Hi,

You can have a look at this commit which adds explicit casting.

Best regards,

I mean the c library returns an enum but the declaration is int. C++ marks it as error.

C++ version 12.2.0

As full log, do you mean this?:

In file included from C:/ncs/modem_and_sensor/src/ClientLibrary/CDownloadClient.h:5,
from C:/ncs/modem_and_sensor/src/ClientLibrary/CDownloadClient.cpp:1:
C:/ncs/v2.7.0/zephyr/include/zephyr/net/coap.h: In function 'coap_block_size coap_bytes_to_block_size(uint16_t)':
C:/ncs/v2.7.0/zephyr/include/zephyr/net/coap.h:744:16: error: invalid conversion from 'int' to 'coap_block_size' [-fpermissive]
744 | return sz;

Adding this in my CMakeLists.txt

target_compile_options(app PRIVATE -fpermissive)

the error becomes a warning, so I downgrade an error to a simple warning.

Hi,

[quote user=""]I am using download_client library in C++ project. I have to include coap.h[/quote]

Can you show how you do this?

[quote user=""]

when I compile I get this error:

C:/ncs/v2.7.0/zephyr/include/zephyr/net/coap.h:744:16: error: invalid conversion from 'int' to 'coap_block_size' [-fpermissive]

[/quote]

Can you provide full log which shows the error?

[quote user=""]my question is if exists one way to compile without downgrading c++ checks.[/quote]

Can you rephrase this sentence? What do you refer to as "downgrading C++ checks"?

Which C++ version do you use?

Best regards,
Dejan
