Undefined method 'header' for nil:NilClass

[AlectronikForge]

I tried to install and run TenderJIT but it won't start with following error upon rake compile:

/usr/bin/ruby -I lib misc/build-ruby-internals.rb 65822 /root/GitHub/tenderjit/misc/ruby_internals.rb:310:in read_dwarf': undefined method header' for nil:NilClass (NoMethodError) from /root/GitHub/tenderjit/misc/ruby_internals.rb:321:in block in each_compile_unit' from /root/GitHub/tenderjit/misc/ruby_internals.rb:318:in open' from /root/GitHub/tenderjit/misc/ruby_internals.rb:318:in each_compile_unit' from /root/GitHub/tenderjit/misc/ruby_internals.rb:114:in process' from /root/GitHub/tenderjit/misc/ruby_internals.rb:381:in get_internals' from misc/build-ruby-internals.rb:435:in <main>' rake aborted!

When commenting that line out, the same error occurs for line 276. I'd really like to try this project out, so any help is appreciated!

How did you install Ruby? TenderJIT needs the DWARF information from the Ruby installation. It sounds like it might be missing in yours.

Can you paste the output of this:

$ ruby -e'puts File.join RbConfig::CONFIG["prefix"], "lib", RbConfig::CONFIG["LIBRUBY_A"]'

As well as this:

$ dwarfdump $(ruby -e'puts File.join RbConfig::CONFIG["prefix"], "lib", RbConfig::CONFIG["LIBRUBY_A"]') | head -15

Thanks!
