!How To Build Rjb

!! Preparation

*download and install JDK 5.0 or later (not JRE)
**(Win32, Win64, Solaris, Linux)
**(OS X --- J2SE package means JDK)
*set JAVA_HOME environment variable, this variable must points the root of the JDK directory.
**extconf.rb searchs jni.h in [JAVA_HOME]/include
**OS X, type 'export JAVA_HOME=JAVA_HOME=/Library/Java/Home' JAVA_HOME=/Library/Java/Home' on Terminal.App
*(recommanded, but not required) add $JAVA_HOME/bin: (or %JAVA_HOM%\bin; for Windows) on top of the PATH environment variable's current value.

!! build rjb with gems (not MSWin32)

gem install rjb

*The installation process (extconf.rb) searchs $JAVA_HOME/include/jni.h.

!! MSWin32

If you are using ActiveScriptRuby or One Click Installer, or such MSVCRT.DLL depends binaries, You don't need MSVC++ for building Rjb.
Because the mswin32 version of gem already contains the pre-build rjb's DLL.
So, you can simply install mswin32 version of the gem into the system.

But, JDK is also required.

!! Compile in Cygwin by hands

* J2SDK 5.0 are necessary to compile it in Cygwin.
* Define a JAVA_HOME environment variable in personal initialization file(~/.bash_profile, ~/.bashrc, etc)
** ex(bash)) export JAVA_HOME=/cygdrive/c/j2sdk1.5.0_07
* add $JAVA_HOME/bin into the PATH envirionment variable.
** ex(bash)) export PATH=$JAVA_HOME/bin:$PATH

* Move to the place that unzipped archive. install rjb.
