Jim, I don't think zero builds are generally addressed on this list but ...

Hello, Trying to build OpenJDK 8 for armhf, ultimately to be hosted on a Raspberry Pi. I'm cross compiling from a Ubuntu 12.04 x86 Virtualbox image and am using gcc-4.7-linaro-rpi-gnueabihf for a toolchain. Configuration invocation looks as follows: $ bash configure --with-sys-root=/home/jimc/gcc-4.7-linaro-rpi-gnueabihf/ --target=arm-unknown-linux-gnueabihf --with-jvm-variants=zero --with-num-cores=2 The make fails like this: Compiling /home/jimc/openjdk8/hotspot/src/os/posix/vm/os_posix.cpp /home/jimc/openjdk8/hotspot/src/os/linux/vm/os_linux.cpp: In static member function 'static jint os::init_2()': /home/jimc/openjdk8/hotspot/src/os/linux/vm/os_linux.cpp:4853:42: error: 'workaround_expand_exec_shield_cs_limit' was not declared in this scope
You need to setup configure to do cross-compilation. I'm assuming you are building on an x86 box because that function is only defined on x86
#if defined(IA32) workaround_expand_exec_shield_cs_limit(); #endif I think --target=arm-unknown-linux-gnueabihf should be --openjdk-target=arm-unknown-linux-gnueabihf David
Might there a set of patches that are required to get this going further? Anything else I'm missing? Any pointer greatly appreciated, -- Jim C
