To build the DLA suite, you need a Unix/GNU like system (which might even be modern Windows), with the following software installed: - Required: A "make" command. This can be GNU or BSD make. The Makefile doesn't use any special features, so pretty much any version should be OK. - Required: "cl65", from CC65, the cross-compiler for the 6502. Any recent version should do; I used 2.19. - Optional: "perl", the Perl 5 interpreter. Only used to generate the files dlatbl.s, dlaver.inc, dlaver.h, and (for "make disk"), about.dat. These files are part of the source distribution, so you only need Perl if you're going to modify the data tables (the mkdlatbl.pl script), or change the version number (mkver.pl), or the intro screen in dla.atr (ABOUT.txt). - Optional: "cc", a host C compiler (e.g. gcc or clang). Only used for compiling dla2csv for the host. - Optional: "axe", only needed for "make disk". Get it here: https://slackware.uk/~urchlay/repos/bw-atari8-tools/ You should be able to build everything from a terminal by typing "make" in the source directory. This will build dla.xex, dla2csv.xex, and (if possible) dla2csv for the host. If you want a disk image, you can try "make disk", which will create dla.atr (if you have axe on your $PATH). The disk is MyDOS formatted, single density. Ideally, all the software should be found in your $PATH. If not, you can set the full paths by defining them on the make command line. Example that sets all 3: make CL65=/opt/cc65/bin/cl65 PERL=/usr/local/perl/bin/perl5 CC=/usr/bin/clang Also you could set CFLAGS and CL65FLAGS, if you can think of a reason to do that. If you have trouble building on Linux, ask me for help. I can be found on irc.libera.chat in the ##atari channel, as user name Urchlay. If you have trouble on other OSes, ask someone who actually knows about your OS (not me, I don't do Windows or Mac). Other make targets: make test - runs dla.xex in atari800 make disktest - runs dla.atr in atari800 make realtest - serves dla.atr as drive 1, via atariserver (for testing on real hardware) make clean - does what you expect make distclean - also removes generated files
