Trying to install ruby-oci8 with jruby gemset. It's giving me below error
I've tried to use export JRUBY_OPTS="--1.9 -Xcext.enabled=true" as suggested in other similar questions with no luck.
$ jruby -S gem install ruby-oci8

We can use JDBC, instead of oci8. oci8 needs c extenssions which has been deprecated in jruby.

I am getting the following error and dont know how to solve this. Can someone simplify this process?
My Jruby is installed in
C:/jruby-1.7.13/bin
my project is in
C:/Users/myname/downloads/projectdirectory
The error is when I do
bundle install

C- extensions are not really supported in JRuby and were actually dropped in the 1.7.x line ...
thus despite the message mentioning -Xcext.enabled=true won't help you!
since it's pg you're trying, there's a jruby alternative that uses a Java API instead of C pg_jruby, alternatively if you're using active-record look for activerecord-jdbc-adapter + jdbc-postgres

I guess rubyrhino should solve the problem - https://github.com/cowboyd/libv8/issues/131
I've recently started exploring JRuby using Joe Kutner's book "Deploying with JRuby", but I've hit an issue when trying to install the jruby-lint gem. Below is the output from my attempts, including the version numbers of Java, JRuby, and my OS.
I don't understand the output, especially why nokogiri wouldn't install as a jruby-lint dependency, but would install ok on its own. While the jruby-lint gem is now reported as having installed correctly, it has not delivered a jrlint executable/script to use, and I don't know where to go from here. Any ideas?

I ran into a very similar issue, also while working through this book. Updating Rubygems solved it for me. Perhaps try:
jruby -S gem update --system
It's interesting that it tries to install the Ruby(not JRuby) version of Nokogiri cause it tries to install C extensions.
I think if you install the same version required by jruby-lint which is nokogiri-1.6.0.rc1, problem will be solved.
Neither solution here works for me on Windows. jruby -S gem install nokogiri
installs nokogiri-1.6.0-java
If I download the gem from https://github.com/jruby/jruby-lint and build it myself it leaves the gem folder empty at jruby\lib\ruby\gems\shared\gems\jruby-lint-0.4.1
And it won't make a bat file for running it in the /bin dir. I don't think this gem is ready for windows. Could it be that I'm trying to install it on BitNami stack? I haven't tried it with a regular install of JRuby.
In case updating Rubygems doesn't work, try:
gem install nokogiri
This will install nokogiri-1.6.0-java
then again:
gem install jruby-lint
and you're good to go.
I'm trying to move a small Sinatra app I have going on an Ubuntu box to a redhat box.
While installing gems, I get a "Can't build native extension" error while trying to install the gem dm-mysql-adapter.
I have mysql-devel installed, which I believe is the required library, but it doesn't seem to work.
All the info I can find online is for Ubuntu and says installing libmysqlclient-dev (which doesn't exist for Redhat; again, I believe mysql-devel is the appropriate package).
Any advice for someone using redhat?
you have the correct package "mysql-devel-5.1.48-1" but the gem installs fine on my centos5 box without the package installed, you could try the ruby-mysql gem instead.

I'm using Vista. Has anybody gotten this to work? Any help would be greatly appreciated.
hhh
JRuby does not support native extensions. A related stackoverflow question is here.
Second try:
There is bug report and a workaroud: set rake=jruby -S rake.
