qt6 build failure on Rocky Linux 9.3 (TACC Stampede3)

[BenWibking]

I'm trying to build 3.4RC on TACC Stampede3.

This is a Rocky Linux 9.3 system. I have no CMake-related env vars defined in my shell. It builds fine on my laptop (at least without --xdmf), so I'm at a loss as to why it's failing here.

It fails when trying to build qt6:

$ ./build_visit --blosc2 --boxlib --hdf5 --adios2 --mesagl --llvm --xdmf --makeflags -j8

-- 

Qt is now configured for building. Just run 'cmake --build . --parallel'

Once everything is built, you must run 'cmake --install .'
Qt will be installed into '/tmp/bwibking/visit/src/tools/dev/scripts/third_party/qt/6.4.2/linux-x86_64_gcc-13.2'

To configure and build other Qt modules, you can use the following convenience script:
        /tmp/bwibking/visit/src/tools/dev/scripts/third_party/qt/6.4.2/linux-x86_64_gcc-13.2/bin/qt-configure-module

If reconfiguration fails for some reason, try removing 'CMakeCache.txt' from the build directory

Not sure about that error. I had success building Qt6 in a rocky-linux-9.3 container awhile back, but I was using gcc-11.4. Not sure if that makes a difference though.
In the output from Qt's config.summary:

Features used by QPA backends:
  evdev .................................. yes
  libinput ............................... no
  HiRes wheel support in libinput ........ no
  INTEGRITY HID .......................... no
  mtdev .................................. no
  tslib .................................. no
  xkbcommon .............................. no
  X11 specific:
    XLib ................................. yes
    XCB Xlib ............................. yes
    EGL on X11 ........................... no
    xkbcommon-x11 ........................ no
    xcb-sm ............................... no

The xkbcommon and xkbcommon-x11 entries should be yes in order for VisIt and Qt to play well together. This is likely a different issue than the ninja error mentioned in the logfile.

I can try a fresh container build, and see if I can get gcc-13 installed and see what happens.

The change we made to bv_ospray was to have its third-party dependencies pre-downloaded from our repo.
You can try commenting out this line in build_visit3_4_2, around line 15105:
download_file ${OSPRAY_LIBS_FILE}
which should then force ospray's build process to download what is needed from its own repo.
Blow away all the ospray files/dirs and try build_visit again.

I have never tried arm64, so if you can try the above 'fix' and let me know, that would be great.

[biagas]

BTW, thanks for the tip for the dockerfile specification of platform!

[BenWibking]

The OSPRay fix didn't work on arm64 for me. I still saw the same error. I started a new Docker build, but maybe there was something still cached from the previous build somehow?

On x86_64, it compiles VisIt but fails at the packaging step with:

The PreinstallOutput.log file didn't seem to show any errors. Let me know if there are any other logs I should check.

[biagas]

I would go into the visit3.4.2/build directory, and issue make and check for errors.
I have discovered compile errors related to not being able to find certain vtk headers.The errors are all in files that don't actually need the headers, so I've been modifying the files as I see the error. This is in a RockyLinux 9.3 instance in WSL, not a docker container. I had problems building Mili in my container.

What gcc version is being used in your container?

[BenWibking]

There are no errors reported when I run make. I then ran make package and it worked...very strange.

I've copied the build to Stampede3 and it appears to work, so I'll have to leave this mystery unresolved for now. Thanks for your help!
