Re: [Valgrind-users] Montavista cross compilation

Ahh, makes sense.

I added a random abort() function to one of the files, everything compiles successfully now.

Thank you. :-)

It looks like your libgcc has references to the abort() function in the
C library but we (deliberately) don't link the with the C library.

libgcc is supposed to be low level support routines for gcc generated
code to call and shouldn't really be calling C library routines like
that as it stops you being able to compile code that doesn't link with
the C library.
