Problem compiling extras/contrib/libgcrypt on ubuntu 8.04

[davidoff]

Hi,

The latest supported VLC on 8.04 is 0.8.6 which is quite old, so I set forth to compile VLC.
apt-get build-dep vlc is of no help for the same reason as above, so I want to compile contrib/extras.

I had to add --enable-nonfree configure option to contrib/src/Makefile in the ffmpeg target (supposedly because of --enable-libfaac), I'm not sure this was the right way.

Everything almost works in extras/contrib, but when I get to libgcrypt, it fails in the tests target (below is the tail of the build output):

I don't know what to do to resolve this, nm libgpg-error.a shows that gpg_strerror is present.

Can someone help me ? Thanks alot.

No, no, and no.

Do NOT compile contribs on Ubuntu.

Serious, read my blog and search for ubunutu.

OK, I've done what you suggest. But I am affraid there is nothing to do:

when following steps at your blog, the configure step fails with a glib incompatibility test:
...
configure: error: Buggy GNU/libc (version 2.5 - 2.7) present. VLC would crash; there is no viable work-around for this....

As I see things, updating glib is not a simple thing, and I am sure the Ubuntu guys are not wanting to update the core library.

Modify configure.ac to go around it.
Moreover, I would advise to take VLC 1.0.0-rc1 from upstream.
