py27-pyqt4 not able to 'findqaxobject.h' in cfgtest_QAxContainer.cpp:1:10

[MountainLogic (Scott Elliott)]

I am attempting to build GnuRadio that requires py27-pyqt4 in OSX 10.13.5. When building py27-pyqt4 I receive the following error:

QAxContainer -framework QtGui -F/opt/local/Library/Frameworks -framework QtCore -framework QtCore
:info:configure cfgtest_QAxContainer.cpp:1:10: fatal error: 'qaxobject.h' file not found
:info:configure #include <qaxError: Unable to create the C++ code.
:info:configure object.h>
:info:configure          ^~~~~~~~~~~~~
:info:configure 1 error generated.

With version info

:debug:sysinfo macOS 10.13 (darwin/17.6.0) arch i386
:debug:sysinfo MacPorts 2.5.2
:debug:sysinfo Xcode 9.4.1
:debug:sysinfo SDK 10.13
:debug:sysinfo MACOSX_DEPLOYMENT_TARGET: 10.13

This seems odd as cfgtest_QAxContainer.cpp appears to refer to a Windows active X technology. See ​https://stackoverflow.com/questions/22672388/multiple-undefined-references-when-trying-to-build-pyqt4-from-the-sources. I assume that there might be a make define missing to build the Mac version.

I've attempted to clean py27-pyqt4, gnuradio etc with no luck (not installed). I had the working with a previous in Sierra with a previous version of gnu radio. QT4 is old and crufty, but the current gnu radio still requires it until its next major release.

py27-pyqt4-main.log

The file is there:

$ locate qaxobject.h
/opt/local/libexec/qt4/include/Qt/qaxobject.h
/opt/local/libexec/qt4/share/doc/html/qaxobject.html

but your build is not finding it, for some reason...

The issue is with SIP 4.19.10. I've got a query in to the lead developer.

[michaelld (Michael Dickens)]

You'll see the same issue if you try to configure py*-qsci*-*, py*-PyQt4, and I'd guess py*-PyQt5 and some others.

[michaelld (Michael Dickens)]

Can folks here try the attached patch that reverts py*-sip to 4.19.8? Reverting in this manner seems to do the trick for me; wanted to verify with others before committing.

[michaelld (Michael Dickens)]

Meh ... this change works for me as I hoped it would. I'm going to commit it as is & see how the dice roll LOL.

In d994dc3010dc47777db3765f7b68e6a5425b639d/macports-ports (master):

py*-sip: revert to 4.19.8

... due to issues building py*-Qsci-qt* and PyQt*.

should address: #56746

[michaelld (Michael Dickens)]

Can someone please report back whether this change worked or not?

[kencu (Ken)]

works to build py27-pyqt4.

Great thx. Closing.
