Description Andrew Cagney 2005-11-11 05:27:28 UTC

Need to re-vamp the build system so that it always uses GCJ, but also need to
ensure correctness of the code using ECJ.

A compromise is to make the ECJ pass part of make check :-/

	ajocksch	cagney: ah, I see where you're going. I've got my alternatives
pointing to sun right now, I'll change it to gcj and see if that fixes it
	cagney	ajocksch: yea, but sun or ibm? strace showed it sucking ibm's .so's
	ajocksch	cagney: yep, that fixes it
	ajocksch	cagney: sun
	cagney	really confused
	ajocksch	isn't much clearer
	cagney	waits for ajocksch to notice eclipse behaving wierd ;-0
	ajocksch	hehe, not yet, we'll see though
	cagney	ajocksch: check http://sourceware.org/bugzilla/show_bug.cgi?id=1852 ;
given this scrambled behavior perhaphs it should be implemented
	cagney	ajocksch: fyi, what happens is that the compiler looks at its Note from
IRC: turns out that on FC-5 gcj is a shells script that invokes the current
java-alternatives interpreter and, when it isn't gij, can't find things like
gnu.gij.RawData.  Below outlines solution:

        containing JVM's navel to find its own lint^Djar files
	ajocksch	cagney: yeah, that makes sense to me
	cagney	ajocksch: can you try something like: make 'JAVAC=gij -classpath
/usr/share/java/eclipse-ecj.jar org.eclipse.jdt.internal.compiler.batch.Main'
	cagney	ajocksch: antlr is run using something similar : :-P
	ajocksch	in frysk-sys? hang ong
	ajocksch	*on
	cagney	ongkay
	ajocksch	cagney: that works
	ajocksch	(with alternatives set to sun's jvm)
	cagney	ajocksch: thanks! I'll add it to the bug
