Hi, I've now lost two days by trying out all the versions I could find at: http://www.perzl.org/aix/index.php?n=Main.LibXrandr http://www.bullfreeware.com/affichage.php?id=3351 http://www.oss4aix.org/download/RPMS/libXrandr The problem with all of them is that they depend on libXrender.so.1. That version is provided by the corresponding Xrender packages from that sites BUT the default AIX version of libXrender.a only contains libXrender.so.0. OpenJDK's libawt_xawt.so is linked against the system libXrender.so.0 an I don't think it would be good to change that. So that means we finally can't load libXrandr at runtime anyway. Sorry to say, but AIX X11 really seems to be terribly outdated and I don't see any sense in fixing this. Moreover, all the code in java.desktop/unix/native/libawt_xawt/awt/awt_GraphicsEnv.c which uses "dlopen()" is broken on AIX anyway (and it always has been, even in IBM's J9) because on AIX we would have to use dlopen with a shared library name PLUS the corresponding member name PLUS the RTLD_MEMBER flag. E.g.: dlopen("libXrandr.a(libXrandr.so.2)", RTLD_MEMBER | RTLD_LAZY | RTLD_LOCAL); As people don't really seem to have cared until now, I'll propose a minimal fix for "8213944: Fix AIX build after the removal of Xrandr.h and add a configure check for it" [1] which simply #ifdefs out all this broken functionality on AIX (see review thread at [2]) With best regards, Volker [1] https://bugs.openjdk.java.net/browse/JDK-8213944 [2] http://mail.openjdk.java.net/pipermail/2d-dev/2018-November/009636.html On Fri, Nov 16, 2018 at 7:05 PM Volker Simonis <volker.simonis@gmail.com> wrote:
Hi Ichiroh,
thanks a lot for the pointers.
Up to now, I tried to only depend on "official" IBM packages (i.e. original AIX packages or packages from the "AIX Toolbox for Linux Applications" [1]) for both, the build and at runtime. I'm not sure how "reliable" the packages from perzl.org are, but in general I want to avoid unverified dependencies.
That said, I don't know Xrandr makes any sense on AIX at all. As far as I can see, it hasn't worked until now anyway. Or can anyone report any successful usage of Xrandr on AIX with these packages?
Thank you and best regards, Volker

Hello Volker.
I'm not sure, you want to know following information.
User can download libXrandr for AIX via Perzl.org AIX Open Source Packages site. [1][2]
I have not used this library, so I don't know the detail.
I checked the contents of libXrandr-devel-1.5.1-1.aix5.1.ppc.rpm [3]
$ rpm -qpl libXrandr-devel-1.5.1-1.aix5.1.ppc.rpm /opt/freeware/include/X11/extensions/Xrandr.h /opt/freeware/lib/libXrandr.la /opt/freeware/lib/pkgconfig/xrandr.pc /opt/freeware/man/man3/XRRConfigCurrentConfiguration.3 /opt/freeware/man/man3/XRRConfigCurrentRate.3 /opt/freeware/man/man3/XRRConfigRates.3 /opt/freeware/man/man3/XRRConfigRotations.3 /opt/freeware/man/man3/XRRConfigSizes.3 /opt/freeware/man/man3/XRRConfigTimes.3 /opt/freeware/man/man3/XRRFreeScreenConfigInfo.3 /opt/freeware/man/man3/XRRGetScreenInfo.3 /opt/freeware/man/man3/XRRQueryExtension.3 /opt/freeware/man/man3/XRRQueryVersion.3 /opt/freeware/man/man3/XRRRootToScreen.3 /opt/freeware/man/man3/XRRSelectInput.3 /opt/freeware/man/man3/XRRSetScreenConfig.3 /opt/freeware/man/man3/XRRSetScreenConfigAndRate.3 /opt/freeware/man/man3/Xrandr.3 /usr/lib/libXrandr.la $

Hi AIX experts,
a recent change ("8210863: Remove Xrandr include files from JDK sources" [1]) has removed the Xrander header files which were previously checked in in the OpenJDK sources, from there. This means that the build now requires the platform version of these header files:
X11/extensions/Xrandr.h X11/extensions/randr.h
To the best of my knowledge, AIX does not support the Xrandr extension and I couldn't find the corresponding header files any where (even not in the "AIX Toolbox for Linux Applications" [2]).
I've therefor prepared a change which fixes these issues on AIX (see: http://mail.openjdk.java.net/pipermail/2d-dev/2018-November/009636.html).
However, before pushing this fix, I'd like to get a confirmation if Xrandr is indeed not supported and not available on AIX. If it is, please point me to a place where I can get a package with the corresponding header files.
Thank you and best regards, Volker
