The only confguration change from "normal" was adding the following config options to local.conf and rebuilding a fresh tmp/ tree and rpi image: JAVA = ",java" JAVA_arm = ",java" FORTRAN = ",fortran" The poky listing below shows gfortran (and a broken g77 symlink) but no gcj, so at this point I'm not sure if I'm missing some additional config settings for poky master, or if the additional language support is incomplete, or something else? So this is mostly informational(?) right now; today I'll try pulling on master again and rebuilding just to be sure. My current build config: Build Configuration: BB_VERSION = "1.21.0" BUILD_SYS = "x86_64-linux" NATIVELSBSTRING = "Ubuntu-12.04" TARGET_SYS = "arm-poky-linux-gnueabi" MACHINE = "raspberrypi" DISTRO = "poky" DISTRO_VERSION = "1.5+snapshot-20131213" TUNE_FEATURES = "armv6 vfp callconvention-hard arm1176jzfs no-thumb-interwork" TARGET_FPU = "vfp" meta meta-yocto meta-yocto-bsp = "master:257f83968caae834c03bc412eaf5afeadee6880e" meta-raspberrypi = "master:bcf257fd036890e5b26fa4f4874c4f072e9ec0a8" meta-erlang = "master:ca7c12f3427280a3800f78fa511637de3925d056" meta-oe meta-gnome meta-networking meta-filesystems meta-multimedia meta-efl meta-xfce = "master:20f352810d46daea9a20989b77f347fb8564ebf0" Poky toolchain: poky (master) $ find build-rpihf/tmp/sysroots/ -name libgfortran\* build-rpihf/tmp/sysroots/raspberrypi/pkgdata/runtime/libgfortran build-rpihf/tmp/sysroots/raspberrypi/pkgdata/runtime/libgfortran-dev build-rpihf/tmp/sysroots/raspberrypi/pkgdata/runtime/libgfortran-staticdev build-rpihf/tmp/sysroots/raspberrypi/pkgdata/runtime-reverse/libgfortran-staticdev build-rpihf/tmp/sysroots/raspberrypi/pkgdata/runtime-reverse/libgfortran-dev build-rpihf/tmp/sysroots/raspberrypi/pkgdata/runtime-reverse/libgfortran The Gentoo crossdev tool also can't build gcj support, at least not as part of the basic toolchain (didn't try the extra target). That said, it does build the full gfortran stuff, including libgfortran, which this one appears to be missing. gentoox86vm ~ # find /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi -name libgfortran\* /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.6.4/libgfortranbegin.la /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.6.4/libgfortran.spec /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.6.4/libgfortran.la /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.6.4/libgfortran.a /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.6.4/libgfortran.so /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.6.4/libgfortran.so.3.0.0 /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.6.4/libgfortranbegin.a /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.6.4/libgfortran.so.3 /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.5.4/libgfortranbegin.la /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.5.4/libgfortran.la /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.5.4/libgfortran.a /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.5.4/libgfortran.so /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.5.4/libgfortran.so.3.0.0 /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.5.4/libgfortranbegin.a /usr/lib/gcc/armv7a-hardfloat-linux-gnueabi/4.5.4/libgfortran.so.3 39486 1 stephen.arnold42 2013-12-19 04:48:46 +0000 The clean rebuild seems to have done it, although my local.conf now looks like this: JAVA = ",java" JAVA_arm = ",java" FORTRAN = ",fortran" FORTRAN_forcevariable = ",fortran" RUNTIMETARGET_append_pn-gcc-runtime = " libquadmath" After that I was able to build the libgfortran package; prior to the above I got the error about gcc needing to be built with fortran support.

As it mentioned there it is there as "best effort" and not an officially supported/tested code path. As such, bug reports like this aren't going to get much attention, we simply don't have the resources to cover fortran or java. For java you probably need to do something like: JAVA_forcevariable = ",java" but again, its not a tested codepath so who knows what may happen from there. Finally, the raspberrypi isn't an official Yocto Project BSP so as such a bug report for unsupported hardware and an unsupported toolchain components here in the bugzilla is really out of scope. 40058 4 richard.purdie 2014-01-28 12:01:56 +0000 No feedback on the bug. Fortran should work as indicated, java simply isn't supported.
