- Anyone out there with experience in porting UNIX/X11 applications to
- MSDOS?
-
- We are investigating the possibility of porting a rather big UNIX/X11
- application (about 25 Mb source) written in FORTRAN and C to MSDOS.
- The reason we want to port to MSDOS is that a lot of people have a PC
- that is adequate for our application, but the do not want to leave
- MSDOS becouse of existing applications, or they do not want to learn
- a new OS like for example UNIX.
-
- What dit you do about the following problems:
- - Limited file name lengths
- The development will continue on UNIX, so for sources i would not mind
- to convert file names automatically.
- - Memory - UNIX has an "unlimited" virtual memory space for every proces
- Are there compilers or other methods to have an "unlimited" address
- space under MSDOS (or maybe Windows NT) ?
- - Can linkers under MSDOS handle long routine names
- Our routines are unique within 9 characters.
- - Can you combine C and FORTRAN code the same way you do under UNIX
- i.e. trailing underscore and extra parameters for stringlenths for
- FORTRAN routines
- Note: we could prevent the problem of combinig C and FORTRAN by converting
- our FORTRAN code to C using F2C.
- - What dit you do about graphics, we currently use X11
-
- Other things I would like to know are:
- - What compilers and utilities dit you use
- - Where can they be obtained (reps in The Netherlands or elsewhere in Europe)
- _ What was the approximate cost
-
- Are there any problems i dit not mention that i should think of?
