Bug 666408 – dev-ruby/rubygems-2.7.7-r1 - undefined symbol: EC_GROUP_new_curve_GF2m

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description Francesco Turco 2018-09-17 12:32:23 UTC]

When running the "gem update" command on my Gentoo system I get the following error message:

> ERROR:  Loading command: update (LoadError)
> 	/usr/lib64/ruby/2.5.0/x86_64-linux/openssl.so: undefined symbol: EC_GROUP_new_curve_GF2m - /usr/lib64/ruby/2.5.0/x86_64-linux/openssl.so
> ERROR:  While executing gem ... (NoMethodError)
>     undefined method `invoke_with_build_args' for nil:NilClass

The following command returns nothing:

> $ grep -r EC_GROUP_new_curve_GF2m /usr/include/openssl

I wonder if the problem is due to the fact that I recently enabled the "bindist" USE flag, globally... Does rubygems need -bindist on openssl?

-----------

$ emerge -pv ruby rubygems openssl

These are the packages that would be merged, in order:

Pretty safe bet that bindist is causing this because in openssl its main purpose is to avoid including Elliptic Curve code that may be patent-encumbered.

Not sure why this would cause errors though. Did you recompile dev-lang/ruby after changing openssl?

Rebuilding dev-lang/ruby fixed the problem! Thank you! Anyway I wonder why revdep-rebuild didn't detect this problem...
