Clion（stm32嵌入式开发）CMake未找到arm-none-eabi-gcc编译器

Question

我制作了类似教程https://blog.jetbrains.com/clion/2019/02/clion-2019-1-eap-clion-for-embedded-development-part-iii/?gclid=CjwKCAjwhOD0BRAQEiwAK7JHmKUzvoJnORtCn3YxpsSb00Ep_dE0gNQOytiXVgFj6EXOjyCAIH9XTBoCngQQAvD_BwE&gclsrc=aw.ds的项目

[我从https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads获得手臂工具链

通过.bashrc将bin文件夹添加到PATH。控制台命令运行良好：

$ arm-none-eabi-gcc
arm-none-eabi-gcc: fatal error: no input files

在Clion中使用STM32CubeMX cmake创建项目后未配置：

-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
-- The ASM compiler identification is unknown
-- Found assembler: arm-none-eabi-gcc
CMake Error at CMakeLists.txt:34 (PROJECT):
  The CMAKE_C_COMPILER:

    arm-none-eabi-gcc

  is not a full path and was not found in the PATH.

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

但是bin文件夹已经在PATH中了！！

如果通过pacman安装toolchail或将bin文件夹的所有内容复制到/ usr / bin /，但未找到其他文件，例如nano.specs，nosys.specs，stdint.h和其他包含文件，则可以查看编译器。

我不知道Clion和CubeMX如何指向正确的工具链。

似乎您的cmake找不到C / C ++编译器。在CLion工具链设置中，您可以指定编译器的路径（在您的情况下为arm-none-eabi-gcc和arm-none-eabi-g ++），或仅通过CMAKE_C_COMPILER和CMAKE_CXX_COMPILER定义将其传递给CMkae。
