I am confused. Once I added the call to 'R CMD javareconf' to be done before 'R CMD INSTALL ...your tarball...' happens, it _builds_ but then failed on a subsequent command that is not from me. I could patch that.

Also I'm surprised to the the odd paths "/usr/lib/jvm/default-java/" since at least in my installations I see the actual JVM being used - but then I don't know how your package (or Debian?) abstracts the Java version mess. | > | > | > | > | > | > This was vanilla 'openjdk-9-jdk' and nothing else. | > | > | > | > | > | > Could I / should invoke 'R CMD javareconf' ? | > | > | > | > | > | > Dirk | > | > | > | > | > | > | Cheers, | > | > | > | Simon | > | > | > | | > | > | > | | > | > | > | > On Oct 17, 2017, at 10:24 PM, Dirk Eddelbuettel <e...@debian.org> wrote: | > | > | > | > | > | > | > | > | > | > | > | > Simon, | > | > | > | > | > | > | > | > With your new rJava_0.9-9 I tried this against Debian's openjdk-9-jdk -- but | > | > | > | > with R 3.4.2 as built against openjdk-7 -- and it still fails: | > | > | > | > | > | > | > | > checking whether setjmp.h is POSIX.1 compatible... yes | > | > | > | > checking whether sigsetjmp is declared... yes | > | > | > | > checking whether siglongjmp is declared... yes | > | > | > | > checking Java support in R... present: | > | > | > | > interpreter : '/usr/lib/jvm/default-java/jre/bin/java' | > | > | > | > archiver : '/usr/lib/jvm/default-java/bin/jar' | > | > | > | > compiler : '/usr/lib/jvm/default-java/bin/javac' | > | > | > | > header prep.: '/usr/lib/jvm/default-java/bin/javah' | > | > | > | > cpp flags : '-I/usr/lib/jvm/default-java/include -I/usr/lib/jvm/default-java/include/linux' | > | > | > | > java libs : '-L/usr/lib/jvm/default-java/jre/lib/amd64/server -ljvm' | > | > | > | > checking whether Java run-time works... ./configure: line 3736: /usr/lib/jvm/default-java/jre/bin/java: No such file or directory | > | > | > | > no | > | > | > | > configure: error: Java interpreter '/usr/lib/jvm/default-java/jre/bin/java' does not work | > | > | > | > ERROR: configuration failed for package 'rJava' | > | > | > | > * removing '/build/rjava-0.9-9/debian/r-cran-rjava/usr/lib/R/site-library/rJava' | > | > | > | > /usr/share/R/debian/r-cran.mk:101: recipe for target 'R_any_arch' failed | > | > | > | > make: *** [R_any_arch] Error 1 | > | > | > | > dpkg-buildpackage: error: fakeroot debian/rules binary gave error exit status 2 | > | > | > | > | > | > | > | > | > | > | > | > Any ideas?
