How do you install (build) Ruby 1.9.3 on OSX Lion?

Question

I've been working on installing Ruby on my mac, OSX Lion. I've installed XCode, GCC, Readline, Homebrew, and JewleryBox, but I have no idea what's going on. Any pointers?

Here's what my terminal says?

There has been an error while running make. Halting the installation.

Edit: After installing macports and apple's 4.2 gcc (thanks guys), i'm getting this:

Edit: Jared. When I add --with-gcc=clang , the log looks like

make: *** [.rbconfig.time] Abort trap: 6

Edit: Thanks for all your help guys :), finally figured it out. Here's the sparknotes version of what I did:

(If you're unfamiliar with the command line, http://jewelrybox.unfiniti.com/ is a godsend).

1. Install RVM (https://rvm.beginrescueend.com/ ) It manages multiple versions of Ruby at the same time on one comp (mac/linux only). Makes folders that different versions of Ruby can work independently in (from what I understand).

2. Get XCode (https://developer.apple.com/xcode/ ) Needed to compile code together. But, you also need gcc, which doesn't come packaged with the latest version of XCode. Soo....

3. Went here (https://developer.apple.com/downloads/index.action ) and downloaded "Command Line Tools For XCode" Simple and straightforward to run.

4. Installed Macports (http://www.macports.org/install.php ) so that I could...

5. Install make (port install make ) through the terminal. Not sure what it does, but the terminal gave and error before installing, and no error afterwards.

And NOW we're ready to rock :)

run (rvm install 1.9.3) Hang out for a bit. It takes a while.

Then (rvm 1.9.3 --default)

Then (gem install rails) To install Ruby on Rails. This also takes a while.

Once I was set up with rails 3, I made a test app. (rails new tester) - builds the directory (cd tester)- moves to the new directory

(rails server) -sets up the server

Then, hop on the internet and visit (http://localhost:3000). If all goes well, you should see welcome to rails in your browser.

Answer 1

I just ran into this issue myself, and it seem to be an issue with how ruby-1.9.3-125 works with clang. Once I run it against gcc it worked like a charm.

Check to make sure you have the actual gcc installed with which gcc-4.2. If it isn't you'll need to install Xcode or something akin to the os x gcc installer. If it is installed running rvm install 1.9.3 --with-gcc=gcc-4.2 is what did the trick for me.

Answer 2

You can theoretically use the clang compiler that ships with modern XCode to build Ruby 1.9.3, but it isn't officially supported. Given you hit a segfault, my guess is that you hit some bug with the pairing.

Instead, install the apple GCC 4.2 - should be the apple-gcc42 brew - and install with CC=/path/to/apple-gcc-4.2 rvm install 1.9.3 instead.
