ffmpeg slackbuilds.org script failure
 
Hey all,

When I try to compile ffmpeg for Slackware 13.1 x86_64 using the slackbuilds.org script, I have to comment these lines:

Code:
( cd $PKG/usr/man
  find . -type f -exec gzip -9 {} \;
  for i in $(find . -type l) ; do ln -s $(readlink $i).gz $i.gz ; rm $i ; done
)
If I don't comment them, the builds fails with this error:

Code:
./ffmpeg.SlackBuild: line 194: cd: /tmp/SBo/package-ffmpeg/usr/man: No such file or directory
:)

It is not the script's fault.
You probably ran "su" to become root in order to compile the package. However, this does not provide a fully compatible root shell... your environment is incomplete.

If you use "su -" to become root instead, then you will have root's full shell environment, so that the ffmpeg.SlackBuild script will work correctly (and the man pages will be created).

Are you using su or su - ?

Use "su -", according to slackBuilds guidelines.

Edit: Oops sorry, too slow here :D

Actually I did this:

$ kdesu "konsole -e $SHELL -l"

Or rather I have that as a shortcut on my main KDE panel. I thought the -l option made sure I had a complete environment.

I've just tried compiling it again, this time using "su - root". The result:

Code:
./ffmpeg.SlackBuild: line 194: cd: /tmp/SBo/package-ffmpeg/usr/man: No such file or directory

In that case, you have probably not installed the TeX package. That is required to build the man pages. A full installation of Slackware should provide it.

I was a frequent offender of the incorrect use of 'su' instead of 'su -' when using slackbuild scripts in the past. Before I corrected myself of this habit I used the following in my own FFmpeg build, which I stole from alienBOB some time ago:

Code:
if ! $(which texi2html 2>/dev/null) ; then
  export PATH=$PATH:/usr/share/texmf/bin
fi
But of course the use of 'su -' is the more correct usage :).

That was it. I had installed texlive, but for some odd reason that didn't work.

After having reinstalled tetex, the ffmpeg package now builds without error.

Thanks. :)
