The only test that fails is this one. Fro the record here's the
text of the test:
#!./perl
if (! -x '/usr/ucb/groups') {
print "1..0\n";
exit 0;
}
print "1..1\n";
for (split(' ', $()) {
next if $seen{$_}++;
push(@gr, (getgrgid($_))[0]);
}
$gr1 = join(' ',sort @gr);
$gr2 = join(' ', sort split(' ',`groups`));
print "gr1 is <$gr1>\n";
print "gr2 is <$gr2>\n";
print +($gr1 eq $gr2) ? "ok 1\n" : "not ok 1\n";
As I read this it uses a built-in, getgrpid() to get the various
groups then uses /usr/ucb/groups to get a "system level list" and
compares the two arrays.
Now the ISI4.3(NFS+YP) version of groups graps the ypmap for groups.
Needless to say when groups.t is executed it fails. So before
I go and install I like some help analyzing the problem and perhaps
getting a soluution,even. I'm a relative neophyte at perl so
I'd prefer not to play with the internals without more information.
Ho 'bout it?

> t/op/groups.t fails Howdy- I had a problem similar to yours on a Decstation 5000. Turns out that I was compiling on a machine which did not have the group id found in the passwd file listed in the /etc/group file. As a result, the system call getgroups() and the UNIX command 'groups' gave different results, forcing that test to fail. As soon as I added an entry to /etc/group with my group, everything was peachy. The way I wound up debugging this was to a) run the command 'groups' and b) uncomment out the lines (which were commented out in my version: > print "gr1 is <$gr1>\n"; > print "gr2 is <$gr2>\n"; When they returned two different values, I knew something was fishy. Hope this helps. Peace, dNb P.S. Perhaps The Author might want to make that test a bit more robust by checking for this condition. -- David N. Blank o/ \ / \ / / \o M.I.T.

Rummaging through the include files, I found I needed to set gidtype='gid_t' I was compiling with the SysV environment. According to comments in /usr/5include/grp.h, POSIX wants one size of gid_t, and BSD wants another. I forget which is which; one is short (16 bits), the other int (32 bits). I had similar problems on Dec/Mips machines. The usual symptom of getting the size wrong is spurious/missing groups from perls builtins. Configure probably has trouble wading through the various includes and #ifdefs that specify things for the various environments. I haven't had time to do 4.003 yet, so I don't know if the hints work.

Now for some more information: My ISI is running IS68K 4.3BSD UNIX: 4.1A with nfs and "yellowpages". This, in itself, should make things easier but ISI's getgrgid(), getgroups() and /usr/ucb/groups, all seem to handle the yp maps differently hence groups.t fails. I have no source licence so fixing the primatives is out of the question. Does anyone, especially Larry, have a workaround/solution for this? I'm concerned because on my other servers (sun386is/SunOS4.0.2, sun3s/SunOS4.0.3 and sun4s/SunOS4.1.1) perl seems to compile execute correctly. Thus perl on the ISI must execute the same perl scripts as the others and produce exactly the same results, at least if I have my druthers. Any and all help gratefully accepted. ger -- G.
