Bug 288467 – media-video/ffmpeg-0.5-r1: manpages are not installed

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Arthur D. 2009-10-10 18:25:27 UTC]

I found that I cannot find any help on using ffmpeg from installed documentation.

But I remember there were man pages for ffmpeg and ffserver in my previous "distro" which was LFS.

The man pages can be installed successfully using instructions from BLFS:
http://www.linuxfromscratch.org/blfs/view/svn/multimedia/ffmpeg.html

This line should be in interest of you (probably you want to adapt it to Gentoo):
texi2html --version >/dev/null 2>&1 || make install-man

Reproducible: Always

Steps to Reproduce:
1. emerge ffmpeg
2. man ffmpeg

Actual Results:  
No manpage found

Expected Results:  
:)

Did you try to emerge ffmpeg with the "doc" USE flag being enabled? That way I got man pages for ffmpeg and ffplay.

That's right. They are installed with "doc" USE flag.
But there's extra dependency (texi2html). Which is excessive.

Shouldn't man pages be installed by default, without "doc" USE flag?

[Comment 3 Arthur D. 2009-10-11 16:37:43 UTC]

I think "doc" USE flag should be used only when the user wants to have API documentation built or some extra docs.

[Comment 4 Lars Wendler (Polynomial-C) (RETIRED) 2009-10-12 08:14:50 UTC]

This is an upstream issue since they coupled the man-page creation with creation of the other docs.

[Comment 5 Arthur D. 2009-10-12 09:46:23 UTC]

That's not an issue for upstream. They made man pages to be installed with:
"make install-man"

The man pages should be installed explicitly if "doc" USE flag is not used and app-text/texi2html is not installed. That's the meaning of the command from LFS instructions I mentioned above.:
texi2html --version >/dev/null 2>&1 || make install-man

Let's se what our video maintainers think about this patch.

No need to CC yourself when you're the reporter of a bug.

Thanks, I'm so n00b :-)
Is there any progress on the bug?..

[Comment 9 Dror Levin (RETIRED) 2010-01-26 15:56:03 UTC]

There's no need for texi2man to install the manpages, so it now always installs them. Fixed in 0.5_p20601-r1 and 9999-r1, thanks for reporting :)
