A couple of minutes hacking at my Solaris 8 (Sparc) machine during the
lunch
Here are various things I'm seeing.
1) Running anything produces:
err:dosmem:setup_dos_mem Cannot use first megabyte for
DOS address
space, please report
2) Solitaire seems to work fine.
3) Running telnet produces:
err:win32:do_relocations FATAL: Need to relocate

OK. mmap on Solaris has slightly different semantics than
mmap on Linux if an address is specified and/or MAP_FIXED is

I don't remember exactly what the difference is but IIRC on
Linux if an address is specified and

The problem is the following: if you pass MAP_FIXED to mmap(),
it *will* use this address no matter what. Especially, if there
are already *other* mappings in that range, they will just be zapped.
Yes. :-(
One possible solution would be to perform ourselves a check
whether the target

So it would appear that Solaris completely ignores the passed
address, and just sorts all mmaps() nicely together ;-)
Great :-( And what does the address space look like at startup?
Where does it allocate the main exe and the .so libraries? Maybe we

I don't think mincore is appropriate, as we must check whether there *is*
a mapping, not just whether some of its pages are actually present in
physical memory.
Sure it is. The question is did mincore return an *error* for the page
being checked (in which case nothing is mapped there)

can reserve the addresses we need like 0 and 0x0040 with a
MAP_FIXED at startup.
Well, my little test app looks like this:
Note that this is on Sparc, as I don't have access to a
Solaris/x86 box. John, does it look much different there?
