Hi Luka,
No, the toolchain is not rebuild. Those options are injected to the
selected cross toolchain. Within a package build (rpm spec file) gcc is
an alias for a toolchain wrapper, the wrapper will pick up and inject
any flags you've set in the config.

Does that mean that gcc is rebulid / setted up so that they are

Hi Luka,
Note that if you run ./ltib -m config you can inject those options by
entering them in the entry:
() Enter any CFLAGS for gcc/g++

I later found what my problem was.
Linking from Ltib libraries in /opt/freescale/... worked but that is
not correct lib folder
I had to linked from<ltib>/ltib-modelo-20100709/rootfs/lib/ and
<ltib>/ltib-modelo-20100709/rootfs/usr/lib/
Trick was that you had to add 3 extra flags (-march=isac -mcpu=54418
-msoft-float) in order to suspensefuly link and now it works like
charm.

Hi Luka,
Which platform is this ? is it from Freescale or from this public
project? If from Freescale you need to ask them.
If this is a Coldfire with MMU (or other MMU), then you should not have
to had anything to your linker path. If it's noMMU then I don't think
pthreads work.
Do not manually add ld xxx commands to your build, just call gcc. So
you just need to add -l pthread to your gcc line.
The problem could be gcc related. I don't think gcc-4.4.45 is used in
the public LTIB.

I have problem using any other than standard libraries.
I am building for MCF54418 and if I add<ltib>/rootfs/usr/lib to
linker path and try to build "pthread.h" application HelloWorld
http://pastebin.com/ugYmSiFU I get error:

How should solve this? I have been trying this for almost 2 days.
