License issues with Singular
I'm trying to learn the process on how to become a Debian maintainer
or developer (I don't even know if I'm using the right terms) because
I really want to get Singular into the Debian distribution:
Someone else has already expressed interest in packaging it, perhaps
we could package it together:
However, I think we've hit a snag with the DFSG. Although Singular
itself is GPLed, its license has a clause that individual component's
licences can override the GPL. There are two problematic licenses
(which I have only found by downloading the original source tarball).
One is the MP library, which forbids modifications for commercial
purposes, and the other is the omalloc library, which forbids
modifications by anyone who isn't one of "the copyright holders of
I have contacted the developers of the MP library, and they seem happy
to provide a more permissive license. However, I have had no such luck
contacting the author of the omalloc library, Olaf Bachmann. The only
email address for him that I have been able to find has bounced
(firstname.lastname@example.org). I have also tried to contact the
Singular developers about this issue, about a week ago, and yesterday
again, but receiving no response yet.
Any suggestions what can be done? Singular's configure scripts seem to
refuse to compile without the omalloc library. I'm getting impatient
waiting for a response from the Singular development team, which did
answer another question about usage relatively quickly.
