Ruby Version Manager (rvm)

Installation of rvm on Snow Leopard

There seems to be an issue with the system readline utility which prevents Rubies installed by rvm from being compiled. A possible fix to this is to install your own version of readline.

Errors in the make log:

readline.c: In function ‘username_completion_proc_call’:
readline.c:730: error: ‘username_completion_function’ undeclared (first use in this function)
readline.c:730: error: (Each undeclared identifier is reported only once
readline.c:730: error: for each function it appears in.)
make[1]: *** [readline.o] Error 1

Your own readline

Compile and install your own readline:

curl -O
tar xzvf readline-6.1.tar.gz
cd readline-6.1
./configure --prefix=/usr/local
sudo make install
cd ..

Give rvm another try ...

First you have to remove Ruby versions you tried to compile before:

rvm remove 1.9.1

The following command with a reference to the newly installed newline should do the job:

rvm install 1.9.1 -C --with-readline-dir=/usr/local/
