我想在我的 stm32 项目中使用 mbedtls，但在构建时遇到一些问题。 我必须使用arm-none-gcc编译器构建mbedtls，对吧？ 我的命令是:(在构建目录中)。

编译测试程序时出现错误:

It fails with the following output:

有人知道为什么 cmake 在编译测试程序时出现问题吗？
最佳答案
我认为您没有配置mbedtls，以便为裸机系统构建它。一些默认选项需要禁用，因为您的目标不是通用操作系统:(没有文件系统，因此标准 BSD 套接字接口(interface)，...)。
这就是为什么您无法编译测试程序的原因，以及为什么您需要通过在 cmake 构建命令中指定 -DENABLE_TESTING=OFF 来禁用它们的编译。
请参阅 mbedtls-2.25.0/include/mbedtls/config.h 中的大量有用注释，以获取有关各种可用配置选项的更多详细信息。
下文描述的过程确实有效，您应该能够通过使用它作为工作示例来修改您自己的构建过程。
