Doesn't compile under Ubuntu 14.04 x86 (cmake 2.8.12)

[Anton]

Hello there. I downloaded from https://bitbucket.org/multicoreware/x265/downloads/ x265_2.5.tar.gz Then unpacked. Then

 ./make-Makefiles.bash

after that I got an error (to be honest, I'm almost always got an error when I trying to compile smth with CMake. I hate it) Logs are included.

If you don't have installed C++ compiler, you can try with

sudo apt install g++

[Anton]

It was not installed. Still, it wasn't in documentation. https://bitbucket.org/multicoreware/x265/wiki/Home only mentioned in Building "To compile x265 you must first install Mercurial (or TortoiseHg on Windows) and CMake 2.8.8 or later" interested thing, in https://bitbucket.org/multicoreware/x265/src/tip/build/README.txt?at=default&fileviewer=file-view-default Mentioned CMake 2.8.11 or later. Then I tried it again. Failed, logs are included as cmake output2.zip in first message

after installed g++

There is instruction for Ubuntu in documentation:

sudo apt-get install mercurial cmake cmake-curses-gui build-essential yasm

It is missing g++ (should be fixed, thanks for report). I've downloaded 32-bit Ubuntu 14.04 and it is possible (with installed g++ mercurial cmake cmake-curses-gui build-essential yasm) to build x265:

ma@ma-VirtualBox:~/m/x265_2.5/build/linux$ ./x265 -V
x265 [info]: HEVC encoder version 2.5
x265 [info]: build info [Linux][GCC 4.8.4][32 bit] 8bit
x265 [info]: using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX

[Anton]

Now, I have Installed cmake-curses-gui build-essential yasm. Still doesn't work. Something broken, now there no log files as output, though in the terminal they were mentioned. There are a following problem in the terminal mentioned:

Could NOT find NUMA (missing:  NUMA_ROOT_DIR NUMA_INCLUDE_DIR NUMA_LIBRARY)

[Ma0]

Confirmed, in my Ubuntu 14.04 it is the same warning message. You could just ignore it. After ./make-Makefiles.bash please in cmake-gui press key c (to configure) and next press key g (to generate and exit). Last command to execute is make.

[Anton]

For that command

cmake-gui

I first need to install cmake-qt-gui

(which was not mentioned anywhere as well)

Generated to new folder and only after that make command starts doing something. "100% Built target x265-static"

After documentation will be updated both on Home and on building help this issue could be closed. I'm very grateful to Ma0's help.

One last question, but it a bit an offtopic here. What I should to do with this elf file? I just want to play x265 in my VLC... It was my original intention, because vlc-plugin-libde265 doesn't help me. My VLC 2.1.6 before this cannot play video in this x265 videos (only sound), but after installing it crashes immediately.

Did all these packages, listed in our docs, install without errors: mercurial cmake cmake-curses-gui build-essential yasm? If so, build-essentials should give you g++, and cmake-curses-gui should give you cmake-gui. And the NUMA message just says that you don't have libnuma installed. If you're running on a single socket server, or a desktop/laptop, it is safe to ignore.

Regarding your question on VLC, x265 is a video "encoder". If you're looking to play HEVC video in VLC, you need to be looking for an HEVC "decoder".
