>From NT 4.00.1381, DJGPP Make 3.78.1 calls the compiler, and the compiler calls the >linker, and an illegal exception occurs. Error [35]: General Protection Fault in LD21K.EXE at 00C7:2746 code=0200 ss=017F ds=0377 es=0257 ax=5B6F bx=5B6E cx=0003 dx=0257 sp=0FF4 bp=628E si=0008 di=0028 The pop-up error is: C:\WINNT\System32\CMD.exe - make The NTVDM CPU has encountered an illegal instruction. CS:d100 IP:0fa8 OP:f2 8e 0a 15 e3 It happens every time. When I use Greg Yachuk's Make (40k), it works okay. Purhaps a different shell is being used or there isn't enough memory since it is 198k. Mem /c says: Total bytes available to programs (Conventional+Upper) : 720416 (703.5K) Largest executable program size : 618512 (604.0K) Largest available upper memory block : 96320 ( 94.1K) I'd like to use DJGPP's make because Yachuk's Make has a command line length limitation. -- Dennis W.
