Subject: [ruby-core:48627] [ruby-trunk - 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)


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


OK, I changed the line back to the original return Integer(f.gets) and attempted a reinstall of kgio under 1.9.3-p286.

The output from the build is still: ruby-1.9.3-p286/lib/ruby/1.9.1/mkmf.rb:597:in `Integer': can't convert nil into Integer (TypeError)

The entire contents of kgio's (v2.7.4) extconf.rb is gist here at: https://gist.github.com/08ae8fef33b610c44e6c  All 53 lines of it.

Anything else I can do please let me know. Sorry for the slow replies, IRL is a bugger hehe.

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.
