  Hello,

    As of 1.11 or 1.11m or 2.5.7 GCC, the objective C library distributed
    with DJGPP has not worked.  The adding of encoding.c was necessary,
    but the runtime would come up with strange errors when compiled.  I
    think it is due to optimization within gcc for the i386.

    In order to get Objective C working with DJGPP, the library will
    have to have the _optimization_turned_off_.  I was working on the
    problem to figure out why this isn't working, but I need to get
    all of GCC sources before I do that and report to the gcc group.
    Also, I didn't check the other levels of optimization yet, I just
    know that without optimization on the runtime, the code will run.

    Hope that helps,

  Dru

P.S. dj:
Here is a small piece of code which could be added to the tests to insure
that the obj-c potion is working.  It should say "My class is Object".
To compile just do a gcc -o obtest obtest.m -lobjc.


#include "objc/Object.h"

main() {

 id test;

 test = [Object new];

 printf("My class is %s\n", [test name]);


}
