Description:

Opened: 2003-02-17 18:24 0000

mjpegtools requires svgalib to build correctly (libvga), but there is no
explicit depend.

Reproducible: Always
Steps to Reproduce:
1. emerge unmerge svgalib
2. emerge mjpegtools
3.

Actual Results:  
compile stops when trying to link to libvga

Expected Results:  
compile should complete cleanly!

------- Comment #3 From Aron Griffis (RETIRED) 2003-02-20 11:55:33 0000 -------

The problem here is that the user has USE=svga (this is the default on x86).
sdl will use svgalib when available, and mjpegtools will use sdl.

I think that this would have worked if you did

   emerge unmerge svgalib
   emerge libsdl
   emerge mjpegtools

So we have a user error here.  You have svga in your USE but you're
trying to remove svgalib from the system.  Granted, the dep system can solve
this for you if we add the dependency to mjpegtools, but that is wrong 
because mjpegtools only needs svgalib if you also have USE=sdl.

I would like this ebuild reverted to its previous state.  There's no reason 
for this ebuild to depend directly on svgalib.  Otherwise we should update
all the other ebuilds that use sdl to also depend on svgalib (conditionally on 
USE="sdl svga").

Aron

P.S. This isn't just a gratuitous change for me.  svgalib doesn't work on 
alpha, and depending on svgalib in mjpegtools breaks mjpegtools for alpha.
