Bug#819402: mono: dllmap for non-linux arches

Package: src:mono
Version: 3.2.8+dfsg-10
Severity: normal
Tags: patch
User: debian-bsd@lists.debian.org
Usertags: kfreebsd


In mono-config(5) files, dllmap can be limited to a specific platform
such as os="linux".  Currently, GNU/kFreeBSD is (and someday Hurd will
be) defined as os="unknownOS", and so ignores those mappings.

DLL mappings marked as os="linux" seem totally appropriate for
GNU/kFreeBSD, or any other Debian system (whereas those marked
os="freebsd" are typicaly not).

So in this context, "os" does not determine kernel-specific
functionality to use;  just the naming of system libraries.

It seems best to interpret os="linux" as referring to any GNU
libc-based platform.  Please consider the attached patch to do

I tested on kfreebsd-amd64 where this change fixes a Mono application
(OpenRA) to work seamlessly.

Thank you.

For the purposes of mono-config(5), let GNU libc-based platforms such
as GNU/kFreeBSD or Hurd be matched by os="linux" (rather than

dllmap entries for os="linux" are appropriate for those platforms.
