在KAA中使用ESP8266 SDK编译错误0.10.0

Question

我已经根据this document构建了ESP8266 SDK。

但编译报告显示下面的错误。 Attachemnt是ld文件。你能帮我解决吗？非常感谢！

要正确地构建C SDK应用程序的ESP8266平台，禁止与-DWITH_ENCRYPTION=OFF CMake的命令行参数的加密功能。

此外，禁用未使用的SDK扩展。例如，要禁用通知扩展，您应该将-DWITH_EXTENSION_NOTIFICATION=OFF传递给CMake。有关C SDK构建配置的更多信息，请参阅此文件 - https://github.com/kaaproject/kaa/blob/master/client/client-multi/client-c/CMakeLists.txt

此外，请不要忘记将-DCMAKE_BUILD_TYPE=MinSizeRel传递给CMake，以便生成的可执行文件将针对大小进行优化。
