1 = Mandatory Prerequisites =
|
|
|
2
|
|
|
3 * GCC, MSVC (9, 10, 11, 12), Xcode or Intel C/C++
|
|
|
4 * CMake 2.8.8 or later http://www.cmake.org
|
|
|
5 * On linux, ccmake is helpful, usually a package named cmake-curses-gui
|
|
|
6
|
|
|
7 Note: MSVC12 requires cmake 2.8.11 or later
|
|
|

|
|
|
10 = Optional Prerequisites =
|
|
|
11
|
|
|
12 1. Yasm 1.2.0 or later, to compile assembly primitives (performance)
|
|
|
13
|
|
|
14 For Windows, download the latest yasm executable
|
|
|
15 http://yasm.tortall.net/Download.html and copy the EXE into
|
|
|
16 C:\Windows or somewhere else in your %PATH% that a 32-bit app (cmake)
|
|
|
17 can find it. If it is not in the path, you must manually tell cmake
|
|
|
18 where to find it. Note: you do not need the vsyasm packages, x265
|
|
|
19 does not use them. You only need the yasm executable itself.
|
|
|
20
|
|
|
21 On Linux, the packaged yasm may be older than 1.2, in which case
|
|
|
22 so you will need get the latest source and build it yourself.
|
|
|
23
|
|
|
24 Once YASM is properly installed, run cmake to regenerate projects. If you
|
|
|
25 do not see the below line in the cmake output, YASM is not in the PATH.
|
|
|
26
|
|
|
27 -- Found Yasm 1.3.0 to build assembly primitives
|
|
|
28
|
|
|
29 Now build the encoder and run x265 -V:
|
|
|
30
|
|
|
31 x265 [info]: using cpu capabilities: MMX, SSE2, ...
|
|
|
32
|
|
|
33 If cpu capabilities line says 'none!', then the encoder was built
|
|
|
34 without yasm.
|
|
|
35
|
|
|
36 2. VisualLeakDetector (Windows Only)
|
|
|
37
|
|
|
38 Download from https://vld.codeplex.com/releases and install. May need
|
|
|
39 to re-login in order for it to be in your %PATH%. Cmake will find it
|
|
|
40 and enable leak detection in debug builds without any additional work.
|
|
|
41
|
|
|
42 If VisualLeakDetector is not installed, cmake will complain a bit, but
|
|
|
43 it is completely harmless.
|
|
|

|
|
|
45
|
|
|
46 = Build Instructions Linux =
|
|
|
47
|
|
|
48 1. Use cmake to generate Makefiles: cmake ../source
|
|
|
49 2. Build x265: make
|
|
|
50
|
|
|
51 Or use our shell script which runs cmake then opens the curses GUI to
|
|
|
52 configure build options
|
|
|
53
|
|
|
54 1. cd build/linux ; ./make-Makefiles.bash
|
|
|
55 2. make
|
|
|
56
|
|
|
57
|
|
|
58 = Build Instructions Windows =
|
|
|
59
|
|
|
60 We recommend you use one of the make-solutions.bat files in the appropriate
|
|
|
61 build/ sub-folder for your preferred compiler. They will open the cmake-gui
|
|
|
62 to configure build options, click configure until no more red options remain,
|
|
|
63 then click generate and exit. There should now be an x265.sln file in the
|
|
|
64 same folder, open this in Visual Studio and build it.
|
|
|
65
|
|
|
66 = Version number considerations =
|
|
|
67
|
|
|
68 Note that cmake will update X265_VERSION each time cmake runs, if you are
|
|
|
69 building out of a Mercurial source repository. If you are building out of
|
|
|
70 a release source package, the version will not change. If Mercurial is not
|
|
|
71 found, the version will be "unknown".
