Building

To build from source, first ensure the following dependencies are installed:

GCC 4.8+ or Clang
GNU Make 4.0+
iconv library (usually provided by libc on Linux/FreeBSD)

...then download and unpack the latest release tarball:

curl -LO https://craigbarnes.gitlab.io/dist/dte/dte-1.11.1.tar.gz
tar -xzf dte-1.11.1.tar.gz
cd dte-1.11.1

...and compile and install:

make && sudo make install

If you're using macOS, it may be necessary to install a more recent version of GNU Make (e.g. with brew) and then use gmake in place of make. For example:

brew install make
gmake && sudo gmake install

Documentation

After installing, you can access the documentation in man page format:

The primary git repository and issue tracker is hosted at https://gitlab.com/craigbarnes/dte.

The project is also on various other code hosting sites, but these are only secondary mirrors and may occasionally lag behind GitLab by a few hours.
