-# This is a not quite automated Makefile to generate the Solaris

-# libraryCaller.java program must be compiled. Next, javah is called
-# on the class file to generate the needed header file for the jni
-# code. Then, 2 Solaris executables are generated in separate
-# directories, a default one meant to be pointed to by LD_LIBRARY_PATH
-# (this function returns 0) and another one for the data model
-# specific LD_LIBRARY_PATH (this function returns the size of integers
-# in the data model, 32 or 64). A better makefile would run, say
-# isainfo -v, and generated binaries for all supported data models.
-# To do this a mapping would be needed from data models to
-# architecture dependent compiler options; e.g. 64 bit on sparc =>
-# -xarch=v9. Also, the settings for JINCLUDE, JAVAC, and JAVAH should
-# come from the current build. The C compiler should be the one
-# approved for the build. To be extra safe, the binaries should be
