----------------------------------------
Feature #14656: Improve mkmf error message when ruby.h is missing
https://bugs.ruby-lang.org/issues/14656
* Author: peyremorgan (Morgan Peyre)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
----------------------------------------
Without the development tools, trying to install most gems results in the following error :
~~~
mkmf.rb can't find header files for ruby at #{$hdrdir}/ruby.h
~~~
Copy-pasting the error into a search engine yields numerous versions of the same solution : installing the ruby development environment (package `ruby-dev` or `ruby-devel` on most Linux distributions) solves the issue.
Maybe the error message could hint at this solution? I found the following line further down in the same file that could be added after the current error message :
~~~
You have to install development tools first.
