Re: Problem compiling gcc 4.2.1 on AIX 5.3
Anant,
We also use gcc and the aix system linker and we don't use the
-Wl,-bbigtoc linker option, but
compile files with -mminimal-toc.
Have you tried to configure & build with the setup I emailed yesterday?

I have resolved the problem of sed, now compilation fails at this stage:

make[3]: *** [cc1-dummy] Error 1
So my advices are to check what this exit code 12 means and what
that '-bbigtoc' means and whether it could clash with the GCC defaults
for code production, the linker not
really understanding it, or something...
I browsed the documentation :
http://gcc.gnu.org/install/specific.html#x-ibm-aix
once again and saw there really being this note :
"Some versions of the AIX binder (linker) can fail with a relocation
overflow severe error when the -bbigtoc option is used to link
GCC-produced object files into an executable that overflows the TOC. A
fix for APAR IX75823 (OVERFLOW DURING LINK WHEN USING GCC AND -BBIGTOC)
is available from IBM Customer Support and from its
techsupport.services.ibm.com <http://techsupport.services.ibm.com/>
website as PTF U455193."
You should check if this is the case...
