yasm-1.3.0 (or NASM-2.16.01, pass
the -DENABLE_NASM=yes
option to
cmake if you want to
use it instead of yasm)
Install libaom by running the following commands:
mkdir aom-build && cd aom-build && cmake -DCMAKE_INSTALL_PREFIX=/usr \ -DCMAKE_BUILD_TYPE=Release \ -DBUILD_SHARED_LIBS=1 \ -DENABLE_DOCS=no \ -G Ninja .. && ninja
To test the results, issue: ninja runtests. Note that the tests take an extremely long time to run.
Now, as the root
user:
ninja install && rm -v /usr/lib/libaom.a
-DBUILD_SHARED_LIBS=1
: This
switch builds shared versions of the libraries.
-DENABLE_DOCS=no
: This
switch disables building the documentation because it fails due to
an incompatibility with the latest version of Doxygen-1.9.7.
-DENABLE_NASM=yes
: Use this switch if
you have NASM-2.16.01 installed and wish to use it
instead of yasm.
