Those packages with "glib" in their name are not glib, they use glib. You
would have found it if you did "grep glib2" rather then "grep glib-dev"
glib is the standard C library. It seems unlikely that glib is not
installed. More likely you have a problem with the "include path"

Fails in ./configure with no glib found?
But apt list | grep glib-dev finds quite a list, none of which are
installed:

Peter,
Thank you. I'll be in touch. I need to address a number of other issues
before I can get back to this now.

I've used the 2.2 KW water cooled Chinese spindle with good success for
a few years. As Danny mentioned, the power at low RPM isn't very good.
The largest cutter I use for machining is 1/4" and it's usually 1/8" or
less, but I do use a 1.125" mortising bit to level the spoil board and

Have used a cheap Chinese air cooled 18krpm 3kw spindle for years. You
must drive them off a VFD anyways.
At 3000 rpm you have much less power. Well the torque is probably the
same but power=torque * rpm.
The air cooled is cooled by a shaft-driven impeller, so fan rpm drops to
3000 rpm too

Greetings everyone,
I wish to upgrade a dressing spindle in our EMC grinder. We currently
have a very small DC motor turning a one-inch diamond-studded disc at
about 1500 RPM, with fairly decent results, but my research indicates we
may be better served with a much larger disc and higher RPM.
