ATLAS fails to build on mipsel64: http://hydra.gnu.org/build/133025withmkdir ARCHSmake -f Make.top startupmake[1]: Entering directory '/tmp/nix-build-atlas-3.10.2.drv-0/build'Make.top:1: Make.inc: No such file or directorymake[1]: *** No rule to make target 'Make.inc'. Stop.make[1]: Leaving directory '/tmp/nix-build-atlas-3.10.2.drv-0/build'
Can this be repaired, or is the package not supposed to work on mipsel64?In the latter case, we would need to disable it for this architecture.

What I see is that ATLAS is not able to detect the type of system onwhich it is running.
My first question then is:
* Are we corss-compiling, or are we on proper hardware?
If we are cross-compiling, then the only solution that I see it to tryto fix the configuration with parameters passed to configure and giveup on optimization.
I have no practical experience with MIPS, so my next question is: Inthe list of architectures supported by ATLAS I see:
49 = 'MIPSR1xK'50 = 'MIPSICE9'
Is one of the two appropriate?
Also ATLAS wants to know about ISA extensions. Is any of the followingrelevant or should I pick 'none'?
none: 1 VSX: 2 AltiVec: 4 AVXMAC: 8 AVXFMA4: 16 AVX: 32 SSE3: 64 SSE2: 128 SSE1: 256 3DNow: 512 NEON: 1024

No, it is native on a mips machine.

No idea. But there is a debian package for mipsel, described as"The libraries in this package are built without any processor extension instructions, and should run on all processors of this general architecture, albeit less than optimally."

2 and 4 are for powerpc, 8 to 512 for x86 and 1024 for arm. So "none"should be best.

I'm trying to pass an architecture parameter to configure. However, ifI do something like
... #:configure-flags `(... ;; On non "x86_64" / "i686" platforms, do not guess processor ;; architecture (because it fails) and do not use ISA extensions. ;; We set MACHINETYPE = 52 'generic' and ISA = 1 'none'. ,,(if (not (and (string-prefix? "x86_64" (%current-system)) (string-prefix? "i686" (%current-system)))) "-A 52 -V 1")...
the configure flags are not recognized. Differently from this, if Ipass each parameter as a separate string as in
"-A" "52" "-V" "1"
they are recognized. Do you have a suggestion for how to achieve thiswithout 4 equal 'if'?

You should put the different configure flags as elements of a list.To concatenate with an existing list, you can do something like this(taken from xkbcomp): (inputs `(,@(package-inputs xkbcomp-intermediate) ("xkeyboard-config" ,xkeyboard-config)))

tag 18933 wontfixclose 18933thanks
The attempt to get ATLAS on MIPS failed; commit 01480b9e disables iton MIPS.
Seehttps://lists.gnu.org/archive/html/guix-devel/2014-11/msg00516.htmlfor the discussion.
