我想在我的 stm32 项目中使用 mbedtls，但我在构建时遇到了一些问题。我必须用 arm-none-gcc 编译器构建 mbedtls，对吗？我的命令是：（在构建目录中）。

CC=/home/jareeeeczek/Arczbit/Firmware/ProgramingRelated/ARM_GCC/gcc-arm-none-eabi-10-2020-q4-major/bin/arm-none-eabi-gcc CFLAGS='-fstack-protector-strong' cmake -DUSE_SHARED_MBEDTLS_LIBRARY=On ../

我在编译测试程序时出错：

It fails with the following output:

任何人都知道为什么 cmake 在编译测试程序时有问题？

我认为您没有进行配置mbedtls，以便可以为裸机系统构建它。需要禁用一些默认选项，因为您的目标不是通用操作系统：（没有文件系统，所以标准 BSD 套接字接口，...）。

这就是您无法编译测试程序的原因，也是您需要通过-DENABLE_TESTING=OFF在 cmake build 命令中指定来禁用它们的编译的原因。

请参阅大量有用的评论， mbedtls-2.25.0/include/mbedtls/config.h以获取有关可用的各种配置选项的更多详细信息。

下文描述的过程确实有效，您应该能够通过将其用作工作示例来修改自己的构建过程。

toochain.cmake：

set(CMAKE_SYSTEM_NAME Generic)
set(CMAKE_SYSTEM_VERSION 1)
set(CMAKE_SYSTEM_PROCESSOR armv7-m)
set(CMAKE_STAGING_PREFIX /tmp/staging)
set(CMAKE_C_COMPILER /opt/arm/10/gcc-arm-none-eabi-10-2020-q4-major/bin/arm-none-eabi-gcc)
set(CMAKE_CXX_COMPILER /opt/arm/10/gcc-arm-none-eabi-10-2020-q4-major/bin/arm-none-eabi-g++)
set(CMAKE_MAKE_PROGRAM=/usr/bin/make)
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)
set(CMAKE_C_FLAGS=-mtune=cortex-m3)
set(CMAKE_EXE_LINKER_FLAGS " --specs=nosys.specs")

构建过程：

我通过将这些行添加到 mbedtls Cmake 解决了这个问题：

设置（CMAKE_SHARED_LIBRARY_LINK_C_FLAGS“”）设置（CMAKE_SHARED_LIBRARY_LINK_CXX_FLAGS“”）

感谢帮助！
