Hi,
I'm trying to get some development tools running under dosemu, which includes
the Borland C/C++ compiler and debugger, and a program called loc31.exe, which
is a code locater. The compiler and the debugger seem to work fine (they come
up on the screen without squawking), but the loc31.exe program crashes.
Normally, just running 'loc31' under DOS generates a usage message, but under
dosemu, it generates the following:
32loader runtime error: Unhandled exception
Exception 0D at 00D7:0008E221 error code 00000000
CS=00D7 DS=00DF ES=00DF SS=00DF FS=00FF GS=0000
EAX=00000000 EBX=00000000 ECX=0002A000 EDX=000F5FF8
EBP=000F5FEC ESP=000F5FD8 EDI=00027000 ESI=00000000
The invalid instruction was executed at 0008E221
Module 'C:\TERN\BIN\LOC31.EXE' section 'CODE' offset 00054221
[0008E219]: 43 0C 99 41 46 00 EB 54 - 80 3D 58 00 47 00 00 74
loc31.exe requires a number of DPMI programs: 31rtm.exe, dpmi32vm.ovl, and
dpmiload.exe, which are in the path.
I'm running RH 6.0 with the out-of-the-box kernel, 2.2.5-15. I've installed the
latest stable version of dosemu from the rpm on the www.dosemu.org site
(0.98.8).
I have tried both bootdir and hdimage configurations, running the loc31 program
from a floppy or the harddrive without luck. I've tried the FreeDOS included
with the dosemu, DOS 6.0, and the DOS from Windoze98. I've included the
dosemu.conf file below. I thought I would check with this list before spinning
my wheels any farther (I looked through the list archive, but didn't see
anything appropriate - I may have missed it, though).
Any help/suggestions would be appreciated. Thanks.
