Description Peter Robinson 2016-09-05 23:34:39 UTC
recent linbox releases have been failing to build  but actually when investigating the failure looked to be something around fflas-ffpack: from test-rank.h:56, from test-rank-Int.C:33: /usr/include/fflas-ffpack/utils/bit_manipulation.h: In function 'uint64_t divide_128(uint64_t, uint64_t, uint64_t, uint64_t*)': /usr/include/fflas-ffpack/utils/bit_manipulation.h:114:10: error: impossible constraint in 'asm' ); ^ Makefile:2120: recipe for target 'test-rank-Int.o' failed So checking the version that was last successful shows it was fflas-ffpack 2.2.1 that last worked. Doing a scratch build of the latest linbox against fflas-ffpack 2.2.1 shows it builds  against the older version.  http://arm.koji.fedoraproject.org/koji/packageinfo?packageID=4266  http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=3707507
Comment 1 Jerry James 2016-09-06 02:11:30 UTC
Yes, it looks like upstream inserted some x86-specific assembly into one of the header files. I'll scout around and see if they did that anywhere else before reporting this upstream and fixing.
Comment 2 Jerry James 2016-09-06 03:00:43 UTC
Created attachment 1198059 [details] Proposed patch to guard x86-specific asm in fflas-ffpack Is anybody able to build fflas-ffpack with this patch, and then build linbox on top of that? I know how to do an aarch64 scratch build of fflas-ffpack, but don't know how to do 2 dependent builds like this. Thanks.

Thanks. aarch64 builds are now enabled in rawhide/f25 in koji.fedoraproject.org so it's probably easiest to push a build there, newRepo, bump linbox and rebuild.
