How to resolve NRP4 core installation error


while executing command ~/nrp-core-build$ make
i was encountering the following error.

You might have a path issue, like the local Makefile to build libedlut can not be found. We try to reproduce and come back to you.


Hi @DEVA ,

As pointed out by @vonarnim there is an issue with the Edlut installation.

If you don’t need it, it can be removed from the build adding -DENABLE_EDLUT=OFF to the cmake command (see here).

Hope it helps.
