[GoogleCodeExporter]

What steps will reproduce the problem?
1. Try to compile ffmpegthumbnailer
2. Confirmed on Crux (gcc 4.2.3) and Arch (gcc 4.3)

This is the output:

./configure --prefix=/usr
make

The issue doesn't seem to be affected by compiler flags.  Please let me
know if you need any more info about this -- I'm not a programmer so I
don't know what might be relevant...

Try rebuilding your jpeg library and then try to build again. Also do a make 
clean to
be sure.

Thanks for the suggestion.  I did try rebuilding libjpeg (6b version) but I get 
the
same error when building ffmpegthumbnailer (make clean and then make, it makes 
no
difference though...)  Could this have something to do with the version ffmpeg 
I have
installed or how it is configured?

I don't think so, It fails to link link against the jpeg library. Does 1.2.4 
build?

I tried 1.2.2 through 1.2.5 and they all fail with the same error.  The last 
version
I am able to build is 1.1.5.

That's because 1.1.5 doesn't support jpeg yet. I think there is something wrong 
with
the configuration of your system. Somehow it cannot find the functions in your 
jpeg
library.

It should indeed be inside extern "C", weird that I can't reproduce it on my 
system.
I'll apply the patch.

Patch works for me -- thanks for your help, both of you!
