HttpServer.cpp compilation error

[prasad-dot-ws]

I'm trying to compile cpp_utils components, But it gives me this error,

CXX build/cpp_utils/HttpServer.o
/Users/Prasad/esp/https_request/components/cpp_utils/./HttpServer.cpp: In member function 'virtual void HttpServerTask::run(void*)':
/Users/Prasad/esp/https_request/components/cpp_utils/./HttpServer.cpp:195:25: error: exception handling disabled, use -fexceptions to enable

Howdy my friend. The cpp_utils now requires the very latest ESP-IDF and the latest toolchain. I suspect that you are running an older version of the ESP-IDF and toolchain?

The ESP-IDF I am using was pulled from here:

https://github.com/espressif/esp-idf

and the tool chain from

http://esp-idf.readthedocs.io/en/latest/get-started/index.html#setup-toolchain

Hi Sir! Thank you for your response. I was trying to update the xtensa toolchain and i stuck here, Would you mind helping me out there?

Sorry ... I have no skills on Mac. What I normally recommend is that folks work on Linux (my favorite is Ubuntu). That is the platform that I believe that the majority of ESP32 programmers work on and where you will find the majority of support. I think you can install and run Ubuntu using Virtual Box on your Mac.

I had the same issue when trying the project. I fixed it by running "make menuconfig", go into "compiler options" and enabled C++ Exception handling.

Thank you @joehui ... that's a great catch. That looks like a new option. First there was no exception handling, then it was added by default and now its optional. Its all good as the ESP-IDF v3.0 is still pre-release.

Sadly its not very helpful what they did, but nice catch. Helped me to avoid headache today.
