Re: [N8VEM-S100:2245] a GOOD C Compiler for the Z80?

Hello John,
What is the problem with SDCC 3.3?
I'm using it with my CP/M coding experiments here https://github.com/hkzlab/sdcc-cpm-example/tree/master, and it is (apparently) working.
My compiled code executes on the SBC V2...

SDCC for the Z80 installs and runs both under Linux and Windows for me.
I have used it both places. One tip: the newest release is impossible
to use. Use release 3.0.0, not 3.3.0. One thing about SDCC, is
specifying the "machine" every time. Every compile line needs "-mz80"
on it, otherwise it produces code for the 8051. This requirement is
best handled through a Makefile. SDCC has no 'make' facility itself,
but I use NMAKE under Windows from an old release of Micro$oft-C.
WMAKE, from Watcom (below) is also a good 'make' facility. One negative
about SDCC is that the assembler, SDASZ80, uses a syntax that is not
compatible with TASM; but it does produce relocatable modules. Further,
there is a library facility.

Keep trying to get SDCC working; it is the compiler of choice, in my
opinion, for Z80/Z180.

For the 80386, there are several flavors of Open Watcom. This is what
was used for the SBC-188. I think you can install versions that will
produce real-mode code (8086/8 or 80186/8) or protected mode 32-bit
code. It is best to run it under Windows in all cases. A good bit of
SBC-188 BIOS code is written with Watcom-C. I don't use the version
that produces 32-bit code. The SBC-188 uses NASM for the assembly code,
making all the tools to create the BIOS open source, hence, free.

DJDeLorie's port of GCC to extended DOS is good for writing 32-bit code
to run under DOS or Windows. For DOS, a 32-bit free extender is
included. The compiler is sometimes known as DJGPP. There is a whole
library of U**x utilities available for DOS/Win. It is not quite up to
the latest GCC release, but great if you want to run 32-bit code from a
DOS box. It is huge, and a bit of a bear to install, but well worth the
trouble.
