Failed to configure qt5-qtbase

[pcmock]

OS 11.3.1 xcode 12.5 The qt5-qtbase install complains about the macOS 11 SDK is not installed even thought it is installed.

The problem seems to be that my OS is 11.3.1, and the SDK is macosx11.3 instead of macosx11.3.1. Is there a workaround?

xcrun --sdk macosx11.3 --show-sdk-path      
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.3.sdk

xcrun --sdk macosx11.3.1 --show-sdk-path
xcodebuild: error: SDK "macosx11.3.1" cannot be located.
xcodebuild: error: SDK "macosx11.3.1" cannot be located.
xcrun: error: unable to lookup item 'Path' in SDK 'macosx11.3.1'

[pcmock]

The initial SDK warning originates from line 3402 in:

libexec/macports/lib/port1.0/portutil.tcl

The SDK error originates from line 233 in:

var/macports/build/_Volumes_ZivaDrive_MacPorts_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_aqua_qt5/qt5-qtbase/work/qtbase-everywhere-src-5.15.2/configure

I tried replacing line 233 with:

sdk="macox11.3"

that seemed to help, but it was not sufficient.

[ryandesign (Ryan Carsten Schmidt)]

MacPorts has never attempted to use any x.y.z version for an SDK; no such SDK has ever existed. It's always been only an x.y version.

If you have not done so, install the command line tools using xcode-select --install as the message suggested.

[jmroot (Joshua Root)]

Replying to ryandesign:

If you have not done so, install the command line tools using xcode-select --install as the message suggested.

If this is happening with other ports and not just qt5, that may be it. But qt5 does change the SDK options in unusual ways.

[pcmock]

I had already tried this.

xcode-select --install
xcode-select: error: command line tools are already installed, use "Software Update" to install updates

Also xcrun finds the SDK as shown above, but it fails at line 233 in:

var/macports/build/_Volumes_ZivaDrive_MacPorts_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_aqua_qt5/qt5-qtbase/work/qtbase-everywhere-src-5.15.2/configure

I have 26379 ports installed successfully. Please note that the qt5_qtbase installer cannot find the SDK in line 3402 of:

libexec/macports/lib/port1.0/portutil.tcl

Replying to pcmock:

I have 26379 ports installed successfully.

I just have to stop for a moment here and say Holey Canoley.

That must be some kind of record.

[pcmock]

No. I'm sorry about my ignorance. I have 470 installed ports.

port list | wc -l

counts all available ports.

[pcmock]

Is there an environment variable that would help the qt5-qtbase installer find the SDK?

[pcmock]

I uninstalled and reinstalled Xcode, MacPorts and all ports, and qt5-qtbase still will not install. The symptoms are the same, and it fails in configure. If I modify line 233 in configure as describe earlier, configure runs a lot longer, but it still fails in configure. I'm attaching that main.log file as qtb2.log.

[kencu (Ken)]

configure wants an sdk that matches macosx11, but it doesn't exist.

what does exist, on your system now, is macosx and macosx11.3.

This appears to be internal to qt5, unless some PG or Portfile command is messing with it.

Not sure yet -- I don't think many people have built qt5 since the Xcode upgrade, as everyone else installs into /opt/local and so picks up the prebuilt binaries from the buildbot.

Proper fix is to first scour the Portfiles and PortGroups and patchfiles and see if we're doing anything to this, and then if not, patch configure to look for something that actually exists (it's a moving target as Apple changes things).

For you, right now -- I would make a symlink myself so that macosx11 is found, built qt5, and destroy the symlink when it's built. But no MacPorts committer and/or admin should make such a heathen recommendation, so you're stuck until Marcus or somebody like Marcus (me, etc) get around to trying to rebuild qt5-base again against the newest Xcode on BigSur, and fix the build, hopefully without breaking all the previous systems in the process.

qt5 is a bit of a beast, and challenges all build systems, and patience, to the limit.

[pcmock]

Thank you, but I'm doing something wrong. Is this what you meant?:

sh-3.2# pwd
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs
sh-3.2# ls -l
total 0
drwxr-xr-x  5 root  wheel  160 Mar 16 07:03 DriverKit20.4.sdk
drwxr-xr-x  7 root  wheel  224 Mar 16 07:03 MacOSX.sdk
lrwxr-xr-x  1 root  wheel   10 May 21 09:28 MacOSX11.sdk -> MacOSX.sdk

I think this is problem:

% xcrun --sdk macosx11 --show-sdk-path 
xcodebuild: error: SDK "macosx11" cannot be located.
xcodebuild: error: SDK "macosx11" cannot be located.
xcrun: error: unable to lookup item 'Path' in SDK 'macosx11'

but I don't know how to fix it.

[pcmock]

xcrun works with:

% xcrun --sdk macosx11.3 --show-sdk-path 
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.sdk

What else needs to be changed?

[gcs-github (Guillaume Ceccarelli)]

I ran into the same problem, and ended up working around it by changing qt's mkspec file @ qtbase-everywhere-src-5.15.2/mkspecs/common/macx.conf so that QMAKE_MAC_SDK = macosx11.3 (I also set QT_MAC_SDK_VERSION_MAX to 11.3 for good measure, but I don't think that had much of an impact).

Could a suggestion for a fix be to dynamically patch the mkspecs file or otherwise override it so that QMAKE_MAC_SDK is set to macosx{{major}}.{{minor}} when building?

[pcmock]

That worked! I had to run it twice. I don't know why it failed the first time. I also changed both macx.conf files:

qtbase-everywhere-src-5.15.2/mkspecs/common/macx.conf
qtbase-everywhere-src-5.15.2/mkspecs-save/common/macx.conf

Thank you!

Should be addressed by ​https://github.com/macports/macports-ports/commit/bd6b98885444240223213eabfc87bc18e1919ed5

[mascguy (Christopher Nielsen)]

@cjones, per your commit comment, is this now resolved then?

​https://github.com/macports/macports-ports/commit/bd6b98885444240223213eabfc87bc18e1919ed5#commitcomment-59292909

[cjones051073 (Chris Jones)]

I believe so yes. qt5-qtbase (and other qt ports) have built fine for me with this on macOS12 (intel).

[kencu (Ken)]

let's keep these all in one ticket, as they all seem to be the same problem with xcrun.
