what could be wrong. Thanks.
Applying the above patch succeeds but does not resolve this bug.
Since we now have binutils-2.19.1 stable on arm this can be closed.
