Subject: DJGPP Under OS/2 Warp

    Thank to those who pointed out that GASnnnBN.ZIP is no longer a
separate package. I have installed what I think are all the packages
need to compile and run C++ on my OS/2 Warp system at home. I have had
many problems, so I will begin by listing everything I installed.

    lgp262bin.zip
    lgp262dc.zip
    bnu252.zip
    gcc263bn.zip
    gcc263rm.zip (the 2/1/95 version)
    gpp263bn.zip
    djdev112.zip
    djdoc112.zip
    djeoe112.zip
    txi310bn.zip

    After all of those were unzipped under a directory called djgpp, I
unzipped each of the four dj112m?.zip files, executing 112m?.bat after
each one. Each of the bat files produced errors. (I executed them
under DOS.) The first one could not find:

    LIBSRC\C\SYS\STAT_AST.S and LIBSRC\C\SYS\GETTIMEO.S

    All four of them produced the following error once or twice:

SYS3088: The name AR is not recognozed as an internal
or external command, an operable program, or a batch file.

    Each of them told me I could remove the objs and p_objs
directories, but there is no p_objs directory.

-------

    The file djgpp.env seemed to have more than I needed so I created
an OS/2 .CMD file from it. I omitted the OBJC_ and OBJCPLUS_ includes.
I also noticed that the subdirectory djgpp\include\sys was not listed
so I added it to C_INCLUDE_PATH.

    I could not compile under OS/2. Both GO32 and GCC wanted to be run
under DOS. I am also confused by the fact that I have another version
of GCC. I had previously installed GNAT Ada (from cs.nyu.edu) and it
works well under OS/2. Can I use that OS/2 version of GCC instead of
the GCC that I got from oak.oakland.edu? If so, can I remove GO32?
What other changes would I need?

    I have not gotten my simple C++ program to compile successfully
yet. The closest I got was pointing to the GCC that came from oak, in
what I think is a post-compile link, told me it could not find crt0.o
which I could not find mentioned in my program. Also, its result was a
file named for my program with no suffix.

-------

    I hope someone can help me with some of my confusion.
