[SOLVED] Where to get liber.h file/package for Lua?

Where to get liber.h file/package for Lua?

I'm trying to install the lualdap via luarocks with sudo luarocks install lualdap, but I am greeted with

Installing https://luarocks.org/lualdap-1.2.4.rc1-0.src.rock

Error: Could not find header file for LBER
  No file lber.h in /usr/local/include
You may have to install LBER in your system and/or pass LBER_DIR or LBER_INCDIR to the luarocks command.
Example: luarocks install lualdap LBER_DIR=/usr/local

Notes:

I am on Lua 5.3.
I've installed OpenSSL and HTTP.
I've tried the LBER_DIR=/usr/local parameter.

I've looked around for what rock file I need to download to get this lber.h file, but am not having any luck with it. How can I get this lber.h file?

Solution

lber.h is not a file specific to Lua, but part of a library that needs to be installed on your system in order for the lualdap rock to be compiled.

On Ubuntu-like systems, you can install it with:

sudo apt-get install libldap2-dev
