Re: [jruby-user] JRuby 1.7.17: getppid unsupported or native support failed to load

Hi Tom,

So it's picking up the library as "libcrypt.so.1" if it's installed in /lib
(as it is in Ubuntu 10.04), but not if it's installed
under /lib/x86_64-linux-gnu (as it is in Ubuntu 12.04).

I can get it to load if I do either:

ln -s /lib/x86_64-linux-gnu/libcrypt-2.15.so /lib/libcrypt.so.1
or
ln -s /lib/x86_64-linux-gnu/libcrypt-2.15.so
/lib/x86_64-linux-gnu/libcrypt.so

ie link from /lib to /lib/x86_64-linux-gnu/ as libcrypt.so.1 or create the
link as simply libcrypt.so under /lib/x86_64-linux-gnu

It feels to me like that's not going to be the root cause, but rather would
indicate a mis-configuration of the machine somewhere.

Is it possible to get jruby working with this configuration (eg by using
fall-backs), or do we consider this a machine configuration problem, and
fix it on our production servers?

Thanks,

Michael
