Dependencies and build environment
To build µEMACS, you need to have gcc, gmake and ncurses development library installed.
Checking environment
gcc and gmake are often preinstalled with gmake set as the default make. Use your favorite package manager to check their availability.
% which gcc make /usr/bin/gcc /usr/bin/make % apt list gcc make gcc/focal,now 4:9.3.0-1ubuntu2 amd64 [installed] make/focal,now 4.2.1-1.2 amd64 [installed]
Use your favorite package manager if they need to be installed.
% sudo apt install gcc make
To check that make is actually GNU make:
% make --version GNU Make 4.2.1 Built for x86_64-pc-linux-gnu Copyright (C) 1988-2016 Free Software Foundation, Inc. License GPLv3+: GNU GPL version 3 or later http://gnu.org/licenses/gpl.html This is free software: you are free to change and redistribute it. There is NO WARRANTY, to the extent permitted by law.
ncurses development library usually need to be installed. Query your favorite package manager to check which packages are available for installation:
% apt search libncurses
Use your favorite package manager to install the needed package:
% sudo apt install libncurses-dev
On Ubuntu, apt will select the package that matches your architecture (amd64 or i386).
Getting the sources
µEMACS source code is available on github and mirrored at git.sdf.org. You can either clone the git repository or download a zip archive.
Move to working directory and clone: % mkdir ~/Projects % cd ~/Projects % git clone https://github.com/rfivet/uemacs.git
Building
% cd ~/Projects/uemacs % make depend % make
If gmake is not set as the default make you will have to call it explicitly
% gmake depend % gmake
Testing
Start the editor: % ./ue To leave the editor type CTL-X CTL-C Execute a sample script: % ./ue -x screensize.cmd
