Configure Ruby with option --enable-shared for Rice

[kojix2]

Hello.
Thank you for developing a great library.

I wrote an article at Qiita about trying mnist on Torch-rb. (Japanese)

I had to reinstall the ruby for rice.

• Ubuntu 19.04 rbenv ruby 2.6.5

CONFIGURE_OPTS="--enable-shared" rbenv install 2.6.5

Other than that, there was no problem.

Thank you. And good luck!

Awesome, thanks @kojix2!

How did you install rbenv? --enabled-shared is the default in newer versions.

Also, added the link to the readme :) Let me know if there's something better than 日本語版.

How did you install rbenv?

I installed rbenv according to the README, so I don't think I did anything unusual. Maybe.

added the link to the readme

Wow. It's just a small blog post. It's nothing. Thanks ! 日本語版 is fine.

When you say the readme, are you referring to the GitHub checkout method? Also, how did you install ruby-build?

Edit: maybe more importantly, did you install it recently or over a month ago?

Yes.

Did you install it recently or over a month ago?

Yes. Now I found the commit below in ruby-build.

It was because I built Ruby more than a month ago. Thanks.
