[Samba] Cross Compile Samba4

[Sebastian Ulmer]

Hi,

I try to port samba4beta8 to Optware which includes cross compiling it
for various platforms. I already created makefiles for optware for samba
versions 3.4 and 3.6. Creating a working makefile for samba4 I try to
use the new build environment but it puzzles me. I don't get over part
where the python version is being checked. From my findings it looks
like the linker dislikes the argument "-Bsymbolic-functions". I tried to
find the part of the buildscript where this option is set, but didn't
find it. Unfortunately I cannot switch to a newer compiler, which
supports this argument. I tried to use option --nopyc, but that did not
help. Further I did notice that the scripts does not find the correct
python version of the target platform and uses host python and I don't
how to change that. I would appreciate any help. A example makefile on
how to cross compile samba36 can be found here:
http://trac.nslu2-linux.org/optware/browser/trunk/make/samba36.mk

Sorry for not getting back to you sooner.

The cross-compile support isn't tested very often, and it may need some
work in various areas to improve it. It certainly seems likely that we
assume the python version is the same (as of course the build system is
built with python).

Sadly I can't really help much right now, you may find it less
frustrating to switch to newer tools than to try and figure this out.
