Bug 14857 – emerge transcode-0.6.3.20030116 fails with `ld: cannot find -lvga`

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Ewan Mac Mahon 2003-01-31 11:20:22 UTC]

User-Agent:       
Build Identifier: 

I'm running gentoo 1.2 unstable, kept up to date with emege --update world 
(note not with --deep), and emerging transcode fails at the line with  
'ld: cannot find -lvga'.  
 
There is indeed no libvga.a/.so but I can't see why it would want it. 
I've tried emerging with: 
USE="-sdl -mmx -mpeg -sse -dvd -encode -X -quicktime -avi" emerge --update 
transcode 
in an attempt to narrow the problem down but exactly the same error occurs. 

Reproducible: Always

try emerge svgalib
then try again emerge transcode

[Comment 3 Jonas Berlin 2003-01-31 18:00:14 UTC]

Essentially transcode does not depend on libvga (svgalib). But it might depend on a library that depends on libvga. For me, it was libdv that had been compiled a long time ago while I still had svgalib installed and in USE. Thus, when I uninstalled svgalib and removed it from USE, I unintentionally broke libdv.

To find out which of your installed "libtool" libraries depend on libvga, do:

 grep -- -lvga /usr/lib/*.la

You can then re-merge the packages owning these libraries. I re-merged libdv (0.98) and after that transcode emerged just fine.

* Suggestion: change this bug to resolved and create new bug to fix the libdv (at least 0.98) ebuild to include a conditional dependency on svgalib, perhaps something like:

  svga? (media-libs/svgalib)

.. although not having looked at libdv's configure scripts I can't say for sure..

Bingo, it was indeed libdv; I can see I'm going to have to read up on libtool. 
The libdv ebuild doesn't show a dependency on svgalib, and it seems slightly 
broken with respect to xv too. I shall have a fiddle with it and submit a new 
bug when I think I understand it properly. 
 
Anyway, we can consider this one resolved / not really a bug - thanks.

sorry for this

[Comment 6 Martin Holzer (RETIRED) 2003-02-24 14:53:23 UTC]

reemerging libdv/svgalib fixed this
