Hi,

Where I work we have an Ubuntu server. I installed Ruby by compiling the  
1.8.4 sources. According to the standard library documentation at  
[RDoc Documentation](http://www.ruby-doc.org/stdlib/), the openssl library should be included  
in the standard distribution – I need this in order to run SwitchTower.  
However, it doesn’t appear to be there. I cannot require it, and  
checking in /usr/local/lib/ruby/1.8 I cannot see anything to do with  
openssl. Anyone have any ideas? Am I supposed to do something else?

Cheers

I don’t know why it doesn’t build automatically, but whenever I build  
ruby from source, I do the following:

cd ext/openssl  
make install

in order to build the ruby openssl extension.

(On debian, I also recall having needed to build the OpenSSL library  
[not the ruby extension, but the system library] from a source package,  
in order to get the needed header files.)

Hope this helps,

Bill

Probably, you can just apt-get install libssl-dev.

Ahh, indeed, there it is, thanks:

I think I looked for openssl-dev and hadn’t found it.

Thx,

Bill
