    ubuntu下交叉编译x265

    二、交叉编译x265

    1. 下载源码

    下载x265：https://www.videolan.org/developers/x265.html

    Index of /pub/videolan/x265/：http://ftp.videolan.org/pub/videolan/x265/

    wget http://ftp.videolan.org/pub/videolan/x265/x265_2.7.tar.gz
 
tar -xvzf x265_2.7.tar.gz
cd /home/yoyo/360Downloads/x265_2.7/build/arm-linux

    2. 安装依赖

    sudo apt-get install yasm

    3. 修改 crosscompile.cmake

    x265_2.7/build/arm-linux/crosscompile.cmake。

    # CMake toolchain file for cross compiling x265 for ARM arch
# This feature is only supported as experimental. Use with caution.
# Please report bugs on bitbucket
# Run cmake with: cmake -DCMAKE_TOOLCHAIN_FILE=crosscompile.cmake -G "Unix Makefiles" ../../source && ccmake ../../source
 
set(CROSS_COMPILE_ARM 1)
set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_SYSTEM_PROCESSOR armv7l)
 
# specify the cross compiler
set(CMAKE_C_COMPILER /home/yoyo/360Downloads/toolchains/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc)
set(CMAKE_CXX_COMPILER /home/yoyo/360Downloads/toolchains/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++)
 
# specify the target environment
SET(CMAKE_FIND_ROOT_PATH /home/yoyo/360Downloads/toolchains/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc)

    4. 修改 make-Makefiles.bash

    #!/bin/bash
# Run this from within a bash shell
 
cmake -DCMAKE_INSTALL_PREFIX=/home/yoyo/360Downloads/x265_2.7/x265build/ -DCMAKE_TOOLCHAIN_FILE=crosscompile.cmake -G "Unix Makefiles" ../../source && ccmake ../../source

    5. 编译安装

    cd /home/yoyo/360Downloads/x265_2.7/build/arm-linux

# 修改权限
chmod +x make-Makefiles.bash

# 执行
./make-Makefiles.bash

# 编译
make -j8

# 安装
make install

    执行 make-Makefiles.bash，会弹出一个目录 ，我的配置如下：

     BIN_INSTALL_DIR                  bin

    6. 移植到开发板

    将编译好的文件，拷贝到开发板。

    # 拷贝 include
cp -r ./x265build/include/* /PATH/TO/arm-linux-gnueabihf/arm-linux-gnueabihf/libc/usr/include

# 拷贝lib
cp -r ./x265build/lib/* /PATH/TO/arm-linux-gnueabihf/arm-linux-gnueabihf/libc/usr/lib

    三、FAQ

    Q：arm-linux-gnueabihf/libc/usr/include/gnu/stubs.h:7:11: fatal error: gnu/stubs-soft.h: No such file or directory

    ARM 编译选项的默认关系 001

    Linux 编译应用程序报错：fatal error: gnu/stubs-soft.h: No such file or directory

    记录交叉编译时一个错误:fatal error: gnu/stubs-soft.h： No such file or directory

    错误原因：交叉编译工具链版本与目标平台(arm cpu)不兼容。

    解决方法：根据arm cpu的版本，修改 x265_2.7/source/CMakeLists.txt。

    # System architecture detection
string(TOLOWER "${CMAKE_SYSTEM_PROCESSOR}" SYSPROC)  # 获取arm型号
set(X86_ALIASES x86 i386 i686 x86_64 amd64)
set(ARM_ALIASES armv6l armv7l)  # 设置支持的arm型号
list(FIND X86_ALIASES "${SYSPROC}" X86MATCH)
list(FIND ARM_ALIASES "${SYSPROC}" ARMMATCH)  # 是否匹配型号
...
if(ARM AND CROSS_COMPILE_ARM)
    # set(ARM_ARGS -march=armv6 -mfloat-abi=soft -mfpu=vfp -marm -fPIC)
    set(ARM_ARGS -march=armv6 -mfloat-abi=hard -mfpu=neon-vfpv4 -marm -fPIC) # 修改

    查看arm cpu信息：

    cat /proc/cpuinfo
processor       : 0
model name      : ARMv7 Processor rev 4 (v7l)
BogoMIPS        : 14.40
