Downloading, building & installing

Downloading

Libgpiod is packaged by several linux distributions. You should typically be able to install it using your package manager. If you want to build libgpiod from sources, the upstream git repository for libgpiod is hosted at kernel.org. together with release tarballs.

Building

This is a pretty standard autotools project. The core C library does not have any external dependencies other than the standard C library with GNU extensions.

The build system requires the following packages to be installed on the host system for the basic build:

• autotools

• autoconf-archive

• libtool

• pkg-config

Note

Development files for additional libraries may be required depending on selected options. The configure script will report any missing additional required dependencies.

To build the project (including command-line utilities) run:

./autogen.sh --enable-tools=yes
make

Note

The command-line tools optionally depend on libedit for the interactive feature.

The autogen script will execute ./configure and pass all the command-line arguments to it.

Note

If building from release tarballs, the configure script is already provided and there’s no need to invoke autogen.sh.

For all configure features, see: ./configure --help.

Installing

To install the project run:

make install

Note

The above may require superuser privileges.

This will install libgpiod under the default system paths. If you want to install it under non-standard path, pass the --prefix=<install path> option to configure.
