Linking to system libcec
This crate works with libcec
v4.x, v5.x and v6.x (latest version as time of writing). During the build we try to find libcec
system library installation using pkg-config
and compilation using default C compiler (cc
crate). As a fallback, vendored libcec
(v6.x) is used during the build.
Alternatively, one can the decide to skip logic above and force the use of vendored sources by enabling vendored
feature.
The crate is tested mainly with Linux and Windows but could work with other platforms as well. PRs welcome.
Linux (general)
On Linux, for most convenient build process, it is recommended to install pkg-config
, libcec-dev
(headers and pkg-config configuration), libcec6
(dynamic library), libp8-platform-dev
and libp8-platform2
from your package distribution before installing this crate. Exact package names vary between distributions and package managers.
In addition libudev-dev
might be needed.
With debian based distributions, you can simply
sudo apt-get install libudev-dev libp8-platform2 libp8-platform-dev libcec-dev pkg-config libcec6
Raspberry Pi OS
If you are using Raspberry Pi OS and want to use the built-in HDMI port CEC, you might need to build the libcec yourself, since the libcec as packaged by debian is not providing the driver (as of 2022)
Adapted from libcec documentation:
# Become superuser
sudo su
# Remove libcec (since we are going to build it ourselves)
apt-get remove libcec6
# Install libcec build dependencies, but not libcec itself
apt-get install libp8-platform-dev libp8-platform2 cmake libudev-dev libxrandr-dev python3-dev swig git
# Build libcec 6.0.2 with RPI CEC driver enabled
rm -rf /tmp/libcec-build-tmp
mkdir /tmp/libcec-build-tmp
cd /tmp/libcec-build-tmp
git clone --recursive https://github.com/Pulse-Eight/libcec.git
cd libcec
git checkout libcec-6.0.2
mkdir build
cd build
cmake -DRPI_INCLUDE_DIR=/opt/vc/include -DRPI_LIB_DIR=/opt/vc/lib ..
make -j4
make install
ldconfig
# Leave superuser context
exit
Windows
On Windows, it is recommended to install libcec
via the installer and add cec.dll
to the PATH
environment variable.
For a vendored build, libcec-sys
will dynamically link to the compiled cec.dll
. This means you must package your standalone executable with the compiled dynamic library.
Vendored Build Prerequisites:
- Visual Studio 2019 w/
Desktop Development with C++
andUniversal Windows Platform development
- CMake 3.12+
- Python 3.6+ with Debug Binaries
