I've recently installed Caldera OpenDOS and tried DJGPP V2.0. I thought that it would be nice if one could compile things in the background while editing some text in the foreground. The problem is that if one uses DPMI=ON with the EMM386 that comes with OpenDOS gcc and other programs crashes. EMM386 complains about protection fault (or whatever) and one has to reset the computer. If one uses DPMI=OFF with EMM386 the computer doesn't crash. It is possible to switch between tasks, but gcc doesn't run in the background. At first I thought that the multitasking didn't work at all but I used an old basic compiler (only 8086 code) and wrote a small program that just counted up a variable and printed it's value to the screen. Then I put that task in the background and it continued to run (horribly slow but still...). This could be changed in \OPENDOS\TASKMGR.INI so that background processes got more time and it ran faster. However, gcc still doesn't run in the background. Has anyone succeded in getting gcc running in the background? /Daniel
