How can i do the same ??

I understand that i have to use :--with-idl-compiler option while
configuring ORBit2.
One catch here is if i will give--with-idl-compiler=/usr/bin/orbit-idl-2
then it will build for me.
But i think in this case it uses orbit-idl-2 binary built for host & it
will not run on target.

configure happen successfully for me & i can see that while compiling it
is using header from path used for cross compilation.

If someone has cross compiled ORBit then please do share their result or
idea to solve the problem.
