add instructions for configure options

Question

add instructions for configure options

DanielKehoe opened this issue 3 years ago · comments

The README says:

You can also specify many other options that will be listed when running ./configure -h.

Can we have an example? It's a great feature and I'd like to see the options but I couldn't figure out how to run ./configure -h.

@citizen428 ?

I think it it necessary to list all configure options in README, but different ruby versions have different config options.
So, we don't do it now.

I was mulling this over for a bit and was wondering if we could add a --configure-help switch to install which would fetch Ruby, extract it and then run ./configure -h.

This would probably entail the following additional work:

Ensure install will use an already downloaded tarball instead of re-fetching.
Add a clean command to remove potential leftover downloads.

What do you think?
