= Mandatory Prerequisites =
|
|
|
|
* GCC, MSVC (9, 10, 11, 12), Xcode or Intel C/C++
|
|
* CMake 2.8.8 or later http://www.cmake.org
|
|
* On linux, ccmake is helpful, usually a package named cmake-curses-gui
|
|
|
|
Note: MSVC12 requires cmake 2.8.11 or later
|
|
|
|
|
|
= Optional Prerequisites =
|
|
|
|
1. Yasm 1.2.0 or later, to compile assembly primitives (performance)
|
|
|
|
For Windows, download the latest yasm executable
|
|
http://yasm.tortall.net/Download.html and copy the EXE into
|
|
C:\Windows or somewhere else in your %PATH% that a 32-bit app (cmake)
|
|
can find it. If it is not in the path, you must manually tell cmake
|
|
where to find it. Note: you do not need the vsyasm packages, x265
|
|
does not use them. You only need the yasm executable itself.
|
|
|
|
On Linux, the packaged yasm may be older than 1.2, in which case
|
|
so you will need get the latest source and build it yourself.
|
|
|
|
Once YASM is properly installed, run cmake to regenerate projects. If you
|
|
do not see the below line in the cmake output, YASM is not in the PATH.
|
|
|
|
-- Found Yasm 1.3.0 to build assembly primitives
|
|
|
|
Now build the encoder and run x265 -V:
|
|
|
|
x265 [info]: using cpu capabilities: MMX, SSE2, ...
|
|
|
|
If cpu capabilities line says 'none!', then the encoder was built
|
|
without yasm.
|
|
|
|
2. VisualLeakDetector (Windows Only)
|
|
|
|
Download from https://vld.codeplex.com/releases and install. May need
|
|
to re-login in order for it to be in your %PATH%. Cmake will find it
|
|
and enable leak detection in debug builds without any additional work.
|
|
|
|
If VisualLeakDetector is not installed, cmake will complain a bit, but
|
|
it is completely harmless.
|
|
|
|
|
|
= Build Instructions Linux =
|
|
|
|
1. Use cmake to generate Makefiles: cmake ../source
|
|
2. Build x265: make
|
|
|
|
Or use our shell script which runs cmake then opens the curses GUI to
|
|
configure build options
|
|
|
|
1. cd build/linux ; ./make-Makefiles.bash
|
|
2. make
|
|
|
|
|
|
= Build Instructions Windows =
|
|
|
|
We recommend you use one of the make-solutions.bat files in the appropriate
|
|
build/ sub-folder for your preferred compiler. They will open the cmake-gui
|
|
to configure build options, click configure until no more red options remain,
|
|
then click generate and exit. There should now be an x265.sln file in the
|
|
same folder, open this in Visual Studio and build it.
|
|
|
|
= Version number considerations =
|
|
|
|
Note that cmake will update X265_VERSION each time cmake runs, if you are
|
|
building out of a Mercurial source repository. If you are building out of
|
|
a release source package, the version will not change. If Mercurial is not
|
|
found, the version will be "unknown".
