Running configure: error: wrong libh3 is required or lib not found

[ArniJohannesson]

Followed latest install instructions:

https://h3geo.org/docs/installation

I am on Ubuntu Focal. Next, running ./configure as per the php-h3 install instructions, I get a failure with the message:

... Stuff ...
checking for PHP extension directory... /usr/lib/php/20190902

checking for degsToRads in -lh3... no
configure: error: wrong libh3 is required or lib not found

Has the H3 library changed too much so this binding no longer works, or is there something else going on, like binaries not being where they are supposed to or something?

As an aside, I cannot find the geoToH3 binary anywhere on my system - instead I got:

Hi @ArniJohannesson I will bring up those instructions in the next meeting because they are slightly wrong for those installing the C library directly (and not using one of the officially supported bindings). The master branch is currently being worked on for a major version change (to 4.0.0) that has changed the terminology to be more uniform and allow standardization of terminology with DGGRID in the future (hopefully).

What you want to do after the git clone is to run git checkout v3.7.1 to get the most recent tagged release of the C code, not the in-development changes.

I don't know if that will fix things for you with this binding, though. We don't use php and this repository hasn't been updated in 2 years; you may need to check out an earlier version of H3 to get it working here?

I gave up on this and decided to implement the H3 functionality we need in Nodejs instead. Thanks!
