Libgtop and FreeBSD

[Josh Sled <jsled scam XCF Berkeley EDU>]

Sorry for the lack of word/progress on the FreeBSD port of Libgtop... 
I still have intentions to finish what I've started, unfortunately,
my computer seems to be conspiring against me.

Every time I try to run test programs [to make sure I'm getting the
data, and getting the correct data], something goes wrong.  Linking
with the KVM library [used for getting access to the kvm_* functions
which report on Kernel Virtual Memory] causes the program to do mysterious,
bad things... sometimes the output code is screwed up and doesn't see the
correct main function...  Last time I tried, the program had a bus error
on the first kvm_ call [kvm_getprocs(...)], which strangely [and
frustratingly] enough had worked before...  [this is still the case...
see below]

Either I'm doing something wrong [doubtful because of the lack of complexity
of my test programs], or FreeBSD is screwed... I can't determine which.
I've been trying to upgrade FreeBSD, but I think I'm going to have to get
more disk space before I can do that... and I don't even think that will solve
the problem, since the test program didn't seem to work on a recent-release
of FreeBSD [2.2.6 ... the current release version].

Oy vey...

More as it develops...

If anyone else expresses interest in working on the port, I do have
[somewhat] functional code... maybe they'll have more luck compiling
than I...

PS. If anyone's interested or has played with libkvm in FreeBSD,
this is what happens with the program...  it's a long shot, but maybe
someone can help me... I'd really like to use gtop, someday...
