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?

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.

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).

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.
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.

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.
