atlas +gcc48 does not build

Reported by: eschnett (Erik Schnetter) Owned by: Veence (Vincent)
Priority: Normal Milestone:
Component: ports Version: 2.3.1
Keywords: Cc:
Port: atlas

Description

The command

sudo port install atlas +gcc48

aborts with the error message

:info:build make[2]: *** No rule to make target `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_math_atlas/atlas/work/ATLAS/build/..//CONFIG/ARCHS/Core264AVX.tar.bz2', needed by `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_math_atlas/atlas/work/ATLAS/build/ARCHS/Core264AVX'.  Stop.

Ooops. AVX instructions are enabled, and they should not. Can you give me the output of

sysctl -a hw

Thanks!

Note: My CPU supports AVX instructions. The default assembler does not, and Atlas's build process outputs a note to that respect in the beginning of the log file ("disabling AVX" or similar). However, I replaced /opt/local/bin/as with a script that calls a different assembler, so that AVX instructions work fine on my system. Maybe there is a configure check for AVX that unexpectedly succeeds?

comment:4 Changed 6 years ago by Veence (Vincent)

Uh. It's a rather good idea, but I think gcc calls /usr/bin/as and not /opt/local/bin/as (despite what the configuration process says). If you want to persevere in that course ;), rename /usr/bin/as to, e.g. /usr/bin/AS and make /usr/bin/as a link to /opt/local/bin/as then retry.

As a test, if you have not cleaned your build, you can cd into /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_math_atlas/atlas/work/ATLAS/build/src/blas/level3/kernel and try:

If it compiles correctly, then you've the green light.

comment:5 Changed 6 years ago by eschnett (Erik Schnetter)

I find that gcc is calling /opt/local/bin/as; I can use AVX instructions with gcc fine.

I was able to build Atlas with gcc48 by temporarily removing my AVX-enabling assembler.

How do you want to proceed? Do you want to keep Atlas as-is (and I'll have to work around this problem), or do you want to update its AVX detection so that it would use AVX instructions in my case?

comment:6 Changed 6 years ago by Veence (Vincent)

Ok. Great. I think there is a conflict between the options -DATL_AVX and -msse4.2.

-DATL_AVX is probably automatically added by Atlas as it detects that AVX instructions are successfully compiled, whereas -msse4.2 is the standard way to disable to use of AVX instructions with gcc4.8 and is part of the Portfile standard behavior.

Since your installation is non-standard, I'd prefer to keep the Portfile the way it is. Is there a reason why you don't use 'clang' and the 'perf' option, which handles AVX cleanly by using the dragonegg front-end?
