Installation of x265

Install x265 by running the following commands: 

mkdir bld &&
cd    bld &&

cmake -DCMAKE_INSTALL_PREFIX=/usr \
      -DGIT_ARCHETYPE=1           \
      -Wno-dev ../source          &&
make

This package does not come with a test suite.

Now, as the root user: 

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

Command Explanations

-DGIT_ARCHETYPE=1: Upstream no longer provides releases. BLFS is using a git snapshot, but if the builder has not installed git the build will not install the shared library or the pkgconfig file without this switch.

-Wno-dev: This switch is used to suppress warnings intended for the package's developers.

rm -vf /usr/lib/libx265.a: BLFS does not recommend using static libraries.
