This patch makes Classpath use the AC_PROG_JAVAC macros from the autoconf archive, as Kaffe now does (see Dalibor's recent patches). Instead of detecting both ecj and javac, the build will now test for ecj, javac and gcj in that order, and use the first one. It tests the chosen compiler for 1.5 compatibility (a local extension) and we also retain the -J test. You can override the choice with JAVAC=<compiler of choice> and add options with JAVACFLAGS=<flags of choice>.ChangeLog: 2008-02-10 Andrew John Hughes <[EMAIL PROTECTED]> * NEWS: Mention javah and javac build changes. * configure.ac: Call AC_PROG_JAVAC and CLASSPATH_JAVAC_MEM_CHECK instead of CLASSPATH_FIND_JAVAC. * examples/Makefile.am: Simplify compiler choice to just use JAVAC. * lib/Makefile.am: Likewise, but with JAVAC_MEM_OPT too. * m4/ac_prog_javac.m4: New file. * m4/ac_prog_javac_works.m4: Likewise. * m4/acinclude.m4: (CLASSPATH_FIND_JAVAC): Removed.

Very cool. This should allow us to move to use straight automake java support at least for the examples, and tools, rather than using our own manual compiler flag assembly, source file listing and CVS directory purging scripts. Oh, and to rewrite the 1.5 checks in terms of AC_JAVAC_TRY_COMPILE. ;)
cheers, dalibor topic
