Re: How to use shapeII in 2.18 on Windows 10?

Hi Saul,

I need some more specifics to fully address your issues.

Which repository? Unfortunately there are currently two where it can be
found.

I don't fully understand what you are referring to. Which usage guide?

Again, which documentation exactly?

Yes, there is a substantial breaking change between 2.19.21 and 22,
which required to implement certain things conditionally all over the
place. And at some point we had to decide (there was a discussion about
it) to drop support for LilyPond 2.18 - also in the naive belief that
it couldn't be too long until 2.20 would become the new stable version
...

If it really is (and I assume it is because Janek implemented it on
2.17, IIRC) you will be able to use it. Try including the "module.ily"
file directly, and if that doesn't work out of the box you should be
able to copy and paste everything the traditional way.

Please include the complete file, or a GitHub link to it, so we can
talk about the same thing.

As said, I don't know what file exactly you are trying to compile, and
I'm wondering why you have even reached a point where this specific
file is searched.
But what I *do* see is that you haven't told LilyPond where to look for
openLilyLib. As said also I don't know exactly what documentation you
are referring to, but if you have seen any documentation detailing
something about directory structure it should also include the
instruction which directory to add to LilyPond's search path.
