AC_PROG_JAVAC tests an existing Java compiler. It uses the
environment variable JAVAC then tests in sequence various common
Java compilers. For political reasons, it starts with the free
ones.
If you want to force a specific compiler:
AC_PROG_JAVAC
You can use the JAVAC variable in your Makefile.in, with @JAVAC@.
*Warning*: its success or failure can depend on a proper setting of
the CLASSPATH env. variable.
TODO: allow to exclude compilers (rationale: most Java programs
cannot compile with some compilers like guavac).
Note: This is part of the set of autoconf M4 macros for Java
programs. It is VERY IMPORTANT that you download the whole set,
some macros depend on other. Unfortunately, the autoconf archive
does not support the concept of set of macros, so I had to break it
for submission. The general documentation, as well as the sample
configure.in, is included in the AC_PROG_JAVA macro.
