- The DJGPP Cross Compiler
- ------------------------
-
-
- 1. What is DJGPP: [from http://brennan.home.ml.org/djgpp/]
-
- DJGPP is a port of GNU GCC to the DOS environment. (It stands for
- DJ's Gnu Programming Platform, if it has to stand for something, but
- it's best left ambiguous.)
-
-
- 2. Who created/worked on DJGPP: [from http://brennan.home.ml.org/djgpp]
-
- DJGPP was done primarily by DJ Delorie. Charles W. Sandmann is another
- major contributor, and there are many others.
-
-
- 3. Using the cross compiler:
-
- a. Compile your program as normal but use "dos-gcc" rather than "gcc"
- or your regular compiler.
-
- make clean
- make CC=dos-gcc
-
- b. If the last stage in the compile was "dos-gcc -o prog ..." then you
- should find a DOS binary "prog.exe" in the current directory.
-
- c. Copy "prog.exe" to your DOS machine/directory/floppy along with
- CWSDPMI.EXE (stored with this README). If you are already using a
- DPMI server (like windows) then CWSDPMI.EXE is not required but can
- be included anyway.
-
- d. Run your program as "prog" under DOS and be amazed.
-
- e. A few functions are not supported by the DJGPP library. "dos-gcc"
- defines the symbol "GO32". Use it to mark regions of code that
- are DJGPP specific.
-
- #if ! defined (GO32)
- newSpace = mmap(0, pagesize, PROT_READ | PROT_WRITE, MAP_PRIVATE,
- devZeroFile, 0);
- #else
- newSpace = malloc(pagesize);
- #endif
-
-
- f. By default your program is allocated a fixed 256k stack. Very
- recursive programs you may require a bigger stack. Use the tool
- "dos-stubedit" to change the stack size. Type "dos-stubedit -h"
- for help.
-
-
- 4. Reading the documentation:
-
- The libc library used in DJGPP is described in "info/libc.inf".
- To read this file use the "info" program from the "texinfo"
- distribution. E.g.
-
- info -f info/libc.inf
-
