i have installed jruby , jvm.

you're trying install gem native extensions inside java version of ruby: bad idea...

i found pure java implementation of scrypt algorithm @ https://github.com/wg/scrypt.

you need download jar file maven (http://search.maven.org/remotecontent?filepath=com/lambdaworks/scrypt/1.4.0/scrypt-1.4.0.jar), add library path or require jar in code.

next write wrapper imitate scrypt behavior use drop-in replacement in ruby/rails code.

alternatively, remove scrypt bits , use java library directly. here's snippet tested in jirb (1.7.20)...

>> require 'java' => true >> require './scrypt-1.4.0.jar' => true >> java_import 'com.lambdaworks.crypto.scryptutil' => [java::comlambdaworkscrypto::scryptutil] >> passwd,n,r,p = 'secret',16384,8,1 => ["secret", 16384, 8, 1] >> hashed_passwd = scryptutil.scrypt(passwd,n,r,p) => "$s0$e0801$mzcxaobvz7kavu6e5hv0cg==$rax9adwveyze5jrl+j1npibsepnabecvdr7drddpgmw=" >> scryptutil.check(passwd,hashed_passwd) => true >> scryptutil.check('wrong password',hashed_passwd) => false
