Hello, I just did git clean -dxf git pull that reported an error, saying that my local aclocal.m4 conflicts... I wonder why aclocal.m4 is part of the kawa source tree? rm -f aclocal.m4 git pull ./autogen.sh ./configure --prefix=/opt2 make fails [1] I'm posting this email, because I think it would be better if configure did report that javac was missing, not... (I had a disk crash, reinstalled ... discovering missing bits and pieces as I recompile my tools ... I see I have openjdk-10-jre-headless:amd64 installed, but (on debian buster) javac is in openjdk-10-jdk-headless:amd64, which was missing...
