[vlc] Re: Porting VLC on MIPS

[kartikay malhotra]

I tried contrib. I modified contrib/config.mak:
HOST = mipsel-linux
CC = mipsel-linux-gcc

Everything was working fine until it reached ffmpeg, where the compilation
halted due to connection refused by
pserver:anonymous at mplayerhq.hu (213.144.138.186).

I tried to use source forge CVS, but although the checkout succeeds, it is
unable to comply with install-libs
in the Makefile. Same goes for any other source ffmpeg-0.4.8.tar.gz (we can
comment checkout, and proceed). Surely CVS version from mplayerhq.hu differs
from distribution versions.

I changed the src/Makefile command install-libs and install-headers to
install (keeping my fingers crossed), but it didn't work either :)

I am unable to understand that completely. Actually I'm not very keen to
build contrib, as it is a considerably larger build than the
"proof-of-concept" build I want.

I looked into libiconv-1.9.1/lib/.libs. There is no ".a" file. Again, I am
open to using ".so" (I would rather prefer it) but I cannot solve this:

Making all in .

So it all comes to this: How to get past this error?

Thanks for all your suggestions
