Hello!
I want you to know that I recently made a 32 bit development system for DOS,
based on the well known LCC compiler (version 4.2). This system works under
pure DOS systems and uses NASM 0.98 to produce COFF assembler code. This
code is linked with the LD linker from DJGPP. The C library from GCC can be
used with this compiler system. I also manged the main porting of the header
files. You may use the internal precompiler or the one DJGPP uses.
This way, you can use LCC as a very good and fast replacement for GCC under
DOS. The system comes with full source codes. Every binary, used in this
development system can be compiled with DJGPP 2.01..2.03. The compiler
proper compiles itself.
I also developed a VESA graphic library (protexted mode) for high resolution
graphics. Some years ago, I posted a 16 bit assembler version for the
PACIFIC C compiler to the freedos project (which can be found under the name
VSALIB 1.4 in the libraries archive). The new library has much more
facilities as the older one: Macintosh screen fonts (ported by me to DOS) as
well as Macintosh icons. You can draw quadratic or cubic bezier curves with
a very fast incremental algorithm (explained in separate docs). You can also
use the mouse in your graphic programs. There are many example programs,
which explain the use of the library.
Perhaps you are interested in this nice self containing development
environment. I also contacted the makers off LCC at Princeton and they
welcomed this particular DOS project. I think, LCC for DOS has the ability
to get a real alternative to the much larger DJGPP development system.
Please reply, if you are interested and if so, please tell me how to send
the LCC project to the freedos developers for testing purposes.
Thanks for your interest,
Detlef Reimers, Kaltenkirchen (Germany)
