calcurse is available on a number of Linux distributions:

Install the following build dependencies. If your distribution segments development files from core packages (i.e., *-devel or *-dev packages), you may need to install those as well:

• gcc
• autoconf-archive
• automake
• autopoint
• asciidoc (only needed for building documentation, can be skipped with --disable-docs)
• gettext with development files
• ncurses with development files

If you are using a release tarball, the following commands can be used to build and install calcurse:

$ ./configure
$ make
$ make install

Note that make install needs to be run as root. When working on a Git checkout, you need to run ./autogen.sh before ./configure.

• build-aux: auxiliary files for the build process
• contrib: useful tools such as hooks or the CalDAV synchronization script
• doc: detailed documentation in plain text and HTML
• po: translations and i18n-related files
• scripts: additional official scripts, such as calcurse-upgrade
• src: the actual calcurse source files
• test: test suite and test cases for calcurse

calcurse was created by Frederic Culot in 2004. Since 2011, the project is maintained by Lukas Fleischer. Many core features added to calcurse since 2017 were designed and implemented by Lars Henriksen.

Of course, there are numerous other contributors. Check the Git commit log and the Thanks section in the manual for a list of people who have contributed by reporting bugs, sending fixes, or suggesting improvements.
