IRIX 6.5 with samba-2.0.6 and gcc.

[Wolfgang Glas]

I just report a problem that seems to be know since quite a long tiem, but is
neither reflected in the FAQ nor in the README's of the samba distribution.

The problem is that using gcc under IRIX to compile samba gives a mismatch in
calling semctl, because the structure passing conventions of gcc are not same as
the IRIX cc conventions.
(As far as I know semctl is the only function taht is used by samba, which takes
a structure as and argument and not a *pointer* to a structure!)

This results in a log file like:

  smbd version 2.0.6 started.

And my client says:
 
/home/wglas > smbclient -L fhysmsg01
Session request failed (0,0) with myname=FHYSMAL01 destname=FHYSMSG01

Your server software is being unfriendly

I did a long search in the mailing list archives, where the problem was
described. (Took me 1 hour) Also the fixes are described there:

  1) Use cc to compile samba.

or

  2) Force samba to use 'mmap' during configure, if it is compiled with gcc.

I'd very much appreciate to have either a clear statement in the README's and
the FAQ or to patch the configure procedure in order to treat gcc under IRIX in
the right way. Either print a clear error message describing the problem or
disable the sysv_shmem support, when gcc is used for compiling samba and use
mmap instead.

  Thanks very much for taking up my suggestion, samba is a great tool!
