Platform support for 'node' on PowerPC64LE

[sarveshtamba]

• I have been able to successfully deploy fabric8-launcher/launcher-operator on PowerPC64LE as mentioned in "Route Laucher not found on PPC64LE fabric8-launcher/launcher-operator#50 (comment)"

• Currently working on step to "Install the Launcher (via the installed operator)". Facing issues with the example launcher yaml which makes use of image: fabric8/launcher-backend:latest, which for now is available only for x86_64.

• I was facing the below failures on ppc64le while building fabric8/launcher-backend:

08:57:58.095 [main] INFO io.specto.hoverfly.junit.core.TempFileManager - Selecting the following binary based on the current operating system: hoverfly_linux_amd64

08:57:58.280 [Thread-2] INFO hoverfly - /root/fabric8/src/github.com/launcher-application/base/target/hoverfly.8425973283270400848/hoverfly_linux_amd64: /root/fabric8/src/github.com/launcher-application/base/target/hoverfly.8425973283270400848/hoverfly_linux_amd64: cannot execute binary file

• Built hoverfly for ppc64le successfully using https://github.com/SpectoLabs/hoverfly and then tried to use this locally built hoverfly installation in the fabric8/launcher-backend build. However I was not successful in that, so by-passed the test cases which made use of hoverfly using the command mvn clean install -DskipTests:-

• With this the build proceeded ahead, however it fails at the below step:-

• I also built Node 11.12.0 locally on ppc64le successfully to workaround the above issue , but I was not able to make use of this in fabric8/launcher-backend build.
  Any way I can force the build system to use the node version that I have built locally?

• Is node fully supported for PowerPC64LE and tested?

Any help towards this would be greatly appreciated.

node is supported/tested on ppc64le, but there are minimum gblic levels for the community binaries.

Which OS and distro are you working on. My guess is that it might be RH 7.

We've been working to improve the level of support by moving the community builds from ubuntu to centos7 (which has an earlier glibc). The latest 12.x release should run on RH 7.
The next 10.x relesae should as well. There are no plans for 8.x

I think there will also be images from RH and/or versions of Node.js available through the RH software collections but we'd have to confirm they are available for PPC

Have you tried installing libstdc++6 ? Its possible that's all you need to do to get node's official binaries to work.

Hi @mhdawson @sam-github, using node v12.11.0 as below worked fine and I was able to complete the maven build:

@sarveshtamba great to hear :)

[mhdawson]

@sarveshtamba any chance you could reach out to me through the email on my github id? I'd be interested in learning a bit about the work you are doing on the build scripts for PPCle

@mhdawson check your mail.
