HowToBuildRjb

Preparation

• download and install JDK 5.0 or later (not JRE)
  • (Win32, Win64, Solaris, Linux) http://java.sun.com/javase/downloads/index.jsp
  • (OS X --- J2SE package means JDK) http://developer.apple.com/java/
• 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=/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.
