Hi,
Ok, I can give it a go, but how would I go about doing that? Could you give me
some pointers, such as were to look and how to get a log? The current build is
using the following, should I enable additional options to get more information?
./configure --disable-png --disable-jpeg --disable-freetype
--with-gfxdrivers=savage
Thanks for your help, I am happy to do the work, I just need to a little help
about how to go about it and what to look for.
Regards
Tim
