Need OpenJDK to be used on PowerPC for our products.

[Dipendu Ghosh]

Thank You David for the link. But that does not provide builds for Linux/PPC32 (single core e500v2).



I am trying to build the code locally following the steps available at https://openjdk.java.net/groups/build/doc/building.htmlbut but I am facing the below error while trying to cross compile.



Failure step:-

sh ./configure \

  --openjdk-target=aarch64-linux-gnu \

  --with-sysroot=~/sysroot-arm64



Error is as below:-

“configure: error: Could not find X11 libraries. You might be able to fix this by running 'sudo apt-get install libx11-dev libxext-dev libxrender-dev libxrandr-dev libxtst-dev libxt-dev'. configure exiting with result code 1”

The fix provided after the error is not solving the problem since the packages are already installed but somehow they are not being included in the sysroot.



Prior to the failure step I have executed the below command:-

sudo qemu-debootstrap \

--arch=arm64 \

--verbose \

--include=autoconf,fakeroot,symlinks,build-essential,libx11-dev,libxext-dev,libxrender-dev,libxrandr-dev,libxtst-dev,libxt-dev,libxss-dev,libxxf86vm-dev,libxkbfile-dev,libxv-dev,libxinerama-dev,libcups2-dev,libfontconfig1-dev,libasound2-dev,libfreetype6-dev,libjpeg-dev,libpng-dev,libffi-dev,jtreg

--resolve-deps \

buster \

~/sysroot-arm64 \

The AdoptOpenJDK project provides such builds:
