Re: Problem building cross-compiler for AIX 6.1

[David Summers <gmane at summers5913 dot freeserve dot co dot uk>]

With my experience, a few posts down.

First pass of gcc in a cross compiler, you have to disable both threads 
and shared. Problem is that both depend on files that you only create 
when you compile your target C library, and you can only compile that 
when you've a basic compiler working.

So first compile with --disable-shared --disable-threads

Then do your C lib

Then recompile with shared and threads enabled, and making sure you are 
pointing things to the new files created by the C lib ....

Hope this helps,

David.
