Hi all,

I think I changed config.arch according to Yasushi' patch (and attached is
the config.arch file I modified) and put libxil.a in /uClinux-dist/lib.

I selected Insignt/mbvanilla_net just to see if this compiles fine.
Then, I encounted other errors like below.

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

I tried several times to get it compiled, but couldn't.

Could anyone please help me why this gives me errors after fixing
crypt_old and xil problems?

Thanks,

Taeweon
