Greetings,
I have downloaded the DJGPP package, uncompressed it all, and now,
naturally, I wish to compile a program or two. I typed in the standard
"Hello.c" program, and then typed, from the DOS prompt:
C:\DJGPP\SOURCE> gcc hello.c -o hello -v -O
What I got in response to that was the following:
CPU must be in REAL mode (not V86 mode) to run this program without VCPI.
(If you are using an EMS emulator, make sure that EMS isn't disabled)
At which point I poked around looking for some indication of what an EMS
emulator does, and where I could turn it on or off. I am trying to run
this in a DOS window under OS/2. Is this possible?
I am relatively new to the 'owning an intel box' scene, and I would like to
know what VCPI is, what EMS is (expanded memory?), what V86 mode is, and
an infinite number of other things. Are there any references available that
could help me out with this stuff? My background is with UNIX boxes at
university, and an Atari ST for home use. Now I have this lovely 486 thing,
and I am trying desperately to make it useful. Any helpful comments would
be appreciated.
