Hi,
I have a linux binary that expects to link to libpam.so.0 :
$ ldd dataserver
dataserver:
libdl.so.2 => /lib/libdl.so.2 (0x2901d000)
libm.so.6 => /lib/libm.so.6 (0x29021000)
libnsl.so.1 => /lib/libnsl.so.1 (0x29043000)
libstdc++-libc6.2-2.so.3 => /usr/lib/libstdc++-libc6.2-2.so.3
(0x2905a000)
libpam.so.0 => not found
libpthread.so.0 => /lib/libpthread.so.0 (0x2909e000)
libc.so.6 => /lib/libc.so.6 (0x290b5000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x29004000)
Unfortunately there is no libpam.so anywhere under /usr/compat/linux.
Is it feasible to build a libpam.so to resolve this?
regards
Mark

Does anyone know if it is possible to run the last version of VMware
under FreeBSD 5.2.1 ?
Thank a lot for any information.

>Description:
I don't know abou the current state of mmap2 in -STABLE, but I got really pissed with the constant error output to tty.
Since the original patch by Kenneth does not apply 100% clean to RELENG_4 I made a few dirty changes to it.
Surprisingly I got an increas of roughly 70 frames running this patch and quake3-linux (timedemo 1 - four.dm_68).

I believe I also submitted a PR on this one a while back.
The cause of the problem seems to be that Linux (or at least the Redhat
Linux executable binaries used by most of the Linux emulation ports)
uses the ELF OS ABI code assigned for SYSV (which happens to be zero)
and not the code assigned for LINUX. Perhaps Linux ELF executables are
simply not branded by default.
(See the symbols ELFOSABI* defined in /usr/include/sys/elf_common.h.)
I won't speculate as to whose "fault" this is. The upshot is that if
you have enabled both the SVR4 and LINUX emulators, FreeBSD may choose
the wrong emulator some of the time. I vaguely recall that there is
a sysctl variable that can establish a default brand other than zero.
I don't see how this can help if you have both Linux and SVR4 binaries
on your system.
Since I didn't actually have any SVR4 binaries to run at the time, my
workaround was simply to disable the SVR4 emulator. I think I recently
read in one of the FreeBSD mailing lists that SVR4 emulation is scheduled
for the scrap heap since nobody seems to be using it. Perhaps this is
one reason why.
Perhaps the Linux emulator ports should rebrand all Linux ELF files
before installing them.

Hi, I'm having two little problems with the VMware3 port.
-The first problem is with the mouse, giving this message:
unsupported host mouse type "sysmouse"
I have the mouse set to autodetect.
-The second problem is with the cdrom drive, giving this message:
VMware Workstation was unable to read from file /dev/acd1. This can be
caused by a Linux kernel bug and will prevent your guest operating
system from properly accessing the CD-ROM drive. The kernels which are
known to exhibit this problem are 2.2.16-3 and 2.2.16-22. Please see
the http://www.vmware.com/support/reference/common/cdrom_guest.html
web page for more information on workarounds.
I have the cdrom drive set to /dev/acd1. Acd0 is my first drive, but
I'm using acd1 for vmware.
I'm wondering if the second problem has to do with me using
linux_base. I see that there is also a linux_base-8 port as well. I
have the linux_base port installed. Let me know what you think.
Thanks.
