Hi all

Currently I compiled VLC for streaming , ... compile and VLC streaming is OK.
Kernel : Linux 2.6.9-34.EL
Distribution : Redhat EL 4
Compile folder: /usr/local/src
VLC and x264 : current version which I downloaded from SVN server.
-----------

But I have 2 problems during the compile. Please advise/help me my problems.

1. I could not compile with x264 encoder. Without to include x264 tree, I can compile.
I did configure with "enable-x264" and "--with-x264-tree" option.
I compiled current version of x264 in the "extras" of vlc main folder.
But I had following error messega:

2. I got warning message on "avahi-client". I did "--disable-avahi-client", but I got still warning message.
What is the avahi-client ? how can I disable it in my confugure.

=========
checking for avahi-client >= 0.3... Package avahi-client was not found in the pkg-config search path.
Perhaps you should add the directory containing `avahi-client.pc'
to the PKG_CONFIG_PATH environment variable
No package 'avahi-client' found
configure: WARNING: avahi-client library not found
==========

there is something wrong since the config test tries to link with the system libx264, not the one in the tree you specified

--disable-avahi-client doesn't exist, you should use --disable-bonjour (avahi client is used only by bonjour module)

funman: Thank you very much for message

1. When I installed x264 from RPM package and then I deleted "--with-x264-tree" (only --enable-x264) from configure, ... I had not error message again.
2. I did "--disable-bonjour " in configure, ... I had not warning message again.

Hi,

Some other people have reported the same problem i.e. configure not passing the good location of libx264 when trying to compile it. but i've just try with the current svn and it works ok here.

could you try the following patch, re-bootstrap and report the content of foo.bar

Thank u, xtophe

I am going to try it tomorrow, ...

I have had the same problem, which can be summarised as follows:

• - Building VLC from svn following the instructions on this page (although I'm using a slightly different set of ./configure options) http://www.jbkempf.com/blog/post/2007/0 ... Feisty-704

• - when trying to ./configure I get the error "The specified tree has not been compiled" (referring to x264) even though I have definitely compiled the source

• - if I remove the --with-x264-tree=../extras/x264 from the ./configure options, vlc will configure, compile and run.

However! There are still further problems... Although VLC will build using this work-around, it fails to install - although it can be run from inside the build directory... This is really inconvenient and tends to cause knock-on problems.
I got around the problem by using known-good svn revisions of vlc, x264 and ffmpeg (i.e. versions that I had compiled previously with no problems). These were as follows:

• vlc revision 24091

• x264 revision 715

• ffmpeg revision 11410

This configures, builds and installs without issues. Not a proper solution, I admit - haven't worked out what the issue was with the latest svn revision - but at least I have a version that works!

After debugging the makefile, I found that the PKG_CONFIG_PATH does not get set for x264 in the config.

so, set it before the ./configure- eg:

export PKG_CONFIG_PATH=`pwd`/extras/x264


This will just fall back to whatever version of x264 that's installed on your system. Very annoying. Hopefully this fixes my buffer underflow problem with h264.
