Sorry for late reply.

Anyway it is difficult to fix a bug if no one reproduces it.
I'm marking this ticket closed.  Please reopen this if you could repro.  Thanks.

Bug #7221: Unable to compile kgio under 1.9.3 with error: ruby-1.9.3-<plvl>/lib/ruby/1.9.1/mkmf.rb:597:in `Integer': can't convert nil into Integer (TypeError)

Author: davidderyldowney (David Deryl Downey)
Status: Rejected
Priority: Normal
Assignee: mame (Yusuke Endoh)
Category: 
Target version: next minor
ruby -v: ruby 1.9.3p286 (2012-10-12 revision 37165) [x86_64-darwin12.2.0]
Backport: 


The kgio gem is unable to be compiled under 1.9.3-p286. The problem is the same as reported here: https://github.com/wayneeseguin/rvm/issues/1157, specifically the same issue is seen under ruby-1.9.3-p194 as reported here at https://github.com/wayneeseguin/rvm/issues/1157#issuecomment-9045588 

The actual error is: 

ruby-1.9.3-p194/lib/ruby/1.9.1/mkmf.rb:597:in `Integer': can't convert nil into Integer (TypeError)

If L597 of mkmf.rb is modified to say: 

return Integer((v=f.gets) ? v : 0 )

then the problem instantly goes away.
