LINUX 高通平台交叉编译tangram-es

• 下载源码，参选：

https://blog.csdn.net/quantum7/article/details

• 安装LINUX用编译工具

cmake, ninja

• 交叉编译工具

假设放在/usr/local/x86

• 编写aarch64-oe.cmake

  set(CMAKE_SYSTEM_NAME Linux)
  set(CMAKE_SYSTEM_PROCESSOR aarch64)

  高通OE交叉编译器前缀

  set(TOOLCHAIN_PREFIX "aarch64-oe-linux-")
  set(CMAKE_C_COMPILER {TOOLCHAIN_PREFIX}gcc) set(CMAKE_CXX_COMPILER {TOOLCHAIN_PREFIX}g++)
  set(CMAKE_AR {TOOLCHAIN_PREFIX}ar) set(CMAKE_RANLIB {TOOLCHAIN_PREFIX}ranlib)
  set(CMAKE_LIBRARY_ARCHIVER ${TOOLCHAIN_PREFIX}ar)

  Sysroot路径

  set(TOOLCHAIN_SYSROOT "/usr/local/x86-aarch64-toolchain/sysroots/aarch64-oe-linux")
  set(CMAKE_SYSROOT ${TOOLCHAIN_SYSROOT})

  交叉查找规则

  set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
  set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
  set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
  set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY)

  编译flag适配高通AArch64

  set(CMAKE_C_FLAGS "-march=armv8-a -O2 -Os")
  set(CMAKE_CXX_FLAGS "-march=armv8-a -O2 -Os -include limits")

• 编译脚本

  #!/bin/bash
  set -e

  SOURCE_ROOT_PATH=pwd

  TOOLCHAIN_PATH=/usr/local/x86-aarch64-toolchain
  CROSS_NAME=aarch64-oe-linux
  CROSS_BIN={TOOLCHAIN_PATH}/sysroots/x86_64-qtisdk-linux/usr/bin/{CROSS_NAME}
  export PATH={CROSS_BIN}:{PATH}

  . {TOOLCHAIN_PATH}/environment-setup-aarch64-oe-linux . {TOOLCHAIN_PATH}/environment-setup-aarch64-oe-linux-sdllvm

  配置全局变量

  TOOLCHAIN_FILE="{SOURCE_ROOT_PATH}/aarch64-oe.cmake" SYSROOT="{TOOLCHAIN_PATH}/sysroots/aarch64-oe-linux"

  PLATFORM_NAME=arm64
  INSTALL_DIR="HOME/tangram_{PLATFORM_NAME}install"
  BUILD_DIR="build${PLATFORM_NAME}"

  make clean
  rm -rf CMakeCache.txt CMakeFiles
  rm -rf ${INSTALL_DIR}

  清理构建目录

  rm -rf BUILD_DIR mkdir -p BUILD_DIR
  cd $BUILD_DIR

  CMake 完整参数

  cmake ..
  -G Ninja
  -DCMAKE_TOOLCHAIN_FILE={TOOLCHAIN_FILE} \ -DCMAKE_INSTALL_PREFIX={INSTALL_DIR}
  -DCMAKE_FIND_ROOT_PATH=${SYSROOT}
  -DCMAKE_FIND_ROOT_PATH_MODE_PACKAGE=ONLY
  -DCMAKE_BUILD_TYPE=Release
  -DRENDER_BACKEND=NONE
  -DTANGRAM_PLATFORM=NONE
  -DTANGRAM_ENABLE_3D=OFF
  -DTANGRAM_USE_EGL=OFF
  -DTANGRAM_USE_SDL=OFF
  -DTANGRAM_USE_QT=OFF
  -DTANGRAM_USE_GLFW=OFF
  -DTANGRAM_USE_METAL=OFF
  -DTANGRAM_MBTILES=ON
  -DBUILD_SHARED_LIBS=ON

  编译&安装

  ninja -j$(nproc)
  ninja install

• 检查结果

  echo "编译完成，输出目录：{INSTALL_DIR}" ls -l {INSTALL_DIR}/lib

  file {SOURCE_ROOT_PATH}/{BUILD_DIR}/core/libtangram-core.so
