Re: [microblaze-uclinux] Fwd: Problems cross-compiling oRTP

Thank you very much David and John for your answers.

I have clarified very much the idea of how to build a GNU ./configure style apps with a cross compiler.
As you said me David, I have copied makefile1 to user/ortp (cp makefile.1 user/ortp/makefile
). I am sure that my dist uses ucfront because I have built httptunnel (the makefile is of the same type) successfully.

When I try to compile uClinux I get an error. I don't think that it is a thing of oRTP because with quagga I get the same error:

If you meant to cross compile, use `--host'.
See `config.log' for more details.

I don't know if it is a chance but I think that among all the GNU ./configure apps under user I only get to build those apps whose .c files are in the same directory that the makefile. In the case of quagga or ortp, the makefile is not in the same directory of .c files.


Is this ok?


Any advice?

Pello

Take a look at, e.g. user/eth-tools for an example of how to bulid GNU
./configure style apps within the petalinux build environment.
