I trying to re-compile a very, very, very old Project written for the Archimedes Compiler Version 4. It was created by an employee that is no longer with the company. The Target CPU is a Siemens 80535, an enhanced 8051 CPU, and a single 27C512 EPROM. When I run the MAKE File it calls C:\arch4\bin\c-51 (an .EXE file dated 11/14/1990!). I am trying to compile in a DOS window in Windows 2000. I am told that the orignal programmer used a DOS window in Windows 3.0 for compiling. Any help in how to prevent the "DOS/16M Error: [30] Program must be built -AUTO for DPMI" ERROR Message? This Embedded application has no idea what DOS/16M or DPMI is and could never use that functionality.
Andy, Yes, you are correct, it is the COMMAND.COM file. I remember that file from the old DOS days (Command.com, Autoexec.bat, Config.sys) I never thought I would be compiling a program using command.com in the year 2003! :-) Yes, CMD.EXE and COMMAND.COM are different enough to cause the C-51 compiler to work on one but not the other. I didn't even know command.com was hiding in c:\winnt\system32\ sub-dir on my Windows 2000 computer. It makes a MS-DOS Icon while CMD.exe makes a C:_\ Icon shortcut. I learn something new every day. I can also get the Compiler to run under cmd.exe if I use this "command /c c-51 ..." I am so happy that it works! Greg
