An assembler is a program that translates assembly language source code into machine code. A commonly used assembler that produces machine code for 6502 CPUs is CA65, which is distributed as part of the CC65 package. These instructions tell how to install and run CA65 on Windows 2000 or Windows XP.
Windows is shipped with file name extensions hidden in Windows Explorer. This misfeature was originally intended to make Windows 95 look more like Mac OS 7.5, which did not use file name extensions. But hiding makes it easier to accidentally create a file name with two extensions. Worse yet, destructive software such as the ILOVEYOU worm (Wikipedia article) has shipped with two extensions: one to indicate to the operating system that the file is executable and one to fool the user into thinking that the file is not executable (and thus safe). The first thing we will do is turn on the display of file name extensions in Windows Explorer:
Windows 2000 does not come with software to extract files from PKZIP archives.
Windows XP comes with a bare-bones archiver called Compressed Folders that can only handle PKZIP archives (.zip
), not rar or 7z or tar or gz or bz2 files.
The 7-Zip package can extract files from all of them, as well as add files to PKZIP and 7-Zip archives.
cc65-win32-#####.zip
and cc65-doc-#####.zip
packages to your computer. (The ##### represents a version number, such as 2.11.0-1, which may change before you read this.) The cc65-win32
contains the CC65 package compiled for Windows, and cc65-doc
contains the manual.cc65-win32-#####.zip
to a new folder.install.vbs
file as an administrator to copy it to Program Files.Log out and log in to complete installation.
Absolute easiest method:
Set up you repository there as it says on the homepage. Using software sources and import the gpg key. or add this to your software sources list:
deb http://debian.trikaliotis.net/ stable contrib
Download: KeyFile add to authentication sources.
Then:
sudo apt-get install cc65
On Debian or Ubuntu, open a terminal and enter the following commands.
On Fedora, CentOS, and their descendants, the apt
command will need to be changed.
sudo apt install build-essential git mkdir -p ~/develop cd ~/develop git clone https://github.com/cc65/cc65.git cd cc65 nice make -j2 make install PREFIX=~/.local which cc65
If your account has been configured to run applications built from source and installed for one user, the last step should show /home/<username>/.local/bin/cc65
.
If it does not, add ~/.local/bin
to your PATH
environment variable:
nano ~/.bashrc # and add the following at the end of the file if [ -d "$HOME/.local/bin" ] ; then PATH="$HOME/.local/bin:$PATH" fi
Press Ctrl+O Enter to save, then Ctrl+X to quit, and the change to PATH
will take effect the next time you log in.
Using Homebrew: On computer with Homebrew installed, open Terminal and type "brew install cc65". Everything else should be automatic.
