Comment(by drkirkby):
What version of gcc is this failing with? I assume it is not 4.6.0, but
can you confirm that?
This error message reminds me of ones that existed with R and ECL on
Solaris. The ECL bug has been fixed, but not the R bug (#9040), so R will
not build 64-bit on Solaris x86 with gcc. The R bug is caused by a shared
library being built with position dependent code. There are some
conditions that can cause non-PIC code to be generated even when the flag
-fPIC is given.
I would check if -fPIC is being passed first. I had a long battle with the
Singular developers to get them to accept that -fPIC should be used on
Solaris. I think I'd convinced them on Linux too, but never tried on OS X.
It could be that there's no -fPIC flag and it just happens this is ok with
-O3 but not with -O2.
Take a look at
http://blogs.sun.com/rie/entry/my_relocations_don_t_fit
which discusses this issue. It is a Sun blog aimed at Solaris, but the
error message seems remarkably similar. Which makes me think this might be
a PIC/non-PIC issue.
Time for bed here - it is 0300 local time!!
