Apologies in advance for the long post.
I'm currently using a Makefile to build my shared library. Pursuant to the
R-exts manual, I'd like to switch to a Makevars file or a configure file if
Having never used these types of make utilities before, I'm a bit lost.
My package is quite simple. It only has one source file and one header:
The reason I need help with Makevars is because it needs jni.h from the
user's JAVA_HOME/include and jni_md.h from the user's
In addition, it needs libjvm.so from the user's
I've looked at the SJava package with the idea of using a similar configure
script, but I was hoping I could just get by with a Makevars file rather
than a configure script.
I would appreciate any pointers, as I'm not really sure exactly where to
I suppose if I can find the values of JAVA_HOME, ARCH, and OS_TYPE, then I
can fill in the values I need using PKG_LIBS and PKG_INCLUDE in the Makevars
below is the makefile I'm currently using for your reference.
Thanks in advance,

ARCH = $(shell $(archExpr) )
