@nikosft #include "coap.h" where is it ?

Hello sir,

When I ran the client and server file as per your instruction, I got the following errors.

1. ‘coap_pdu_t {aka struct coap_pdu_t}’ has no member named ‘hdr’
2. ‘coap_context_t {aka struct coap_context_t}’ has no member named ‘hdr’

I resolved it error by removing hdr.

3. ‘coap_pdu_t {aka struct coap_pdu_t}’ has no member named ‘id’

I resolved it by adding tid instead of id.

4. ‘coap_context_t {aka struct coap_context_t}’ has no member named ‘sock’

I already checked the code sock->fd replaces it. So, I did, but still, it is showing me the same error.

I am using these example for testing only. I have to build my case based on this.

Thanks
Vishal

How about a libcoap client?

Hi,
I did the instructions exactly but I can't proccede because "make" throws the error on the issue's title.
I did and I received the follwing :

You can now run 'configure --help' to see possible configuration options.
Otherwise process the configure script to create the makefiles and generated helper files.
