cross compiling a library with ELDK

[Murat Artun]

Wolfgang,

Thanks for your response...

I confess I did not read the whole documentation from scratch, but I
have browsed many sections especially related with my issue. I should
say it is always said in documentation that setting $CROSS_COMPILE
environment variable is necessary, but that did not work for me.

Specifically, I am trying to cross compile osip library with EDLK (not
an ELDK component). When I execute the configure script I want the
config.h to be generated to reflect the target system. As from your
last response I understand that I always need to make sure by checking
config.h file myself.

After I have posted this problem I found the below thread:

http://ozlabs.org/pipermail/linuxppc-embedded/2003-July/011785.html

Following the same, I have achieved generation of config.h by checking
ELDK components and GNU cross tools to be prefixed with ppc_8xx.

Although I was not able to build shared libraries with the generated
makefile, building static libraries was OK. But it seems as if it is
somehow difficult to cross build a SW component that is not a part of
ELDK, and this is harder than "Rebuilding ELDK Components" which is
specified to be so straightforward in the documentation.

Thanks and regards...
