| 5 | # SYNOPSIS | |
| 6 | # | |
| 7 | # AX_PROG_JAVAC | |
| 8 | # | |
| 9 | # DESCRIPTION | |
| 10 | # | |
| 11 | # AX_PROG_JAVAC tests an existing Java compiler. It uses the environment | |
| 12 | # variable JAVAC then tests in sequence various common Java compilers. For | |
| 13 | # political reasons, it starts with the free ones. | |
| 14 | # | |
| 15 | # If you want to force a specific compiler: | |
| 16 | # | |
| 17 | # - at the configure.in level, set JAVAC=yourcompiler before calling | |
| 18 | # AX_PROG_JAVAC | |
| 19 | # | |
| 20 | # - at the configure level, setenv JAVAC | |
| 21 | # | |
| 22 | # You can use the JAVAC variable in your Makefile.in, with @JAVAC@. | |
| 23 | # | |
| 24 | # *Warning*: its success or failure can depend on a proper setting of the | |
| 25 | # CLASSPATH env. variable. | |
| 26 | # | |
| 27 | # TODO: allow to exclude compilers (rationale: most Java programs cannot | |
| 28 | # compile with some compilers like guavac). | |
| 29 | # | |
| 30 | # Note: This is part of the set of autoconf M4 macros for Java programs. | |
| 31 | # It is VERY IMPORTANT that you download the whole set, some macros depend | |
| 32 | # on other. Unfortunately, the autoconf archive does not support the | |
| 33 | # concept of set of macros, so I had to break it for submission. The | |
| 34 | # general documentation, as well as the sample configure.in, is included | |
| 35 | # in the AX_PROG_JAVA macro. | |
