Making jffi-s390x-Linux.jar available

[gajju26]

Hi All,

JRuby is lacking support of s390x architecture to load jffi library. When raised the following issue
jruby/jruby#4632, I came to know I can build jffi on 390x platform and upload the jar file by creating a PR. My question is, I can build the master branch and make the jar file available but how will be latest released version taken care off by the community? Do in need to upload the jar file for every release or else by providing hardware community will take care of this thing? Is there any CI is in place for this?

I'm not a member of the JRuby project, but I would suggest creating not the jar, but an easy way for anyone to build a jar.

For instance, a docker image (or other kind of virtualized environment) that includes qemu and s390x libraries and a script to build the jar, or some instructions on how to get a s390x emulated environment up and going.

Just my 0.02 € :)

The native portion is intentionally small and does not need to be re-built for each release.

We have minimal CI only on Linux on x86_64, though I may set up an AArch64 build soon. Any help (even if temporary) maintaining CI on other platforms would be welcome :-)

I can try to set up CI on s390x architecture. But the jar generated for s390x will be picked up automatically under archive folder?

Hi Charles,

Meanwhile can I give you the jar file for s390x and then try to setup CI so that jar file will be available for each release.

@headius
I can try setting up CI on s390x can you give me some inputs about how to setup it. Also curious to know about CI activity, in the backend what is being used Jenkins or Travis?

@gajju26 Sorry this fell through the cracks. We have CI on Travis, which is simply x64 Linux. We would love to have you build an s390x binary for us! I don't know anything about that platform though. Are you able to try building jffi?

@headius I know this thread is a little dated but I would love to help out with setting up s390x CI build. I'll make sure to comment over on #69, as it seems everyone is discussing cross-compiling over there.
