我正在尝试使用 ESP32 与 Amazon FreeRTOS 连接，但在构建它时遇到了问题。我正在按照亚马逊网站上的教程（适用于 Windows）做所有事情。错误是

cc1.exe：一些警告被视为错误。

我发现解决方案可能是禁用-werror。为此，我尝试将这一行粘贴 string(REPLACE " -Werror" "" CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}") 到 AmazonFreeRTOS 主文件夹中的 CmakeLists.txt 文件中。没有帮助：/。

我的 CmakeLists.txt 文件如下所示：

cmake_minimum_required(VERSION 3.13)

# Disable in-source build.
if("${CMAKE_SOURCE_DIR}" STREQUAL "${CMAKE_BINARY_DIR}")
    message(FATAL_ERROR "In-source build is not allowed, please use a separate build folder.")
endif()

# Abort if the target board is not supported, i.e., corresponding folder is not present.

endif()

所以请有人告诉我如何禁用 -werror 或其他解决问题的方法。

我遇到了非常相似的问题，在最优秀的 FreeRTOS 人员的帮助下，我尝试了以下方法：

1) 检查 FreeRTOSConfig.h 中的 configSUPPORTSTATICALLOCATION 是否设置为 1。– 否则 nnnCreateStatic() 函数将不可用。

2) 确保 FreeRTOS.h 然后 queue.h 或 tasks.h 包含在有问题的 .c 文件的顶部（视情况而定）。检查警告以识别该文件。
