Thanks, for my own interest, what was the problem?

>The problem you had was the it was looking in cloog was probably built with the wrong ABI, what happens now is the Cloog uses the same ABI as gmp.

Ah - so the change you made was in "5.10 CLooG-PPL-0.15.3", not in "5.14 Cross GCC-4.4.0 - Final" - that would explain why I didn't spot it...

_______________________________________________
After your modifications, "5.14 Cross GCC-4.4.0 - Final" compiles without error.

However - alone out of the apps in chapter 5, gcc builds 64bit libs (cflags and cxxflags are unset) on my ps3.

Moving to chapter 6, I can see from the ./configure output that gmp is going to build 64bit libs too.

I guess I need to set cflags=cxxflags=-m32 before building "5.14 Cross GCC-4.4.0 - Final" to avoid getting a 64bit system?

-------------
Using Version SVN-20090706-PowerPC64-Multilib, I get the same error as above (exception not handled) in 5.16. Cross GCC-4.4.0 - Final

Does this need a different modification to the one made in powerpc32?
