Exception after setting CURLOPT_HTTP_VERSION to CURL_HTTP_VERSION_2_0

[osanwe]

Hello!

I tried to built the first example, and it works well. Next I tried to add http2 support to it:

easy.add<CURLOPT_HTTP_VERSION>(3);

and after that I got the follow error:

terminate called after throwing an instance of 'curl::curl_easy_exception'
  what():  std::exception
Aborted (core dumped)

Hi @osanwe
Well, I noticed that, if you put

easy.add<CURLOPT_HTTP_VERSION>(3);

inside a try-catch block, the error is: Unsupported protocol.
P.s.: you can use CURL_HTTP_VERSION_2_0 (or CURL_HTTP_VERSION_2), if you want, instead of 3.

Well, thanks!
Is there a way to use http2 without rebuilding libcurl? Unfortunately Mer SDK hasn't cURL with http2.

I really don't know, but you could try asking this question in the libcurl mailing list or contacting libcurl creator. Let me know!

Since this is not a bug of curlcpp library, I will close the issue.
