Trying to install ruby and get error - "fatal error: 'stdlib.h' file not found #include < stdlib.h> "

When trying to install ruby via terminal I get the following error.

" ./cryptlib.h:62:10: fatal error: 'stdlib.h' file not found #include < stdlib.h>

1 error generated. make[1]: *** [cryptlib.o] Error 1 make: *** [build_crypto] Error 1 "

My XCode is up to date.

Please let me know what I should do.

Thanks!

have you installed the xcode developer tools? try opening terminal and running the following command:

xcode-select --install

a window should pop up about installing the command line tools. you most likely need to install these to install rails/ruby. install them then try installing ruby again

Yes exactly - only not sure if it's for Mavericks only. Also alternatively, (I remember I started with)

gcc --version

And, this is my question, is Xcode Command-line Tools another thing, or the same, from Xcode Development Tools?

Isaac, sounds like you're on OS X. What do you see when typing "ruby -v" at the command line?
