This is an RPM enhancement request, not an error per se.

Description of problem:

Java packages don't compile, error says can't compile a simple program with the JNI

Version-Release number of selected component (if applicable):


How reproducible:

always...

Steps to Reproduce:
1. install.packages("rJava")
2.
3.
  
Actual results:

compile fails, says JDK not installed.  IT fails because JDK is not in same
place where R package builder had it.

Expected results:


Additional info:

I went to the JGR package team and asked what is up with this. From them, I've
learned that there is a fix.  There is an undocumented feature. Run

R CMD javareconf

and that lets R find your java compiler and headers.  

I wish you would please add this step to the post install script of the RPM.
