Sorry to ask this question on both the EMX and the DJGPP list, but I tried
gnu.gcc.help and didn't get much response.
I am not trying to start a flame war but I am soliciting serious input to
the following question:
Which GCC compiler for MSDOS should I choose: djgpp or emx.
I think both are excellent ports, but I would like to have some
comparisons.
E.g.:
1. If I read the EMX doc correctly I cannot spawn (exec) a "normal" MSDOS
program from an EMX program. Is that correct? If so, is the same true for
djgpp?
2. If you spawn a djgpp program from another one, 130KB of low memory is
used, thereby limiting the number of instances to 5. Is the same true
for emx?
3. EMX cannot run under DPMI, except when you use the RSX extender. DJGPP
programs can, but they can also run under RSX. Any [dis]advantages?
RSXWIN can run EMX programs in a normal MSWindows window. Can this also
be done with djgpp programs?
4. RSXWDK can be used to develop MSWindows programs with EMX. IS there a
similar thing for DJGPP?
5. How about mixing the two? Is there any problem with using djgpp programs
in an EMX environment or v.v.?
6. Are some programs easier to port with one or the other?
7. More?
