is it ok to reply to these msgs and discuss these issues on the list?

well, they actually are. i was compiling mythtv on an amd64 system,
and ran into problems with incompatible ioctls.

it turned out that i redefined the long-long in the pvr150/500 driver
to 32bits already, because non-64bits-freebsd's don't accept 64-bits
operations in the kernel.

so i had a driver <-> userland mismatch. i went with the lowest common
denominator ( ie: 32bits )

it does, but currently the pvr150/500 driver does not support it,
although i seem to have implemented it. i need to look at that later,
it is my intention to make select work for the freebsd-driver. but in
the meantime this should work for people who want to run mythtv on

well, that's a good question. i don't know either. but
mythbackend<->mythfrontend communication only works when these locks
are disabled. otherwise commands timeout and nothing happens ( this is
the patch that took me a real long time to find ). this is the problem
most freebsd people encountered but couldn't solve.

malloc.h is deprecated on FreeBSD. do i need to resubmit the patch
with this changed?

fails to compile otherwise.

i will need to look it up. is it in the same file?

why is this better?

command fails. doesn't produce version.cpp, build fails.

no problem at all, i am happy to explain the patches.
