Hello

Thanks for the link to nslu2 and the information that I basically just need to set these bunch of variables correct for cross compiling. I was now able to create a mostly working package for Buildroot. The .mk file is attached for others which may run into the same situation.

Thanks

Benjamin

I haven't cross compiled in a long time ...
For proper cross-compilation, the CROSS_COMPILE flag must be set to
something, then the LOCALBASE and SYSBASE should point to the staging
directory where the toolchain and all the libraries and include files
for the target platform are present.
Extra compile and link options can be passed via CC_EXTRA_OPTS and
LD_EXTRA_OPTS.

An old example for optware can be found here:
https://raw.githubusercontent.com/nslu2-linux/Optware/master/make/kamailio.mk

Some modules have a proper Makefile that will use the pkg-config from
staging directory and detect proper compile and link flags while other
modules require manual tinkering with the Makefile.
It's good to enable the noisy build (Q=0) and check that proper
include files and libs are used (from the staging directory and not
from the build machine).

Regards,
Ovidiu Sas
