ruby-debug install error: failed to build gem native extension

Question

I\'m running 1.9.2 with rails 3.

I\'m using rvm.

I did:

sudo gem install ruby-gem

and got:

Building native exte         


        

Answer 1

For windows, search your ruby dir for vm_core.h and then use that dir as your include path. For me, that's

gem install ruby-debug-base19 -- --with-ruby-include=C:\JRuby\lib\native\include\ruby-1.9.3-p392

Then I had to check:

C:\JRuby\lib\ruby\gems\shared\gems\linecache19-0.5.12\ext\trace_nums\gem_make.out

and move ruby/ruby.h into the include directory above.

Now I have some other error, fix it a bit later...
