This is an adaptation of zxcc-0.5.7 for RomWBW by Wayne Warthen.
|
|
|
|
In general, this is a stripped down variant of John Elliott's zxcc package that
|
|
runs under a Windows command line (32 or 64 bit Windows), Linux, or MacOS.
|
|
This adaptation implements only the main "zxcc" command. The other programs
|
|
(zxc, zxas, zxlink, and zslibr) are not inluded here because they are fairly
|
|
specific to Hi-Tech C.
|
|
|
|
Please see http://www.seasip.info/Unix/Zxcc/ for more information on the original
|
|
version of zxcc. Also, refer to https://github.com/agn453/ZXCC which has an
|
|
updated version of the code.
|
|
|
|
The included zxcc.html documentation is from the original version, so it does not
|
|
reflect the changes made here.
|
|
|
|
To build under Open Watcom, use Build-OW.cmd. To build under Microsoft Visual C,
|
|
use Build-VC.cmd. To build under Linux or MacOS, use the Makefile.
|
|
|
|
The GPL status of everything remains in place and carries forward.

After struggling to get the entire zxcc package to build nicely using autoconf,
|
|
I finally gave up and took a much more direct approach. I have extracted just
|
|
the source files needed and created a simple batch file to build the tool. I
|
|
realize this could be done much better, but I cheated in the interest of time.
|
|
|
|
The one "real" change I made in the source code was that I modified the tool
|
|
to look for bios.bin in the same directory as the executable is in. This
|
|
just makes it much easier to set up (for me, anyway).

|
- Incorporated filename case insensitivity changes from Curt Mayer
|
|
- Incorporated fixes from Tony Nicholson at https://github.com/agn453/ZXCC
|
|
- Emulation of CP/M BDOS function 60 (call resident system extension)
|
|
should be disabled and return 0xFF in both the A and L registers.
|
|
- Change cpm_bdos_10() to return an unsigned result to avoid buffer
|
|
size being interpreted as negative.
|
|
- Fix the emulation of Z80 opcodes for IN (HL),(C) and
|
|
OUT (C),(HL) - opcodes 0xED,0x70 and 0xED,0x71 respectively.
|
|
This is noted in Fred Weigel's AM9511 arithmetic processing unit
|
|
emulation from https://github.com/ratboy666/am9511 in the howto.txt
|
|
description. NB: I have not included Fred's am9511 support at this
|
|
time into ZXCC.
|
|
- Fixed parse_to_fcb function in zxcc.c to handle parsing second automatic
|
|
FCB from command line

- Running zxcc under WSL (Windows Subsystem for Linux) was gererating output
|
|
that was correct but did not match standard Windows or Linux runs. This
|
|
turned out to be an assumption in a few places in the code that reading
|
|
into a buffer would not modify the area of the buffer that was beyond
|
|
the space required by the data being read. Under WSL, this "slack" space
|
|
was mangled. I made changes in these locations to clean up the slack
|
|
space after such reads. This fixed WSL runs to produce binary identical
|
|
output. Although only required by WSL, the changes cause no problems for
|
|
other environments and are actually correct per POSIX.

- I have attempted to sync my code up with the latest code found in Tony
|
|
Nicholson's GitHub repo at https://github.com/agn453/ZXCC. The most
|
|
significant difference in my code is that I am using the WIN32 API
|
|
for all disk I/O. Although the file tracking code is retained, I have
|
|
found this mechanism to fail insome scenarios. By using the WIN32 API
|
|
I can achieve the same file sharing attributes as Unix which makes the
|
|
file tracking mechanism optional.
