Error when I build py311-pyqt5 +webkit

[news24lor]

Hi

I have a new computer with M2 processor and I have installed last MacPorts and many packages without problems.

I have installed last QGIS3 and it works, but for working with many plugins it needs a new build of py311-pyqt5 +webkit. There is a note at the end of QGIS.

The normal packages "py311-pyqt5" works but with variant +webkit it is impossible to build. I have an error.

version:1
:debug:main Starting logging for py311-pyqt5 @5.15.9_0+webkit

Different architectures??

I have a complete log.

The error you mentioned in the ticket description makes no sense and does not appear in the log you attached. The error in the log you attached is:

Project ERROR: Could not resolve SDK Path for 'macosx13.3' using --show-sdk-path

There are a bunch of other tickets about that kind of error.

Hi Ryan

I've built the package in two ways:

1) from terminal I've the complete main.log
2) from jar GUI I only have the simple message of error above

The result is the same: the package is not built.
Only this variant is not built but it almost mandatory for QGIS3 (for many plugin)

I don't know if works fine for me:

>>> port installed | grep py311-pyqt5
py311-pyqt5 @5.15.9_0+webkit (active)
py311-pyqt5-sip @12.12.2_0 (active)
py311-pyqt5-webengine @5.15.6_1 (active)

on

macOS 14.0 23A344 x86_64
Xcode 15.0 15A240d

For reasons I don't fully understand yet I needed to install the md4c to get qt5-qtwebkit to build but after that the py311-pyqt5 +webkit build just fine. The error that is in your logfile has been seen many times in the past as Ryan points out; the last ticket about this port was 68073 but that seems to work now. In short, unless it's related to arm64 I don't know why it appears not to work for you; if it's related to arm64 there is nothing I can do about it as I don't have access to that hardware.

I don't know if the error is only in ARM processor with new Xcode 15.0.

I've put a problem with QGIS some week ago #67842 and after some changes the solution was a clean built of py311-pyqt5 +webkit

It worked but Xcode was the version 14.0 on ARM processor.

Now the same build doesn't work

I found the solution in the post #68073.
That solution was for macosx12.3 SDK and now for macosx13.3 SDK.

Basically the error is related to not identifying the maosx13.3 SDK in macOS 13.6 with Xcode version 15 on ARM processor.

I performed these steps:

I first checked for the presence of the SDK with

xcrun --sdk macosx13.3 --show-sdk-path

and I got the error xcodebuild: error: SDK "macosx13.3" cannot be located

I checked which SDK is present:

ls -l /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs
drwxr-xr-x 7 root wheel 224 31 Aug 21:12 MacOSX.sdk
lrwxr-xr-x 1 root wheel 10 18 Sep 20:28 MacOSX14.0.sdk -> MacOSX.sdk
lrwxr-xr-x 1 root wheel 10 18 Sep 20:28 MacOSX14.sdk -> MacOSX.sdk

The macosx13.3 SDK is not present.

I have created a link to the SDK needed for compilation:

sudo ln -s /Library/Developer/CommandLineTools/SDKs/MacOSX13.3.sdk /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.3.sdk

I re-checked which SDKs are present.

xcrun --sdk macosx13.3 --show-sdk-path
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.3.sdk

Now macosx13.3 SDK is present.

I will now redo the installation

sudo port install py311-pyqt5 +webkit

And finally everything works again!!!

It is a bit complex but it works. This variant is absolutely necessary inside QGIS to make many plugins work

Thanks again!

Replying to news24lor:

I found the solution in the post #68073.
That solution was for macosx12.3 SDK and now for macosx13.3 SDK.

Sym-linking an SDK is certainly not the correct solution or anything that should be recommended.

As I said above in comment:4; it works on x86_64 so it could be an arm64 issue; it that's the case I cannot help as I don't have access to that hardware. Additionally, webkit has been obsolete for quite some time now in Qt5 so I don't think there will be much help in getting this to work moving forward; instead, whatever plugins you want to use should likely migrate to a supported solution like "webengine".
