Foxpro in RH9

Foxpro in RH9

[Marek Kriz]

Hi!

In RH9 with Dosemu 1.1.4.15 when starting Foxpro 2.6a (under DRDOS 7.03)
I am getting SIGSEGV. In previous RH8 wasn't such problem. XMS is OFF,
EMS is OFF, DPMI is 8192, DOSMEM is 640. How can I determine where is
the problem?

Bye, M

  Try DOSMEM=ON in config.fp (FoxPro config).

Same result as before. SIGSEGV. Can I help with some -DEBUG output? And 
what?

Thanks, bye, M

Why are you disabling EMS and XMS and
setting the DPMI so low?

Hmm, because you've explicitly stated
that the problem didn't happen in RH8,
I would think configuring the dos soft
just as well as the dosemu itself may
be futile.
I've heard about some problems with nptl.
Even though this is a wild guess, try
this:
export LD_ASSUME_KERNEL=2.2.5
It helps wine under RH9, so maybe it can
help also dosemu?
However, does any other DPMI program
work? Can you just run dos4gw? Or is the
DPMI subsystem is completely non-functional
under RH9?
What kernel is there? Can you try the
fresh 2.4.20 and see if it helps?

Because for DOS FoxPro is it enough.

Yes, it helps! DPMI is back. 
Tested also with new 1.1.5.0 (and 1.1.4.15).

2.4.20-18.9 = last from RedHat updates.

Any more tests are needed?


Thanks, bye, M

Very bad... That means we are NPTL-incompatible
for some reasons.

Yes, *fresh* 2.4.21 would be a good test-case
if compilling the kernel doesn't hurt you too
much.

Another interesting test would be to change
#ifdef __linux__
to
#if 0
in dpmi.c, line 24
recompile and see if probably this also fixes
the problem.
