  Hello,

    I just joined the list.  I downloaded djgpp from a mirror in montana
    and I installed all of the files.  After a few tries, I got it to
    work,  Nice job dj.

    I know that obj-c doesn't come with it.  I noticed some guy on the
    obj-c group posted a problem with getting obj-c to run on djgpp.
    (That post inspired me to consider running djgpp again.  I didn't
     have the disk space before.)  Linux is nice, but I want to fiddle
    with low level VGA and do my own real-time exec.... So back to the
    subject... has anybody put Obj-C on djgpp without success?  If so,
    please email me, else, I will take a shot at too.

    When I installed djgpp, I tried compiling them.  The one called
    GRTASK didn't work??!?  It init my screen and that was it; no more
    of anything(blank screen).  I have a monochrome monitor installed as
    well so I took that out. (I don't know the video memory maps).  It
    still didn't work.  I have a Trident 8900C card with 1 meg of RAM, I:

    set go32= mono driver d:/djgpp/drivers/tridnt89.grd

    I have tried it with gw and gh, without mono when there was no
    mono.  I don't know what else to do.  Any suggestions? Other
    demos I could try??? 

    Finally, I am interested in fiddling with the timer interupt and
    another interupt from a board I have.  How do I install my own
    interupt routines?  Which system do they have to be under? 
    Vx86, Real, or Protected.  For example, if I installed a mod
    player module under dos...would it still run while my djgpp
    program ran?  Would it run well, or would setting up another
    interupt service under another mode give a shorter interupt
    response time?

    That rounds up all of the questions I have.  Any help would
    be great!
