I have tried installing RJB but I keep getting this error :
--
C:\ruby\letter4sure>gem install rjb
Building native extensions. This could take a while...
ERROR: Error installing rjb:
ERROR: Failed to build gem native extension.
c:/ruby/bin/ruby.exe extconf.rb install rjb
checking for jni.h... no
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib
--with-make-prog
--srcdir=.
--curdir
--ruby=c:/ruby/bin/ruby
Gem files will remain installed in
c:/ruby/lib/ruby/gems/1.8/gems/rjb-1.1.3 for inspection.
Results logged to
c:/ruby/lib/ruby/gems/1.8/gems/rjb-1.1.3/ext/gem_make.out

There is an mkmf.log file under
C:\ruby\lib\ruby\gems\1.8\gems\rjb-1.1.3\ext that says :
have_header: checking for jni.h... -------------------- no
"cl -nologo -E -I. -Ic:/ruby/lib/ruby/1.8/i386-mswin32 -I. -IC:\Program
Files\Java\jdk1.6.0_06\include -IC:\Program

Files\Java\jdk1.6.0_06\include -IC:\Program
Files\Java\jdk1.6.0_06\include\win32 /W3 conftest.c -P"
checked program was:
/* begin */
1: #include <jni.h>
/* end */
--------------------
Problem is JAVA_HOME is installed and this is what it says :
C:\ruby\letter4sure>echo %JAVA_HOME%
C:\Program Files\Java\jdk1.6.0_06
When I walk through extraconf.rb I see that it can see jni.h so what is
wrong here?

Yes it is a good installation. I also installed jdk 1.5 and jni.h is indeed located there.

If anyone is still getting this error even after.. -> having JDK installed -> Ruby installed and -> gem install rjb throws error saying checking for jni.h...no open http://rubyforge.org/projects/rjb/ and check the version which doesn''t say (source gem only). Now on command prompt do gem install rjb -v version_number This will install the gem. -- Posted via http://www.ruby-forum.com/.
