This repository contains a fork of 64tass, command-line assembler for the 65xx processor family.

This code is based off of the download on the project page on SourceForge: https://sourceforge.net/projects/tass64/

List of changes:

• This readme file was added
• After assembling, only print "Errors:" and "Warnings:" if nonzero errors or warnings. (Reason: otherwise Visual Studio gets confused)
• Add a debug build config to makefile
• Fix debug build

This is for building the Windows version, on Windows. This is one way of doing it. Other ways may work, as well.

1. Set up and launch Windows Subsystem for Linux (WSL). For distribution, choose Ubuntu 18.04 LTS.
2. Run the following commands

apt install make

apt-get update

sudo apt-get install build-essential

sudo apt-get install gcc-mingw-w64

make -f makefile.win

At the end, 64tass.exe will be placed in the source folder.

After making changes, use

make clean

make -f makefile.win

to re-compile.

Use

make -f makefile.win DEBUG=1

to build debug. If DEBUG=0 or not specified, then it is release config. Since this build uses the MinGW compiler, it does not produce PDBs, so GDB may be necessary for symbolic debugging
