CLion中通过ST-Link v3调试STM32WB55时CMake配置报错求助

我在CLion中尝试通过ST-Link v3调试搭载STM32WB55的自定义PCB，配置时遇到如下CMake错误：

CMake Error at CMakeLists.txt:18 (project):
  The CMAKE_ASM_COMPILER:

    /opt/homebrew/Cellar/arm-none-eabi-gcc/bin/arm-none-eabi-gcc

  is not a full path to an existing compiler tool.

  Tell CMake where to find the compiler by setting either the environment
  variable "ASM" or the CMake cache entry CMAKE_ASM_COMPILER to the full path
  to the compiler, or to the compiler name if it is in the PATH.

我已确认路径正确，且重装过arm-none-eabi-gcc，但问题仍未解决。以下是我的CMake配置文件：

解决方案 #

• 清除CMake缓存并重新配置：CMake报错中显示的汇编编译器路径与配置的不一致，说明存在旧缓存。删除项目下的cmake-build-*文件夹，重启CLion后重新加载CMake配置。
• 验证编译器可执行性：在终端执行以下命令，确认编译器路径有效且可执行：

  /opt/homebrew/bin/arm-none-eabi-gcc --version
  

  若提示权限问题，执行sudo chmod +x /opt/homebrew/bin/arm-none-eabi-gcc赋予可执行权限。
• 调整CMake配置顺序：将cmake_minimum_required(VERSION 3.26)移到配置最顶部，CMake要求版本声明优先于系统和编译器配置，否则可能导致变量未被正确识别。修改后的开头如下：

  cmake_minimum_required(VERSION 3.26)
  set(CMAKE_SYSTEM_NAME Generic)
  set(CMAKE_SYSTEM_VERSION 1)
  
  # specify cross-compilers and tools
  set(CMAKE_C_COMPILER /opt/homebrew/bin/arm-none-eabi-gcc)
  set(CMAKE_CXX_COMPILER /opt/homebrew/bin/arm-none-eabi-g++)
  set(CMAKE_ASM_COMPILER /opt/homebrew/bin/arm-none-eabi-gcc)
  

• 通过环境变量指定汇编器：在CLion的「Settings → Build, Execution, Deployment → CMake」中，添加环境变量ASM=/opt/homebrew/bin/arm-none-eabi-gcc；或在终端启动CLion前设置环境变量：

  export ASM=/opt/homebrew/bin/arm-none-eabi-gcc
  open -a CLion
  

• 修复Homebrew链接：Homebrew安装的工具可能存在链接失效，执行以下命令重新安装并链接：

  brew reinstall arm-none-eabi-gcc
  brew link --overwrite arm-none-eabi-gcc
