Solved: Juniper NED: Erlang - error writing file

DTtb · ‎01-25-2021

Hi all,

during the compile of Juniper NED, I encounter an issue from Erlang compiler.

It looks like, that Erlang cannot find a file.

The directory is owned by user root inside a Docker container.

Maybe someone has a hint to fix it.

OS: CentOS 7 (7.9.2009)

Java: 1.8.0_275

Ant: 1.9.4

NED: juniper-junos-nc-4.6 (Version 4.6.14)

NSO-Version: 5.2.3

Log of compile run:

I found my mistake.

I used Git to track the changes for the dir.

But after a "make clean" the

juniper-junos-nc-4.6/erlang-lib/ec_junos_ext_vlan/ebin

directory is empty. Git not commt empty directories.

Therefore the directory was missing and the Makefile didn't create this dir and the error was thrown. After re-creating of ebin dir the compilation works.

A empty .gitkeep file should keep the directory in Git context.
