[microblaze-uclinux] Problem with mb-gcc and include paths

Board: Memec spartan 3 dev board.

Microblaze cross tools : available from John's site (http://www.itee.uq.edu.au/~jwilliams/mblaze-uclinux/Toolchain/toolchain_sources.html)

I have succesfully tested a hello world on the board, so the elf tools are ok.

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

However, when I try to compile a udpserver, I get the following error.

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

[user@rndLinux udpHeartBeat]$ make
mb-gcc -o talker.mb talker.c
talker.c:6:29: netinet/in.h: No such file or directory
talker.c:7:23: netdb.h: No such file or directory
talker.c:8:28: sys/socket.h: No such file or directory
--------------------

I cannot find socket.h under the microblaze tools directory, but it is available under my linux source directories. I am guessing I need to point mb-gcc to that tree as well, but using -I is not helping the situation. Any help anyone can provide me will be much appreciated.

Thanks

Manu Rao

PS: source code I was trying to compile is attached.
