Unfortunately, it generates more errors of the following:

If I remove CONFIG_POSIX_API=y and reinstate CONFIG_NET_SOCKETS_POSIX_NAMES=y, then this error goes away.

Try adding CONFIG_POSIX_API=y to your prj.conf and see if that helps.

I'm trying to use the Edge Impulse library with the modem library in the nRF9160. In the Edge Impulse library they used the sys/select.h which has some symbols which are redefined in the net/socket_select.h library, causing the conflicts.

Hi,

What are you trying to achieve? What do you need from sys/select.h that you can't get from the zephyr library?
