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