Re: [Ltib] Linking question

[Stuart Hughes]

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.

Regards, Stuart
