Notes on installing libcoap

after installing libcoap. When trying to execute example binary, there is a possibility you will occur error at loading shared libraries,

coap-client: error while loading shared libraries: libcoap-1.so.0: cannot open shared object file: No such file or directory

fix this by adding library path to the linux environment by executing

export LD_LIBRARY_PATH=/usr/local/lib

To make it permanent, you can edit the ldconfig files. First, create a new file such as:

sudo vi /etc/ld.so.conf.d/libcoap.conf

Second, add the path in the created file

/usr/local/lib

Finally, run ldconfig to update the cache.

sudo ldconfig
