DASM 2.20.12 README
Welcome to DASM, a versatile macro assembler with support for several
8-bit microprocessors including MOS 6502 & 6507; Motorola 6803, 68705,
and 68HC11; Hitachi HD6303 (extended Motorola 6801); and Fairchild F8.
This file describes the DASM distribution, how to compile and install
DASM, and where to get more information about DASM.
DASM's homepage is http://dasm-dillon.sourceforge.net/ since release
The DASM distribution contains the following important files and
directories of interest to all users:
bin/ Executables for DASM and related tools
(only if you downloaded a binary distribution)
doc/ Documentation and manuals
machines/ Support files for various 8-bit machines
AUTHORS List of contributors to DASM
COPYING GNU General Public License
CREDITS People who helped with DASM in some way
FUTURE Plans for the next releases of DASM
NEWS Recent changes to DASM
README The file you are reading right now :-)
In addition, developers are going to be interested in the following
files and directories:
src/ Source code for DASM and related tools
test/ Test cases for DASM and related tools
(as of release 2.20.12 the test framework is incomplete)
ChangeLog Source level changes to DASM
Makefile Makefile to build DASM executables, run tests, and
Even more files for developers are available from the DASM Subversion
repository, see http://dasm-dillon.sf.net/ for details.
Compiling and Installing
If you are using DASM on a Unix system, you should be able to simply
give the command
in the root directory of the DASM distribution and DASM should build.
A bin/ directory containing DASM executables will be created as part
of this process. You can also give the command
to run all the test cases that come with the distribution. Note that
as of release 2.20.12 the test framework is incomplete and probably
only remotely comprehensible for developers. :-/ The often-used
does not work as of release 2.20.12 either, mostly because DASM does
not yet use GNU autotools. You have to install DASM by hand, either
by adding the bin/ directory to your path, or by copying executables
to another directory in your path. For include files in the machines/
directory you currently have to use DASM's -I command line option.
NOTE: Several compiler warnings will be displayed during the build
process. We are confident that you can ignore these warnings.
They will be dealt with in a future release. (And if you know
how to fix them reliably, we welcome your contributions!)
DASM has been built and tested successfully on the following machines
and operating systems:
- SunOS 5.10 Generic_118822-11 sun4u sparc
- Linux 22.214.171.124-80.fc7 i386 GNU/Linux
- Darwin 8.11.0 powerpc
- NetBSD 3.0 qube mips
- Linux 2.6.24-1-686 i686 GNU/Linux
- Linux-based cross-compile for Windows/Wine
- Windows using MinGW (see http://www.mingw.org/ for details)
If you have successfully built and tested DASM on a different machine
or operating system, we would love to hear about it.
The simplest way to get a brief introduction to DASM is to run the
bin/dasm executable without options, which will print a short help
message summarizing all available options.
The DASM distribution includes documentation in the doc/ directory.
However, the documentation is incomplete as of release 2.20.12. We
are urgently looking for volunteers to bring it up to date.
Documentation for using DASM to produce code for the F8 processor
is currently in the directory machines/channel-f/ but will be
integrated into the main documentation in the future.
The sourceforge.net project page provides access to two mailing
lists, one for announcements from the developers and one for DASM
users to discuss problems, help each other, and communicate with
the developers. See http://sourceforge.net/projects/dasm-dillon/
There is also a vibrant community of developers writing games and
demos for the Atari 2600 VCS using DASM. The mailing lists for the
Stella emulator are a particularly useful resource for DASM users,
not only those intent on programming for the VCS.
