atlas-3.8.3 doesn't build on darwin-ppc

[carsten@…]

When trying to install gimp-2 with quartz enabledment I stumbled over the problem that the atlas-package doesn't build. Due to some preprocessor definitions the build process activates x86 inline assemblies:

/opt/local/bin/gcc-mp-4.3 -c -DL2SIZE=4194304 -I/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_math_atlas/work/atlas-3.8.3/build/include -I/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_math_atlas/work/atlas-3.8.3/build/..//include -I/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_math_atlas/work/atlas-3.8.3/build/..//include/contrib -DAdd_ -DF77_INTEGER=int -DStringSunStyle -DATL_OS_OSX -DATL_ARCH_PPCG5 -DATL_CPUMHZ=2000 -DATL_AltiVec -DATL_GAS_PPC -DPentiumCPS=2000 -DATL_NCPU=2 -mpowerpc64 -maltivec -mabi=altivec -mcpu=970 -mtune=970 -faltivec -force_cpusubtype_ALL -O3 -fno-schedule-insns -fno-rerun-loop-opt -fPIC -m32 ATL_walltime.c

My first assumption is that defining the variable PentiumCPS is causing this hassle. I'll try this patch first:

Will make updates as soon as I know more.

brief patch proposal

This patch to the package portfile makes atlas build on darwin-ppc

[carsten@…]

Ok, atlas now builds on my darwin-ppc system. I didn't use the patch to Make.inc as proposed but patched the atlas package Portfile instead (the patch is attached). The patch actually takes care that the preprocessor variable PentiumCPS is only set for x86-architectures. I still don't know whether the built atlas package actually works .... I'll see.

Looked over the patch, thank you for catching this.

I removed the -D c -DPentium declaration from the pre-configure and added two additional targets. One to set Pentium cpufreq and another to set the clock to WALL time as suggested in the ATLAS installation guide section 3.4 for all non-intel cpu's.
