[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

Here are the last words from compilation:
