Well, Fedora 8 doesn't have /etc/sysctl.d/wine.conf, so Fedora 8/yum
evidently didn't set it. I created a file:

===========/etc/sysctl.d/wine.conf================ 
vm.mmap_min_addr = 0
==================================================

This has had no effect. I'm still just seeing:

$ wine setup.exe
err:dosmem:load_winedos Could not load winedos.dll, DOS subsystem
unavailable
winevdm: unable to exec 'D:\ewview3.08.2\one\setup.exe': DOS support
unavailable

Since DOS support *is* apparently available in the form of 

/usr/lib/wine/winedos.dll.so

why can't wine find it? A related program, the EW logfile uploader, a
graphical Win95 programs runs successfully.

I tried running wineconsole with the same result. I also tried and
winedbg, which initially showed:

0x60419652:movl	%esi,0x0(%esp)

which I assume is expected. Typing 'cont' produced:

First chance exception: page fault on write access to 0x00010400 in
32-bit code (0x601de3d7).

Entering 'cont' a few times merely repeated the error and stack dump.
'quit' exits and reports:

$ err:dosmem:load_winedos Could not load winedos.dll, DOS subsystem
unavailable
winevdm: unable to exec 'D:\ewview3.08.2\one\setup.exe': DOS support
unavailable
 

All this means very little to me since I don't know wine's internals.
Does it mean anything more to someone who does understand the innards?

As I said, this is wine-1.1.9 - the latest version in the Fedora 8
repository. WINE release notes don't mention this problem, so presumably
upgrading to a later version would not help.


Thanks,
