OpenHarmony移植之编译工具链

1、下载工具链

选择得当本身芯片的arm编译工具链，因为我的是arm cortex-a9的芯片，以是我选择如下交叉工具链
Downloads | GNU-A Downloads – Arm DeveloperDownload the The GNU Toolchain for the Cortex-A Family are integrated and validated packages featuring the GCC compiler, libraries and other GNU tools necessary for software development on devices based on the Arm Cortex-A processors or the Arm A-profile architecture.
https://developer.arm.com/downloads/-/gnu-a

2、将工具链放入OpenHarmony目次

2.1、放入prebuilts目次下面


3、配置编译工具链

3.1、在device目次下配置编译工具链

  1. device/board/exynos/fs4412/linux/config.gni
  2. # Board CPU type, e.g. "cortex-a7", "riscv32".
  3. board_cpu = "cortex-a9"
  5. # Board arch, e.g.  "armv7-a", "rv32imac".
  6. board_arch = "armv7"
  8. # Toolchain name used for system compiling.
  9. # E.g. gcc-arm-none-eabi, arm-linux-harmonyeabi-gcc, ohos-clang,  riscv32-unknown-elf.
  10. # Note: The default toolchain is "ohos-clang". It's not mandatory if you use the default toolchain.
  11. board_toolchain = "arm-none-linux-gnueabi-gcc"
  13. # The toolchain path installed, it's not mandatory if you have added toolchain path to your ~/.bashrc.
  14. board_toolchain_path = "~/openharmony/openharmony_3.2/prebuilts/gcc-4.6.4/bin"
  16. # Compiler prefix.
  17. board_toolchain_prefix = "arm-none-linux-gnueabi-"
  19. # Compiler type, "gcc" or "clang".
  20. board_toolchain_type = "gcc"
复制代码
3.2、在kernel/linux/build目次下配置编译工具链

  1. kernel/linux/build/kernel.mk
  2. diff --git a/kernel.mk b/kernel.mk
  3. index dc3343b..415e4d0 100644
