While installing ruby with:

rvm install 2.1.2

I am getting this error.

And I have also tried building ruby 2.1.2 and other versions as well from source, but I am getting the same error while running:

./configure


OSX Version: 10.14.2 (18C54)
Rvm Version: 1.29.4

This error started coming up after I upgraded to OSX Mojave.

Try renaming your /usr/local/include to /usr/local/include_old & then try again. – Aaditya Maheshwari
Thanks @AadityaMaheshwari that seemed to work for me. Can you explain why? – matt freake

As noted in the comments, renaming the /usr/local/include directory does solve this particular issue. This works because the installer script can no longer find the file causing the problem, previously located in the folder formerly known as /usr/local/include.

While this works, it is likely you'll later encounter issues with homebrew formulaes (stuff already installed on your machine via homebrew).

Solution:

Although this may not always be the case, I simply needed to delete /usr/local/include/stdint.h
