I am trying to develop in local Ruby on Rails to a remote DB2 database, I have set global variables pointing to my DB2 cli and db2dsdriver.cfg config file with connection settings.
I have tried also with IBM data server driver package and cli is not detected.
Any advice? How can I install the ibm_db gem and connect to DB2??

I am trying to install rmagick gem on for my rails framework.
I have installed imagemagick and set lib and include path in system variables
But when installing gem install rmagick -- '--with-opt-dir="c:\RailsInstaller\ImageMagick-6.7.9-Q8"' i still get errors.
gem command

Have you considered developing with nitrous io? Developing rails in windows is much harder because there are a lot of errors you have to deal with that others don't and there's not a whole lot of documentation/support. Most answers boil down to something like "windows and rails don't mix".
I read Error Installing Atomic.
But my problem is different:

From atomic web page I read that atomic requires JDK8, I installed it, I am in OS X 10.9.
Some other useful information:
$ /usr/libexec/java_home
/Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home
$ /Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home/bin/java -version
java version "1.8.0-ea"
Java(TM) SE Runtime Environment (build 1.8.0-ea-b114)
Java HotSpot(TM) 64-Bit Server VM (build 25.0-b56, mixed mode)
How should I reference JDK8 when installing this gem? is that the issue?
More useful output?

Any ideas? I've not used Postgre on OSX before, so may be an issue with my install?
It looks like you are trying to install a 64-bit version on a 32-bit machine. Check to make sure that you downloaded the right version for your OS.
I had this exact same problem on OS Lion. I solved it by entering the following (after checking out the postgresql requirements):
rm Gemfile.lock
brew install readline (I'm not sure if this is needed here, but it is a dependency for postgresql and I already had the most up-to-date version of ossp-uuid)
brew unlink postgresql
brew install postgresql (this took about 4 minutes to execute)
bundle install
I hope this helps you out!

conftest.c: In function 't':
conftest.c:5: error: too few arguments to function 'libiconv'
checked program was:
/* begin */
1: #include <iconv.h>
2:
3: /*top*/
4: int main() { return 0; }
5: int t() { iconv(); return 0; }
/* end */
--------------------
I highly recommend using RVM on Mac OS. It's extremely easy to install and it handles downloading and compiling the environment with readline, iconv, openssl, zlib, etc. I can't tell you how many hours it's saved me.

Back to your question - did you try gem install iconv -- --with-iconv-dir=/opt/local ?
