Introduction to Dtc
The dtc package contains the
Device Tree Compiler for working with device tree source and binary
files and also libfdt, a utility library for reading and
manipulating device trees in the binary format.

Note
Development versions of BLFS may not build or run some packages
properly if LFS or dependencies have been updated since the most
recent stable versions of the books.
Package Information
Dtc Dependencies
Optional
libyaml-0.2.5, SWIG-4.3.0, and texlive-20240312
Installation of Dtc
Install dtc by running the
following commands:
mkdir build &&
cd build &&
meson setup --prefix=/usr \
--buildtype=release \
-D python=disabled .. &&
ninja
To test the results, issue: meson
test -v.
Now, as the root user:
ninja install
Still as the root user, remove the
useless static library:
rm /usr/lib/libfdt.a
If you have texlive-20240312 installed, you can
build the PDF format of the documentation by issuing the following
command:
pushd ../Documentation
latexmk -bibtex --pdf dtc-paper &&
latexmk -bibtex --pdf dtc-paper -c
popd
To install the documentation, as the root user issue the following command:
cp -R ../Documentation -T /usr/share/doc/dtc-1.7.1
If you have installed SWIG-4.3.0 and you wish to install the Python 3
bindings of this package, build the Python 3 module:
pip3 wheel -w dist --no-build-isolation --no-deps --no-cache-dir ..
As the root user, install the
Python 3 module:
pip3 install --no-index --find-links=dist --no-cache-dir --no-user libfdt
Command Explanations
--buildtype=release:
Specify a buildtype suitable for stable releases of the package, as
the default may produce unoptimized binaries.
-D python=disabled: This
switch prevents building the Python 3 binding with the deprecated
method (running setup.py directly). We will build
the Python 3 binding with the pip3
wheel command separately if wanted.
