Cross Compiling Axis2 for ARM

[Erik Sallmann - iNTENCE automotive electronics <e....@intence.de>]

Hi,

when I try to cross compile Axis2/c for arm7 (IGEPv2 Plattform) with the angstrom sdk (which seems to be a OE generated toolchain) I get this:

Adding "-rpath /home/jdoe/axis2c-src-1.6.0/axiom/src/parser/libxml2/.libs" to the LDFLAGS into the Makefile in neethi/test resolved the Problem for me.
I've noticed that "--rpath" is used several times. I'm not sure whether that's correct because I didn't find any hints about setting flags with two hyphens and whether it's meant to be "-rpath".

Kind regards

Erik
