Installation of x265

First, change the CMake policy to allow building with CMake-4.0 and newer: 

sed -r '/cmake_policy.*(0025|0054)/d' \
  -i source/CMakeLists.txt

Install x265 by running the following commands: 

mkdir bld &&
cd    bld &&

cmake -D CMAKE_INSTALL_PREFIX=/usr        \
      -D GIT_ARCHETYPE=1                  \
      -D CMAKE_POLICY_VERSION_MINIMUM=3.5 \
      -W no-dev ../source &&

make

This package does not come with a test suite.

To install the package, first remove any old library versions. After installation, remove a static library. As the root user: 

make install &&
rm -vf /usr/lib/libx265.a

lib32-Installation of x265

Install lib32-x265 by running the following commands: 

rm -rf * &&
CC="gcc -m32" CXX="g++ -m32"              \
PKG_CONFIG_PATH=/usr/lib32/pkgconfig      \
cmake -D CMAKE_INSTALL_PREFIX=/usr        \
      -D LIB_INSTALL_DIR=lib32            \
      -D GIT_ARCHETYPE=1                  \
      -D CMAKE_POLICY_VERSION_MINIMUM=3.5 \
      -W no-dev ../source &&

make

This package does not come with a test suite.

To install the package, first remove any old library versions. After installation, remove a static library. As the root user: 

make DESTDIR=$PWD/DESTDIR install     &&
cp -vR DESTDIR/usr/lib32/* /usr/lib32 &&
rm -vf /usr/lib32/libx265.a           &&
rm -rf DESTDIR                        &&
ldconfig

Command Explanations

[Note]

Note

Inspect CMakeLists.txt and other CMake related files for a full list of options.

-D GIT_ARCHETYPE=1: This switch is needed because the build system will not generate a pkg-config file or install a shared library unless git-2.49.0 is installed. Git isn't required for anything else in this package, so this switch is used to work around it for users who do not want to install Git as a build dependency.

-D CMAKE_POLICY_VERSION_MINIMUM=3.5: This switch allows building this package with cmake-4.0 or newer.

-W no-dev: This switch is used to suppress warnings intended for the package developers.

rm -vf /usr/lib{,32}/libx265.a: This removes an unnecessary static library.
