Hi there,
I would really like to see POL running natively on my OpenBSD-Systems.
But I don't think that'll happen soon, so I did some research.
Working POL Versions: any statically linked linux-version up to pol-linuxbin-096-2005-03-05-gentoo.tar.gz - these work without any problems, since they were built with Linux Kernel 2.0.0 (at least the Binary format is compatible to 2.0.0).
The next version, 2005-04-04, doesn't work any more, and so do any following versions. The reason is the following: Because it is built as a Kernel 2.4.1 Binary, it tries to use NTPL, because it thinks it's running on a Linux Kernel > 2.5 (it calles uname and OpenBSD says it's 4.0). This causes it to try do a syscall linux_sys_set_thread_area, which isn't implemented in the Linux emulation of OpenBSD.
One way to fix it would be to recompile POL to not use NTPL... I can't do that, don't have the source. If you would provide a binary I would be happy
Another way to fix it would be to fix the Linux emulation in OpenBSD... That would be great, but it would be very difficult as I'm not familiar enough with the code.
Third, I could use the FreeBSD binaries, as OpenBSD also has an emulation for FreeBSD. This is not possible, because the FreeBSD binaries of POL are compiled for version 6.1, and OpenBSD only supports up to 5.0 (not shure here).
I'm still researching, but if anybody could give me some hints what to do next to try getting POL working, please contact me.
Regards,
oenone
