samba - Nov 1997 - Linux mmap() Problem

I'm new to the list so this may be old business.  I suspect it is.

I got the samba (1.9.17p4) sources and compiled everything on Linux
kernal version 1.2.13 from Yggdrasil.

The compile went fine, but the smbd got a runtime error from the
mmap call in shmem.c.  Closer examination revealed the mmap() function
appears not to work at all on this system.

I got around the problem by allocating a shared memory segment and
mapping the SHARE_MEM_FILE into it, but I'm sure this isn't what
the authors had in mind.

Anybody know what I'm doing wrong?

TIA

You are using a very old by now version of Linux. You should seriously
consider upgrading to a system which uses kernel version 2.0.x. Otherwise,
do not use MMAP - I think there is a compile option to turn it off.

Using Linux 2.0.x and mmap() will give you better performance if that is
an issue.
