Can we install C gems in ruby 2.7.0

Question

I just upgraded by ruby to 2.7.0.

And I tried to install the ibm_db gem in windows platform. Installation works fine. When I try to use the gem(like require 'ibm_db') I get the following error

LoadError (126: The specified module could not be found.   - C:/Ruby27/lib/ruby/gems/2.7.0/gems/ibm_db-5.1.0-x86-mingw32/lib/mswin32/rb2x/i386/ibm_db.so)

I have faced this type of error in ruby 2.6 also but when I have set RUBY_DLL_PATH to the ddl which the gem uses it is solved.

But in ruby 2.7 even after setting this variable I get the following error.

Can anyone please help in solving this? ( I have one more doubt:- c gems are supported in ruby 2.7)

Answer 1

The issue is because the binary was pointed to ruby 2.6 binary. So replace it with the latest ruby 2.7 binary and then everything works fine.

Thanks, Akhil

Answer 2

It appears that the ibm_db gem currently does not support Ruby 2.7 yet. The newest Ruby version they support is Ruby 2.6.x.

There is a pull request at https://github.com/ibmdb/ruby-ibmdb/pull/105 which might add support for Ruby 2.7 though.
