Re: error while cross-compiling ORBit2-2.14.1 for "ARM Cortex-A8"

["Amit Pundir" <pundiramit gmail com>]

Thanks for the values.

I cached those values at configuration time and it is configured well
from there but now I got stuck at compilation.
It is trying to execute a cross-compiled binary(meant for arm) and fails.

Here is the appropriate log:

--------------------------------------

--------------------------------------

Any work around for this??

Once in a while when I get situation like this i.e. the compilation
fails during building tests or some checks, I used to skip
building/installing that part of the program.
Should I skip building "orb-core" part or what ? Also, I'm not sure
what purpose "orb-core" source solves in ORBit package.

Thank you very much again for CORBA variables.
