Cross compiling Openjdk 8 for ARM, can't locate compiler (original) (raw)

Hi All,

As I was not able to compile OpenJDK 9 (there is disscussion in other mailing list). I tried to compile OpenJDK 8 precisely changeset 152-b02.

I configure this way:

./configure --with-jvm-interpreter=cpp
--with-jvm-variants=zero --enable-openjdk-only
--with-freetype-include=/linux/buildroot-openjdk8/output/host/usr/arm-buildroot-linux-gnueabi/sysroot/usr/include/freetype2
--with-freetype-lib=/linux/buildroot-openjdk8/output/host/usr/arm-buildroot-linux-gnueabi/sysroot/usr/lib
--with-freetype=/linux/buildroot-openjdk8/output/host/usr/arm-buildroot-linux-gnueabi/sysroot/usr/
--with-debug-level=release --openjdk-target=arm-buildroot-linux-gnueabi
--with-sys-root=/linux/buildroot-openjdk8/output/host/usr/arm-buildroot-linux-gnueabi/sysroot
--with-tools-dir=/linux/buildroot-openjdk8/output/host
--disable-freetype-bundling --enable-unlimited-crypto --disable-headful

BUILD_CXX=/linux/buildroot-openjdk8/output/host/usr/bin/arm-linux-gnueabi-g++
BUILD_CC=/linux/buildroot-openjdk8/output/host/usr/bin/arm-linux-gnueabi-gcc
BUILD_LD=~/linux/buildroot-openjdk8/output/host/usr/bin/arm-linux-gnueabi-gcc

The configure script seems to have some bug that it can't locate the compiler properly:

... checking for cl... /home/bruno/linux/buildroot-openjdk8/output/host/usr/bin/arm-linux-gnueabi-gcc configure: Resolving BUILD_CC (as /home/bruno/linux/buildroot-openjdk8/output/host/usr/bin/arm-linux-gnueabi-gcc) faile d, using /home/bruno/linux/buildroot-openjdk8/output/host/usr/bin/arm-linux-gnueabi-gcc directly. checking for cl... /home/bruno/linux/buildroot-openjdk8/output/host/usr/bin/arm-linux-gnueabi-g++ configure: Resolving BUILD_CXX (as /home/bruno/linux/buildroot-openjdk8/output/host/usr/bin/arm-linux-gnueabi-g++) fail ed, using /home/bruno/linux/buildroot-openjdk8/output/host/usr/bin/arm-linux-gnueabi-g++ directly. checking for ld... /home/bruno/linux/buildroot-openjdk8/output/host/usr/bin/arm-linux-gnueabi-gcc configure: Resolving BUILD_LD (as /home/bruno/linux/buildroot-openjdk8/output/host/usr/bin/arm-linux-gnueabi-gcc) faile d, using /home/bruno/linux/buildroot-openjdk8/output/host/usr/bin/arm-linux-gnueabi-gcc directly. checking for /home/bruno/linux/buildroot-openjdk8/output/host/usr/bin/arm-linux-gnueabi-gcc... no checking for /home/bruno/linux/buildroot-openjdk8/output/host/usr/bin/arm-linux-gnueabi-gcc... no configure: error: Could not find a C compiler.

Those files that it claims "no" do exist and they are indeed a GCC crosscompiler. The same parameters work for OpenJDK 9 (it does find the compiler).

How can I resolve this issue?

Thanks Bruno Kremel
