Ruby 2.6

Just switched to Ruby 2.6.0 from 2.5 on Mac OS

gem install debase --pre
Building native extensions. This could take a while...

I also have the same issue and had to pin ruby to 2.5

Same issue here, returned to 2.5

The error with "FALSE not defined" seems to be in the debase-ruby_core_source gem v0.10.4. I edited this file:

/usr/local/rvm/gems/ruby-2.6.0/gems/debase-ruby_core_source-0.10.4/lib/debase/ruby_core_source/ruby-2.6.0-p0/vm_insnhelper.h

and added the line:

#include "regenc.h"

before this line:

RUBY_SYMBOL_EXPORT_BEGIN

and this fixes the problem building debase v0.2.3.beta2 for me.

I could not find any sensible way to compile vm_insnhelper.h from 2.6. However, it seems that it's not really needed for debase, I've cleaned up the includes, now it should work. Please check out 0.2.3.beta3.
