ATLAS fails to build on mips

ATLAS fails to build on mipsel64:

http://hydra.gnu.org/build/133025

with

mkdir ARCHS

make -f Make.top startup

make[1]: Entering directory '/tmp/nix-build-atlas-3.10.2.drv-0/build'

Make.top:1: Make.inc: No such file or directory

make[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 on

which it is running.

My first question then is:

If we are cross-compiling, then the only solution that I see it to try

to fix the configuration with parameters passed to configure and give

up on optimization.

I have no practical experience with MIPS, so my next question is: In

the 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 following

relevant 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

P.S.: I'm indeed not subscribed to the bug list. Could you copy me directly?

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, if

I 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 I

pass each parameter as a separate string as in

"-A" "52" "-V" "1"

they are recognized. Do you have a suggestion for how to achieve this

without 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)))

The attempt to get ATLAS on MIPS failed; commit 01480b9e disables it

on MIPS.
