Error: extconf failed, exit code 1 [Ruby on Rails]
managed to solve this. I had upgraded to OS Mavericks recently and problem came up.
Have tried gem install bcrypt-ruby -v '3.1.2' in terminal but encountered same problem.
Thereafter, went to install Xcode on App Store as running Xcode-select --install in terminal failed as well (program can't be found).
Thus I chanced upon this thread and followed advice to run sudo ln -s /usr/bin/llvm-gcc /usr/bin/gcc-4.2 in terminal.
Thread: gem install pg doesn't work on OSX Lion
Thereafter I ran gem install bcrypt-ruby -v '3.1.2' and bundle install in terminal and all good for now. Hope this works. Actually I don't know what I am doing but hopefully it works. Can someone enlighten me what I am actually doing?

Am new to programming and Ruby on Rails so kindly assist. Thanks!

rkamun1 about 10 yearsI'm not certain, but it seem that updating to xcode 5 gives the /usr/bin/llvm-gcc file while atomic is looking for the /usr/bin/llvm-gcc-4.2 file. When installing xcode 4, it symlinks /usr/bin/llvm-gcc-4.2 to /usr/bin/gcc-4.2. What you did now is symlink /usr/bin/llvm-gcc- to /usr/bin/gcc-4.2.
