Failing to build bcrypt-ruby when installing from a Rails application

[balinterdi]

When I try to install the gem from inside a Rails application (more precisely, a Rails engine) it fails with the following error message:

/Users/balint/.rbenv/versions/1.9.3-p392/bin/ruby extconf.rb 
creating Makefile

make

compiling crypt.c

make: *** No rule to make target `-/ruby/1.9.1/gems/bcrypt-ruby-3.0.1/lib/bcrypt_ext.bundle', needed by `install-so'.  Stop.

However, I succeeded in installing the gem explicitly with gem install bcrypt-ruby -v '3.0.1'.

The ruby version I used was 1.9.3-p392.

gcc -v outputs the following:

Using built-in specs.

Thread model: posix
gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

AFAIK I don't have any bundle option or env. var that could cause the compilation process to be modified.

Could you tell me what the difference between the installation processes could be and how should the problem be dealt with?

Thank you.

Can you include the generated Makefile that's causing a make error?

Also created a gist with this Makefile

Strange:

    RUBYLIBDIR = /Users/balint/code/rails/wlb/!binary |-/ruby/1.9.1/gems/bcrypt-ruby-3.0.1/lib$(target_prefix)

[tmm1]

I don't see anything in the code that would be causing this. Does this weird !binary |- thing happen in other gems too?

[balinterdi]

The weird !binary |- thing came from a .bundle/config file in the project's directory:

$ bundle config
path
Set for your local app (/Users/balint/code/rails/wlb/.bundle/config): "!binary |-"

I'm not sure how that file was generated and put there but deleting it and rerunning bundle install worked flawlessly.

Thanks a lot for helping me sort that out.
