The test looks for javac and finds the wrapper script installed by java-config, then tries to invoke it and fails because there's no real javac: /var/tmp/paludis/sys-devel-automake-1.10.1/work/automake-1.10.1/tests:/root/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/bin:/usr/x86_64-pc-linux-gnu/gcc-bin/4.1.2:/opt/blackdown-jdk-1.4.2.03/bin:/opt/blackdown-jdk-1.4.2.03/jre/bin:/usr/kde/4.0/sbin:/usr/kde/4.0/bin:/usr/kde/3.5/sbin:/usr/kde/3.5/bin:/usr/qt/3/bin:/opt/vmware/player/bin === Running test ./java.test ++ pwd /var/tmp/paludis/sys-devel-automake-1.10.1/work/automake-1.10.1/tests/testSubDir + set -e + cat + cat + aclocal-1.10 -Werror + autoconf + automake-1.10 --foreign -Werror -Wall + grep '^all[-a-z]*:.*classdist_java\.stamp' Makefile.in all-am: Makefile classdist_java.stamp + cat + cat ++ pwd + ./configure --prefix /var/tmp/paludis/sys-devel-automake-1.10.1/work/automake-1.10.1/tests/testSubDir checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /usr/bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking for javac... : configure: creating ./config.status config.status: creating Makefile + make distcheck { test ! -d java-1.0 || { find java-1.0 -type d ! -perm -200 -exec chmod u+w {} ';' && rm -fr java-1.0; }; } test -d java-1.0 || mkdir java-1.0 find java-1.0 -type d ! -perm -777 -exec chmod a+rwx {} \; -o \ ! -type d ! -perm -444 -links 1 -exec chmod a+r {} \; -o \ ! -type d ! -perm -400 -exec chmod a+r {} \; -o \ ! -type d ! -perm -444 -exec /bin/sh /var/tmp/paludis/sys-devel-automake-1.10.1/work/automake-1.10.1/tests/testSubDir/install-sh -c -m a+r {} {} \; \ || chmod -R a+r java-1.0 tardir=java-1.0 && /bin/sh /var/tmp/paludis/sys-devel-automake-1.10.1/work/automake-1.10.1/tests/testSubDir/missing --run tar chof - "$tardir" | GZIP=--best gzip -c >java-1.0.tar.gz { test ! -d java-1.0 || { find java-1.0 -type d ! -perm -200 -exec chmod u+w {} ';' && rm -fr java-1.0; }; } case 'java-1.0.tar.gz' in \ *.tar.gz*) \ GZIP=--best gunzip -c java-1.0.tar.gz | /bin/sh /var/tmp/paludis/sys-devel-automake-1.10.1/work/automake-1.10.1/tests/testSubDir/missing --run tar xf - ;;\ *.tar.bz2*) \ bunzip2 -c java-1.0.tar.bz2 | /bin/sh /var/tmp/paludis/sys-devel-automake-1.10.1/work/automake-1.10.1/tests/testSubDir/missing --run tar xf - ;;\ *.tar.lzma*) \ unlzma -c java-1.0.tar.lzma | /bin/sh /var/tmp/paludis/sys-devel-automake-1.10.1/work/automake-1.10.1/tests/testSubDir/missing --run tar xf - ;;\ *.tar.Z*) \ uncompress -c java-1.0.tar.Z | /bin/sh /var/tmp/paludis/sys-devel-automake-1.10.1/work/automake-1.10.1/tests/testSubDir/missing --run tar xf - ;;\ *.shar.gz*) \ GZIP=--best gunzip -c java-1.0.shar.gz | unshar ;;\ *.zip*) \ unzip java-1.0.zip ;;\ esac chmod -R a-w java-1.0; chmod a+w java-1.0 mkdir java-1.0/_build mkdir java-1.0/_inst chmod a-w java-1.0 dc_install_base=`CDPATH="${ZSH_VERSION+.}:" && cd java-1.0/_inst && pwd | sed -e 's,^[^:\\/]:[\\/],/,'` \ && dc_destdir="${TMPDIR-/tmp}/am-dc-$$/" \ && cd java-1.0/_build \ && ../configure --srcdir=.. --prefix="$dc_install_base" \ \ && make \ && make dvi \ && make check \ && make install \ && make installcheck \ && make uninstall \ && make distuninstallcheck_dir="$dc_install_base" \ distuninstallcheck \ && chmod -R a-w "$dc_install_base" \ && ({ \ (cd ../.. && umask 077 && mkdir "$dc_destdir") \ && make DESTDIR="$dc_destdir" install \ && make DESTDIR="$dc_destdir" uninstall \ && make DESTDIR="$dc_destdir" \ distuninstallcheck_dir="$dc_destdir" distuninstallcheck; \ } || { rm -rf "$dc_destdir"; exit 1; }) \ && rm -rf "$dc_destdir" \ && make dist \ && rm -rf java-1.0.tar.gz \ && make distcleancheck checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /usr/bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking for javac... : configure: creating ./config.status config.status: creating Makefile make[1]: Entering directory `/var/tmp/paludis/sys-devel-automake-1.10.1/work/automake-1.10.1/tests/testSubDir/java-1.0/_build' CLASSPATH=.:../.:$CLASSPATH javac -d . ../a.java ../b.java * javac is not available for sun-jre-bin-1.6 on x86_64 * IMPORTANT: some Java tools are not available on some VMs on some architectures make[1]: *** [classdist_java.stamp] Error 1 make[1]: Leaving directory `/var/tmp/paludis/sys-devel-automake-1.10.1/work/automake-1.10.1/tests/testSubDir/java-1.0/_build' make: *** [distcheck] Error 2
No idea what automake uses java for, but either it should be told not to test for it or use java eclasses and jdk dependency, which will set the env to a JDK even if active VM is JRE. Maybe there should be a java USE flag in which case the eclass is java-pkg-opt-2
it doesnt use java ... like a good library, it includes optional helper macros for other packages to use when running autotools if a java compiler is found, it'll be used to test its macros
