: Am I missing a lib in the link line? Wrong order?
: The code uses fprintf, putc, putch fwrite, fopen, fclose

: Installed djgpp from:
: bnu281b.zip
: djdev202.zip
: gcc281.zip
: gpp281b.zip

: Thanks for any help, clues.

1.  Try letting gpp (or gxx) do the linking: "link = gpp
    LFLAGS = 
    LFLAGS2 = " and see if it works. If it does, add "-v" to the flags
    to see how gcc handled the order of libraries.

2.  Why do you not use "-O2" for optimisation?
