Hi Michael,
Götz was a bit faster
Let me add that I had only provided hints to help Tyler getting 11.0.16 buildable on AIX after the harfbuzz library upgrade.
That is only possible with xlclang frontend of xlc 16 (or later).
And yes, you’re right that this requires https://www.ibm.com/support/pages/ibm-xl-cc-runtime-aix-161<https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ibm.com%2Fsupport%2Fpages%2Fibm-xl-cc-runtime-aix-161&data=05%7C01%7Cgoetz.lindenmaier%40sap.com%7Cc7deb7ed598b4586bf0508da2826cc24%7C42f7676cf455423c82f6dc2d99791af7%7C0%7C0%7C637866444355553149%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=6rrh95fPXHf%2Fao6EkfRVZ%2FlK6hl2Sy1GmX6Q%2F5Ruo6Y%3D&reserved=0>
as it already required by later JDK releases.
I suggest emphasizing this on the Adptium download page or wherever it is appropriate to publish.
Do you need this information anywhere where you don’t have access?
Building on AIX 7.1 TL4 should be fine. Even though anything below TL5 is already post EoSPS:
https://www.ibm.com/support/pages/aix-support-lifecycle-information
Note that there is an alternative proposal to keep 11.0.16 buildable with old xlc, but it includes old harfbuzz. I wouldn’t recommend sticking with old and unmaintained libraries.
https://github.com/openjdk/jdk11u-dev/pull/991
I think requiring the runtime installed is the better choice. Do you agree?
Best regards,
Martin

Hi Michael,
> Question: is this infor only from SAP support perspective?
Are you asking about what is listed on https://wiki.openjdk.java.net/display/Build/Supported+Build+Platforms ?
SAP no more builds or tests the AIX port. Before we would fix
all issues coming up with the tool chain listed on that page.
But we terminated the active support of AIX. (Similar linuxppc64 be
and linuxs390x.)
IBM took over the responsibility to support AIX with 11.0.13, 17.0.1 and
18+.
As Martin of SAP still leads the ppc/aix porting project and we have access to
the wiki page, we will update it on IBM’s demand.
To how “Other JDK 11 build platforms” is to read as of today:
* AIX ppc64 was supported by SAP until 11.0.12.
* AIX ppc64 is currently supported by IBM.
* IBM builds 11.0.15 on AIX 7.1 with xlc 12.1
* IBM builds 11.0.16 on AIX 7.1 with xlc 16.1
Best regards,
Goetz.

Question: is this infor only from SAP support perspective?
re: supported build platforms and AIX. Adoptium is building on AIX 7.1 TL4 (SP4), generally with xlc-13.
After the release this week, iirc, for java11, due to a change in a component iirc, xlc16 will be used instead (or is is xlC, xlC is installed in any case) – but still from AIX 7.1 TL4.
Iirc: xl[cC]16 requires AIX 7.1 TL3 and later (maybe TL4).
The more important bit is the RTE users will need to download for xlC16: https://www.ibm.com/support/pages/ibm-xl-cc-runtime-aix-161<https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ibm.com%2Fsupport%2Fpages%2Fibm-xl-cc-runtime-aix-161&data=05%7C01%7Cgoetz.lindenmaier%40sap.com%7Cc7deb7ed598b4586bf0508da2826cc24%7C42f7676cf455423c82f6dc2d99791af7%7C0%7C0%7C637866444355553149%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=6rrh95fPXHf%2Fao6EkfRVZ%2FlK6hl2Sy1GmX6Q%2F5Ruo6Y%3D&reserved=0>
Forget if you have that bit on the supported platform page – but it is really needed.
FYI: I do a lot of the system admin for (Adoptium) AIX at OSU.

Thanks all for your comments and feedback.
Good point Martin. Those required backports will be my focus for the next little while.
Matthias, it seems you are the one with access to the Supported Build Platforms wiki (https://wiki.openjdk.java.net/display/Build/Supported+Build+Platforms) please update the xlc version number for jdk11 to 16.1 when you have a chance. I will follow up with changes to the notes section as well. Much appreciated :-)

Are the xlc16 – related changes already all in jdk11u-dev now ?
>probably we should change the minimum requirement of jdk12 too then.
JDK12 does not have the harfbuzz 2.8.0 backport so probably no need to change theSupported Builds document.

cc build-dev.
Hi Tyler, makes sense to me. Wrt the documentation, probably we should change the minimum requirement of jdk12 too then.

Hi all,
In regards to the new Harfbuzz version bump (and the work done to prepare for it). And of special importance now that
the Adoptium build of jdk11u-dev is
failing [https://ci.adoptopenjdk.net/job/AIX-jdk11-dev-build/17/execution/node/51/log/<https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fci.adoptopenjdk.net%2Fjob%2FAIX-jdk11-dev-build%2F17%2Fexecution%2Fnode%2F51%2Flog%2F&data=05%7C01%7Cgoetz.lindenmaier%40sap.com%7Cc7deb7ed598b4586bf0508da2826cc24%7C42f7676cf455423c82f6dc2d99791af7%7C0%7C0%7C637866444355553149%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=Ftw6Y6UKnfQM8vjngDdSZ%2F2CXFlKUsBKkUqIb49kSOk%3D&reserved=0>], I wanted to suggest a course of
action to the AIX-folks here to get suggestions before I make any changes.
Early this week, I spent some time looking into this issue. My assessment is that AIX builds for jdk versions 11 and
greater will need the at least xlc version 16.1 to support the Harfbuzz change. This is because full support for C++11
with xlc did not arrive on AIX until that version (little-endian support was complete in 13.1).
For reference:
"IBM XL C++ for AIX
- Core language support status: C++11 partial in 13.1.3 and 16.1.0 (xlC frontend), complete in 16.1.0 (xlclang
frontend)" [source: https://en.cppreference.com/w/cpp/compiler_support<https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fen.cppreference.com%2Fw%2Fcpp%2Fcompiler_support&data=05%7C01%7Cgoetz.lindenmaier%40sap.com%7Cc7deb7ed598b4586bf0508da2826cc24%7C42f7676cf455423c82f6dc2d99791af7%7C0%7C0%7C637866444355553149%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=45WRV%2BkXXhnDBLWE2k049V%2F8uE4DCn21J5qcGpX9kGw%3D&reserved=0> ]
My expected course of action is as follows:
- Bump the minimum requirements in our Supported Builds document
[https://wiki.openjdk.java.net/display/Build/Supported+Build+Platforms]
- Open an issue with the Adoptium group to change their build for jdk11 and above to use the version 16 compiler.
As I am still relatively new to AIX and OpenJDK development, so I value any suggestions for improvements, omissions you
may have noticed, or generally other comments the team here may have.
