Hi Martin:
I am working on pdb2pqr, an apbs dependency that uses gfortran, gcc,
and g++
It is currently broken on 23-bit 10.6 but works fine on the other
platforms.
If the first three lines are
#!/bin/zsh -f
source %p/bin/init.sh
PATH=%p/bin:%p/sbin:${PATH} ; export PATH
this appears to put everything right, at least in my experiment.
Because of zsh's path anti-metastasis feature, I HAD to do this
explicitly with the path, e.g., this
set +x
print ""
print
"~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"
print ""
print "source %p/bin/init.sh"
source %p/bin/init.sh
print "The path after sourcing the %p/bin/init.sh file"
print "starts with $path[1,6]"
print ""
PATH=%p/bin:%p/sbin:${PATH} ; export PATH
print "now path starts with $path[1,6]"
print "VERSIONER_PERL_PREFER_32_BIT is $VERSIONER_PERL_PREFER_32_BIT"
print ""
print
"~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"
print ""
sleep 10
set -x
gives the following output:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
source /sw/bin/init.sh
The path after sourcing the /sw/bin/init.sh file
starts with /usr/bin /bin /usr/sbin /sbin /usr/local/bin /usr/X11/bin
now path starts with /sw/bin /sw/sbin /usr/bin /bin /usr/sbin /sbin
VERSIONER_PERL_PREFER_32_BIT is yes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This, however, wasn't enough to get gfortran to do the right thing

so I am left having to do a hackish conditional test
[[ "%m" != "x86_64" ]] and manually introducing -m32 where
appropriate.
