Hello.
I try to compile latest VLC from git on Ubuntu 10.04 LTS by using tutorial.
I got an error while execute command ./configure
configure: error: Could not find libavcodec or libavutil. Use --disable-avcodec to ignore this error.
I add --disable-avcodec
configure: error: Could not find libswscale. Use --disable-swscale to ignore this error. Proper software scaling and some video chroma conversion will be missing.
then --disable-swscale
configure: error: Could not find libpostproc. Use --disable-postproc to ignore this error.
then --disable-postproc
checking for XCB... configure: error: Package requirements (xcb >= 1.6) were not met:

Requested 'xcb >= 1.6' but version of XCB is 1.5

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables XCB_CFLAGS
and XCB_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

so I have to execute ./configure --disable-avcodec --disable-swscale --disable-xcb --disable-postproc
How can I solve problems without disabling these features?
I had installed required libraries:
libavcodec52
libavcodec-dev
libswscale0
libswscale-dev
libpostproc51
libpostproc-dev
What value XCB_CFLAGS , XCB_LIBS should be, and where should they store (/etc/environment ??)
Content of /etc/environment:
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
PKG_CONFIG_PATH="/usr/lib/pkgconfig"
Thank you!

look at xcb.pc, the place where it's stored, the .so, i don't remember exactly what, but there is something wrong, compare to the other .pc... and try to install some xcb packages

Without XCB, VLC won't be able to output video. Without avcodec, it won't be able to decode much if anything.

As the error says, you need a more recent XCB version. The easiest way is to update to a more recent release of Ubuntu.

I installed Ubuntu 11.04.
Configuring and making VLC were done smoothly.
Thanks!

On Ubuntu 11.04 VLC compiles without any problems

which tutorial did you use?

which tutorial...

Hi
This tutorial's OK:- http://ubuntuforums.org/showthread.php?t=1398119
Choose either "development version" or release "version 1.1.11".

I was able to get past this (on 10.04) by manually building the latest version of xcb and installing to /usr/local:
All other dependencies (including xcb-proto and python-xcbgen) were installed from the ubuntu package manager.

I too am using Ubuntu 10.04 LTS. I followed jfront's instructions for installing the latest XCB from source code. I then still had the issue about libavcodec being out of date. I then added the PPA repository from the URL shown below, and then updated the libavcodec and related *-dev packages. I also had to install the xcb-proto package. After all that (which really wasn't too much effort) VLC 2.0.0 compiled and ran without problems. I tested various video formats, and they all played without problems.

fixed mine by installing:

yum install libxcb-devel.aarch64
