py-pyside2: Could not resolve SDK --show-sdk-path for 'macosx'

[chrstphrchvz (Christopher Chavez)]

pyXX-pyside2 builds are failing on macOS 10.9-10.13 (10.14 unknown):

I'm not aware whether this issue existed prior to the recent pyside2 5.15.2 update. There appears to have been similar errors for other Qt ports but I do not know how it would be addressed for this port, or if an existing attempt to address it is ineffective.

(I do not use py-pyside2 on the affected macOS versions.)

might "use_xcode yes" if it's not already in there.

(I do not use py-pyside2 on the affected macOS versions.)

However, I do (my Portfile development machine runs 10.11). PySide2 support was recently added for the GUI viewer in the USD port, and I am currently in the process of updating its Portfile to this new version.

Looking on the builders, it looks like the cause of the pyside2 failures are different depending on the version of macOS. For example, the ​build for macOS 10.11 is failing due to CMake errors:

CMake Error at CMakeLists.txt:23 (find_package):
  Could not find a configuration file for package "Qt5" that is compatible
  with requested version "5.12".

  The following configuration files were considered but not accepted:

    /opt/local/libexec/qt5/lib/cmake/Qt5/Qt5Config.cmake, version: 5.11.3
    /opt/local/lib/cmake/Qt5/Qt5Config.cmake, version: 5.11.3

    raise RuntimeError(msg)
RuntimeError:

which seems to imply that there's an error determining which version of Qt5 should be used (possibly related to, or could be the same error as Chris pointed to above), or it could also imply that there's an error trying to build the shiboken2 dependency? On the other hand, the ​build for macOS 10.12 is apparently failing because the dependency qt511-qtwebengine is failing to install.

Also, one more thing: Is there some way for pyside2 to be used with pyside-tools? Looking at its Portfile, it looks like pyside-tools only depends on pyside. Perhaps there needs to be a new pyside2-tools package? If that's the case, then I can file a new, separate Trac ticket.

I think 10.11 ​caps out at qt 5.11 , so if this software requires qt5.12, you are Out Of Luck.

[chrstphrchvz (Christopher Chavez)]

Indeed pyside2 (​at least since 5.12.2) has required Qt 5.12. ​PR opened to reflect this in the port (leaving this port unavailable for older OSes rather than re-adding old versions).

In 8925eed5988a05f169bbf7356f44d373bc96ee43/macports-ports (master):

py-pyside2: requires at least Qt 5.12

Closes: #62135
