Issue #7221 has been updated by davidderyldowney (David Deryl Downey).


mame sorry again for the delay. lots of stuff going on IRL.

I am back to setting L597 in ruby-1.9.3-p286/lib/ruby/1.9.1/mkmf.rb to

return Integer(f.gets)


and attempted a reinstall of kgio v2.7.4 and it works just fine. I was able before to consistently demonstrate the problem, however I no longer am able. I am running ruby-1.9.3-p286 with the falcon patch only, which does not touch that line of code that I can see. The suggested fix was to change the line to:

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

whch I obviously do not have. So I'm unsure what the issue actually is, or why kgio is suddenly working. As per your request, I'm including what I currently have for the mkmf.rb file in question. Its currently online at https://gist.github.com/f687c94fc9df125bb437

Anything else I can provide, let me know.

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)

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.
