Here we can discuss the common errors or problems someone might have, give advice, post or propose a solution for the problems

Common Errors

If you enable SPE support

It errors out while Installing C library the error code outputs http://pastie.org/1802072 ... hunting the error deeper this is the part that errors out

configure:3294: powerpc64-unknown-linux-gnuspe-gcc    -V >&5
powerpc64-unknown-linux-gnuspe-gcc: '-V' option must have argument
configure:3297: $? = 1
configure:3301: checking for suffix of object files
configure:3327: powerpc64-unknown-linux-gnuspe-gcc    -c -mabi=spe -mspe          -O2  conftest.c >&5
cc1: error: not configured for ABI: 'spe'
configure:3330: $? = 1
configure: failed program was:

At this moment, the toolchain get some errors during the compilation, here the compilation process :

Here is the build.log :

Personnal comment :

I'm gonna retry it, again... apparently, this issue is caused by "no unwind-support". Let's investigate it.

Note : I have not activated SPE support.

Ok guys, everything is finally working on my Ubuntu x86_64 host sytem. All you have to do is to use the latest revision of crosstool-ng and apply the important.patch to the source code, so just follow the steps indicated.

Note : Still not have activated SPE support. I'm going to test the compilation with it, maybe it's my lucky day.

My host has gcc 3.4.6 (couldn't change). So I can't compile PPL (checked.inlines.hh:607: internal compiler error: in invert_truthvalue, at fold-const.c). Are there some workarounds to this problem?

For those of you having the same disability to compile PPL. So far the only solution is to change to GCC 4.8 and use CLOOG-ISL for graphite optimization.
