Hi all, There seems to be some problem with the autoconf macros in classpath-0.99 which was not present in 0.98. Looks like passing --disable-tools to configure also disables the javac detection code, resulting in the following error: === $ ./configure --disable-tools [...] checking whether javac supports -J... ./configure: line 24943: -J-Xmx768M: command not found no configure: error: conditional "GCJ_JAVAC" was never defined. Usually this means the macro was only invoked conditionally === Note that this didn't happen in 0.98 (just re-checked) so it is probably due to autoconf changes between 0.98 and 0.99 Quick workaround (not a proper fix) for systems using javac: $ JAVAC=javac GCJ_JAVAC_TRUE='\#' ./configure --disable-tools Best regards, Guillermo Rodriguez Garcia guille.rodriguez@xxxxxxxxx
