Issue #8130 has been reported by agarie (Carlos Agarie). ---------------------------------------- Backport #8130: ArgumentError being thrown when using find_library https://bugs.ruby-lang.org/issues/8130 Author: agarie (Carlos Agarie) Status: Open Priority: Normal Assignee: Category: Target version: Hi, I'm a contributor to SciRuby and I'm currently working on NMatrix, a numerical linear algebra library that uses LAPACK and ATLAS. I was compiling it with Ruby 2.0.0p0 installed through RVM and had a problem I didn't have when using 1.9.3: /Users/carlosagarie/.rvm/rubies/ruby-2.0.0-p0/lib/ruby/2.0.0/mkmf.rb:893:in `%': too many arguments for format string (ArgumentError) from /Users/carlosagarie/.rvm/rubies/ruby-2.0.0-p0/lib/ruby/2.0.0/mkmf.rb:893:in `block in checking_for' from /Users/carlosagarie/.rvm/rubies/ruby-2.0.0-p0/lib/ruby/2.0.0/mkmf.rb:337:in `block (2 levels) in postpone' from /Users/carlosagarie/.rvm/rubies/ruby-2.0.0-p0/lib/ruby/2.0.0/mkmf.rb:307:in `open' from /Users/carlosagarie/.rvm/rubies/ruby-2.0.0-p0/lib/ruby/2.0.0/mkmf.rb:337:in `block in postpone' from /Users/carlosagarie/.rvm/rubies/ruby-2.0.0-p0/lib/ruby/2.0.0/mkmf.rb:307:in `open' from /Users/carlosagarie/.rvm/rubies/ruby-2.0.0-p0/lib/ruby/2.0.0/mkmf.rb:333:in `postpone' from /Users/carlosagarie/.rvm/rubies/ruby-2.0.0-p0/lib/ruby/2.0.0/mkmf.rb:891:in `checking_for' from /Users/carlosagarie/.rvm/rubies/ruby-2.0.0-p0/lib/ruby/2.0.0/mkmf.rb:969:in `find_library' from ../../../../ext/nmatrix/extconf.rb:124:in `<main>' The complete output can be found in this gist: https://gist.github.com/agarie/5202139#file-gistfile1-sh. And extconf.rb:124 contains the following: find_library("lapack", "clapack_dgetrf", "/usr/local/lib", "/usr/local/atlas/lib") I couldn't find a note on the 2.0 changelog about something that could have "broken" it. I can get it working by commenting lines 893 and 896 of mkmf.rb, which are explicitly shown in this gist: https://gist.github.com/agarie/5202139#file-gistfile2-rb. And this is the mkmf.log: https://gist.github.com/agarie/5202139#file-mkmf-log Regarding ruby version: $ ruby -v ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-darwin11.4.2] I also couldn't find a similar bug on the issue tracker or on Google. And to reproduce the error: $ git clone git://github.com/SciRuby/nmatrix.git $ cd nmatrix $ bundle install $ bundle exec rake compile It might give other problems because of the libraries necessary for installation. I'm trying to come up with a simpler script that reproduces this error -- I'll update this ticket as soon as I'm successful. Another thing is that when using 1.9.3-p392 and doing the same set of steps, it works correctly. Thanks for your time.
