dosemu difficulties

I'm just starting to try to get things to work in dosemu over linux.
My program, compiled with Clipper 5.2e and linked with Blinker 3.2,
crashes giving a BLX286 : 1304 error complaining that it cannot use
XMS host with current memory configuration. It goes on to say:

.... needs 512k of This is a DOS extended program which requires a
minimum of a 286 processor and at least 512Kb of available DPMI, VCPI or
XMS memory to run.

I've tried editing dosemu.conf to allocate 512k of XMS but it didn't
change anything.

Has anyone on this NG any experience of dosemu and could help?

Alan, we have a humongous app (EXE is about 4.5 meg) that I have run
successfully through DOSEMU for 3+ years. The very first version I tried
worked perfectly out of the box, and now I regret the kazillion upgrades I
have built and installed over the years because I can no longer get past a
problem with dbrlock() freezing up early in the program if I use my
built-in Win98 DOS. I switched to freedos and it works fine... go figure.

Can't imagine why Blinker is complaining if you set dosemu.conf
correctly. Are you sure dosemu is pointing to that configuration file?

Also, what version of dosemu are you using and what kernel?

Alan,

In dosemu.conf there is a line that reads:

$_dpmi = (0x?????) # where ????? is some value

On my system (I'm using 1.0.2.0) I will get your error if ????? is
00000. I use 20000 and it works.

Hi Ben

I had $_dpmi set to (0x5000).

I changed it to (0x20000) as suggested but it it had no effect.
What about other settings?

Peter asked about versions:

kernel: kernel-2.6.8.1-12mdkWin4lin
(the mandrake version patched for Win4lin)

dosemu: version 1.2.2.0.
It pops up:
dosemu EMS 4.0
Freecom ver 0.82 pl 3 XMS_Swap

Freedos: kernel version 1.1.35

Regards

Alan

I thought it might help if I displayed the output from mem.

The 1st .obj in your link script should be a CLIPPER one and NOT the LIBs you
have listed.
ie LIBs should be listed after the FILES

> SEARCH BLXRATEX
> SEARCH BLXCLP52
These should come before ALL LIBs in the list - read the Blinker docs

> file video1 # uses CPMI Library
Not sure if video access routines are the same in DOS as in DOSEMUs, so that a
be where your problem getting the app to run is.

> file cld.lib # Debug library file
Suggest you don't leave this in your disributed app.

Funny, this never caused a problem while compiling, linking or operating
in any version of Windows but thanks for the tip.

Good point but I suspect that may become a secondary problem.

No. I have parallel folder with separate instructions.
