| 3 | dnl AC_PROG_JAVAC tests an existing Java compiler. It uses the
|
|---|
| 4 | dnl environment variable JAVAC then tests in sequence various common
|
|---|
| 5 | dnl Java compilers. For political reasons, it starts with the free
|
|---|
| 6 | dnl ones.

| 13 | dnl - at the configure level, setenv JAVAC

| 15 | dnl You can use the JAVAC variable in your Makefile.in, with @JAVAC@.

| 20 | dnl TODO: allow to exclude compilers (rationale: most Java programs
|

| 21 | dnl cannot compile with some compilers like guavac).

| 23 | dnl Note: This is part of the set of autoconf M4 macros for Java
|
|---|
| 24 | dnl programs. It is VERY IMPORTANT that you download the whole set,
|
|---|
| 25 | dnl some macros depend on other. Unfortunately, the autoconf archive
|
|---|
| 26 | dnl does not support the concept of set of macros, so I had to break it
|
|---|
| 27 | dnl for submission. The general documentation, as well as the sample
|

| 28 | dnl configure.in, is included in the AC_PROG_JAVA macro.
