ZX Command



An adaptation of zxcc-0.5.6 by Wayne Warthen



This directory contains the source files used to build the "zx" tool.  This tool

is essentially just John Elliott's zxcc package version zxcc-0.5.6 modified to

build for Windows and simplified down to just a single command (zx)

which is essentially just the zxcc command.



Please see http://www.seasip.info/Unix/Zxcc/ for more information on zxcc.



To build under Open Watcom or Microsoft Visual C++, use the following command:



  cl /Fe"zx.exe" zx.c cpmdrv.c cpmglob.c cpmparse.c cpmredir.c drdos.c util.c xlt.c zxbdos.c zxcbdos.c zxdbdos.c z80.c dirent.c



To build a debug version, use the following command:



  cl /DDEBUG /Fe"zxdbg.exe" zx.c cpmdrv.c cpmglob.c cpmparse.c cpmredir.c drdos.c util.c xlt.c zxbdos.c zxcbdos.c zxdbdos.c z80.c dirent.c



WARNING: There seems to be a rare scenario that breaks zx under the Open Watcom build.  CP/M allows a file to be accessed

under multiple FCB's without an error.  Open Watcom will see this as an error.  At present, the only tool I know of that does

this is M80.

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).



The GPL status of everything remains in place and carries forward.
