Comment 6 for bug 684302

Hi Florian Echtler.
Your workaround not working for me.
Ubuntu 10.10 32bit
Linux wings 2.6.35-23-generic-pae #41-Ubuntu SMP Wed Nov 24 10:35:46 UTC 2010 i686 GNU/Linux

I installed packets:
sudo apt-get install devscripts quilt quilt libraw1394-dev libdc1394-22-dev liblapack-dev python-dev swig texlive-fonts-extra texlive-latex-extra texlive-latex-recommended latex-xcolor texlive-fonts-recommended

Download sources:
apt-get source opencv

Removal patch "fix_3rdparty_build.patch" leads to an error, so I replaced it with an empty file.

debuild configured - OK.(attached)

debuild make output error:

How do you solved this problem?
