Reply-To: kagel AT dg1 DOT bloomberg DOT com Date: Wed, 05 Feb 1997 10:24:54 -0600 (CST) From: "Mr. Fuju" Hi guys and gals! I am currently getting the djgpp package on my computer so that I can use it, but I want to know a little about what I'm getting myself into here... How different is programming with djgpp from programming in C++ using Turbo C++ for DOS or g++ for Unix? Exactly what is DPMI and where do I find information on using it? Will my other C++ programs that I've written compile under djgpp? If these questions are addressed in the FAQ that I've not read yet, just tell me so and I won't Much of this is addressed in the FAQ. Basically your UNIX programs SHOULD compile and run as expected with few exceptions. TC++ programs will normally contain many DOSisms and 16BITisms that will need to be recorded. Also any embedded assembler code and assembler modules will need to be recoded to AT&T assembler syntax and rewritten to use 32bit instructions and registers. Also since much assembler is written to access hardware addresses and ports this will all have to be recoded to access things in 32 bit protected mode. Again the details are in the FAQ. bug you anymore before I read it... Oh, and what about support? Obviously this mailing list is available (thankfully), but are there any other sources of information for difficulties with programming with djgpp? Also, I'm running Windows NT This is the best place. Also you can scan the newgroup/mail archive on DJ's server before posting, if the FAQ does not cover it, because many questions have been answered before but may not have made the FAQ yet.
