Comment(by drkirkby):
I'm confused, this appears to have been incorporated in atlas-3.8.3.p5, so
I think this can be classed as fixed.
Here's the relavent bits of SPKG.txt
== ChangeLog ==
=== atlas-3.8.3.p5 (David Kirkby, June 24th 2009) ===
* Made a backup of ATLAS-build/lib/Makefile to ATLAS-
build/lib/Makefile.orig
* Alter the flags in ATLAS-build/lib/Makefile with those that will work
if the linker
used is the Sun linker. The default Makefile makes use of the GNU
linker's
flags, such as "-shared" which is not acceptable to the Sun linker.
The patch is only applied if the operating system is Solaris, and the
linker is not the GNU linker. The flags charged are:
-shared ==> -G
-soname ==> -h
--whole-archive ==> -z allextract
--no-whole-archive ==> -z defaultextract
NOTES:
1) Sun have a tool which accepts gcc flags, but calls the Sun
compiler.
This patch might mess things up if that is used. Having never used the
tool
it's impossible to be 100% sure of this. Anyway, that will be some
time in
the future, so this patch can be removed.
2) The fact the linker flags are GNU specific has been reported to the
ATLAS
maintainer, so they may fix this problem. In which case the patch
could be
removed at a later date.
* Fixed a minor spelling mistake in this file
=== atlas-3.8.3.p4 (David Kirkby, June 16th 2009) ===
* Change GuessSmallNB() in src/tune/blas/gemm/mmsearch.c
as suggested by Clint Whaley to return 28
on Solaris. This is ONLY A TEMPORARY FIX and once the real problem
in the function is sorted out, this fix will need to be removed. But
for now it permits ATLAS to build on a Sun T5240 with gcc-4.4.0.
