Or do a diff between the two > tarballs. I tried to use svn-bisect but failed, since I did not know how to use it encountering compile error for a revision. Thus, I did it manually, but could not reproduce the error. While webcamd from svn always works with kaffeine, webcamd from ports still fails. I did this in a clean directory: setenv HAVE_HAL YES tar xvjf /usr/ports/distfiles/webcamd-0.1.24.tar.bz2 cd webcamd-0.1.24/patches/ ./do_patch.sh cd .. make ./webcamd -d 0.7 -H #kaffeine hangs tuning cd .. svn --username anonsvn --password anonsvn checkout -r 1786 svn://svn.turbocat.net/i4b/trunk/usbcam/ulinux cd ulinux && make fetch && cd patches/ && ./do_patch.sh && cd .. && make -j3 all ./webcamd -d 0.7 -H #kaffeine works fine cd .. rm -fR ulinux/ svn --username anonsvn --password anonsvn checkout svn://svn.turbocat.net/i4b/trunk/usbcam/ulinux #Checked out revision 1797 cd ulinux && make fetch && cd patches/ && ./do_patch.sh && cd .. && make -j3 all ./webcamd -d 0.7 -H #kaffeine works fine What is the difference between webcamd-0.1.24.tar.bz2 and r1786 from svn? Or is http://www.selasky.org/hans_petter/video4bsd/index.html outdated and webcamd from svn should be build differently? Thanks, Jan Henrik
