I've been putting around with Linux emulation on my FreeBSD system of
recent vintage:
nexgen: {373} uname -a
FreeBSD nexgen.hiwaay.net 2.2-STABLE FreeBSD 2.2-STABLE #0: Sun May 11
17:28:30 CDT 1997 dkelly@nexgen.hiwaay.net:/usr/src/sys/compile/NEXGEN
i386
nexgen: {374} modstat
Type Id Off Loadaddr Size Info Rev Module Name
MISC 0 0 f48ee000 0008 f48ef000 1 blank_saver_mod
EXEC 1 4 f490d000 001c f4913010 1 linux_mod
Ok, linux_mod is loaded.
nexgen: {375} Wingz
Bus error (core dumped)
nexgen: {376} grep -i linux /usr/src/sys/i386/conf/NEXGEN
options COMPAT_LINUX #some say you need both.
options LINUX_COMPAT #some say you need both.
Have tried it with and without each of the above.
nexgen: {377} scalc3
User Install required before scalc3 can be run, please wait...
Segmentation fault - core dumped
Can't find initialisation script /home/dkelly/.sd.sh, User Install must be
completed before scalc3 can be run.
Wondering if my lack of FPU is a problem?
nexgen: {378} grep -i math /usr/src/sys/i386/conf/NEXGEN
options MATH_EMULATE #Support for x87 emulation
#options GPL_MATH_EMULATE
Tried GPL_MATH_EMULATE once but cvsup started core dumping. So I went back
to the standard FreeBSD software FPU.
So, does Linux emulation require a hardware FPU?
