How to upgrade a component library

[leenowell]

Hi All,

I am using the coap library that is bundled with ESP_IDF. I have to upgrade it to the latest version but am struggling to do so. I have tried replacing the existing coap directory with the new one but get compile errors where it can't find the include files (e.g. coap.h). As far as I can see, the file is in the same directory as it was originally so can't see why the compiler doesn't see it. Replacing the new version with the old seems to work as originally.

Anyone have any ideas?

thanks

Lee.
