From: "tenderlovemaking (Aaron Patterson)" Date: 2013-07-10T02:55:56+09:00 Subject: [ruby-core:55881] [ruby-trunk - Bug #7227][Rejected] failed to build native extension for bcrypt-ruby gem under cygwin on windows xp Issue #7227 has been updated by tenderlovemaking (Aaron Patterson). Status changed from Assigned to Rejected Looks like Aman fixed this in the bcrypt repository. It is not a bug in MRI, but a problem with the bcrypt-ruby extension. ---------------------------------------- Bug #7227: failed to build native extension for bcrypt-ruby gem under cygwin on windows xp https://bugs.ruby-lang.org/issues/7227#change-40381 Author: apolishch (Abraham Polishchuk) Status: Rejected Priority: Normal Assignee: tenderlovemaking (Aaron Patterson) Category: build Target version: next minor ruby -v: 1.9.3-p286 Backport: I am setting up a testing agent on Windows XP for a Rails App. This question was posted by me on Stackoverflow, where, members of the community suggested that this was in fact a Ruby Bug I should report here. For consistency purposes, the original StackOverflow Post can be found here: http://stackoverflow.com/questions/13057452/failed-to-build-native-extension-for-bcrypt-ruby-gem-under-cygwin-on-windows-xp To enforce consistency between Agents, I am installing it through Bundler with RVM with Cygwin. The following is the result of running bundle install in the project directory(EDIT: Note that running gem install bcrypt-ruby produces identical output): Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. /goBaltoEngineering/.rvm/rubies/ruby-1.9.3-p125/bin/ruby.exe extconf.rb creating Makefile make compiling bcrypt_ext.c compiling crypt.c compiling crypt_blowfish.c compiling crypt_gensalt.c compiling wrapper.c In file included from wrapper.c:27:0: /goBaltoEngineering/.rvm/rubies/ruby-1.9.3-p125/include/ruby-1.9.1/ruby/backward/util.h:2:2: warning: #warning use "ruby/util.h" instead of bare "util.h" linking shared-object bcrypt_ext.so bcrypt_ext.o:bcrypt_ext.c:(.text+0x29): undefined reference to `_ruby_bcrypt' collect2: ld returned 1 exit status Makefile:207: recipe for target `bcrypt_ext.so' failed make: *** [bcrypt_ext.so] Error 1 Gem files will remain installed in /goBaltoEngineering/.rvm/gems/ruby-1.9.3-p125@togo/gems/bcrypt-ruby-3.0.1 for inspection.
