Classic Colors is a simple and efficient paint program for Unix systems, inspired by MS Paint (Windows 95-98 version). It is built on the time-tested Motif UI library, so it should last for a long time and be widely compatible with various Unix flavours.
For now, you must build from source (help making it available in package managers would be greatly appreciated.)
It has been tested on Debian (Ubuntu), OpenBSD, and macOS(Homebrew).
List
- gnumake
- X11 (XQuartz on mac)
- Motif (dev version)
- Xt
- Xpm
- Xp (only if motif on your platform is built with print support)
- pkg-config (usually comes with package manager)
Debian/Ubuntu:
sudo apt install libmotif-dev libxpm-dev libxext-dev
macOS (homebrew):
Install XQuartz either from the link, or homebrew cask:
brew install xquartz
If you just installed XQuartz for the first time make sure you restart otherwise you will get an error:
Error: Can't open display.
Now install motif:
brew install openmotif libxpm
NetBSD (pkgsrc)
pkgin install motif gmake pkg-config
OpenBSD
pkg_add motif gmake
openIndiana/Tribblix:
Classic colors is available as a package for Tribblix:
zap install-overlay classic-colors
Now you are ready to build:
./configure
make
make install
And run:
classic-colors
If you do not want to install in your path, the build output ./bin/classic-colors
is a standalone executable which can be moved around.
Classic colors uses the MIT SHM extension when available. This extension allows the display to refresh much faster. There is a fallback codepath when it is not available. It works well, it's just not as smooth.
SHM can be disabled at configuration time:
./configure --no-shm
Unfortunatly, macOS does not allow very much SYSV shared memory to be used,
and so it is likely if you resize the window very large it will exceed this limit and switch to the fallback codepath.
For the best experience on macOS you will need to increase this limit.
Create a file /etc/sysctl.conf containing the following:
kern.sysv.shmmax=134217728
kern.sysv.shmmin=1
kern.sysv.shmmni=1024
kern.sysv.shmseg=256
kern.sysv.shmall=32768
Restart the system after making this change.
If motif is not available in a package you will need to build it manually.
