Apparently the patch didn’t really help: http://hydra.gnu.org/build/167383
Seems like it insists on compiling x86 assembly, which fails: --8<---------------cut here---------------start------------->8--- probe_arch.o: In function `ATL_tmpnam': /tmp/nix-build-atlas-3.10.2.drv-0/build/../ATLAS//CONFIG/include/atlas_sys.h:224: warning: the use of `tmpnam' is dangerous, better use `mkstemp' /tmp/nix-build-atlas-3.10.2.drv-0/build/../ATLAS//CONFIG/src/backend/cpuid.S: Assembler messages: /tmp/nix-build-atlas-3.10.2.drv-0/build/../ATLAS//CONFIG/src/backend/cpuid.S:32: Error: unrecognized opcode `subl $8,%esp' /tmp/nix-build-atlas-3.10.2.drv-0/build/../ATLAS//CONFIG/src/backend/cpuid.S:33: Error: unrecognized opcode `movl %ebx,(%esp)' [...] make[2]: *** [xarchinfo_x86] Error 1 --8<---------------cut here---------------end--------------->8--- At this point I think it’s OK to remove MIPS from ‘supported-systems’ for this package, with a comment pointing to these discussions in case someone wants to investigate. WDYT? Thanks, Ludo’.
