Description

MacPorts 2.11.6 contains 4497293e70b1, the fix for #73160, which should make it significantly easier to build ports that depend on the Metal toolchain using Xcode 26.

It would be good to get the ports known to be affected by this problem built on the buildbot.

On the buildbot, assuming it’s updated to MacPorts 2.11.6, run:

% xcodebuild -downloadComponent MetalToolchain

While still using Xcode 26.0 or 26.0.1, additionally run:

% sudo --user=macports xcodebuild -showComponent MetalToolchain
% sudo rm -f "$(sudo --user=macports getconf DARWIN_USER_TEMP_DIR)/xcrun_db"

Then re-attempt builds for the following ports—links are to previous failing builds:

I pushed updates for openjdk21 21.0.10 and openjdk25 25.0.2 this month, which succeeded for me locally after installing the Metal toolchain, but these builds are failing on the macOS 26 buildbots, so it seems this issue is back.

openjdk21: https://build.macports.org/builders/ports-26_arm64-builder/builds/25096

checking for metal... [not found]
checking if metal can be run using xcrun... no
configure: error: XCode tool 'metal' neither found in path nor with xcrun
configure exiting with result code 1

openjdk25: https://build.macports.org/builders/ports-26_arm64-builder/builds/25097

checking for metal... [not found]
checking if metal can be run using xcrun... no
configure: A full XCode is required to build the JDK (not only command line tools)
configure: If you have XCode installed, you might need to reset the Xcode active developer directory
configure: using 'sudo xcode-select -r'
configure: error: XCode tool 'metal' neither found in path nor with xcrun
configure exiting with result code 1

So, it seems like the Metal toolchain on the buildbots is no longer getting found, while it was found before and it is found for me locally on macOS 26.2 with Xcode 26.2 with the Metal toolchain set up according to the instructions at TahoeProblems#MetaltoolchainisnolongerbundledinXcode.

I'm holding off on pushing updates for other OpenJDK versions for now, because I expect those builds will also fail to access the Metal toolchain on the buildbots.

On the bot, try removing the xcrun cache:

% sudo rm -f "$(sudo --user=macports getconf DARWIN_USER_TEMP_DIR)/xcrun_db"

and then retrying the build.

comment:5 Changed 6 weeks ago by ryandesign (Ryan Carsten Schmidt)

I already did that, since it's in the aforementioned instructions.

Can you show the output of these commands on that bot, running as the macports user?

xcodebuild -showComponent MetalToolchain
xcodebuild -find metal
xcrun_verbose=1 xcrun --find metal
xcrun_verbose=1 xcrun --sdk macosx --find metal
xcrun_verbose=1 xcrun --sdk macosx26.2 --find metal
xcrun metal --version
xcrun --sdk macosx metal --version
xcrun --sdk macosx26.2 metal --version
mount | grep MetalToolchain
ls -ldfT / /private /private/var /private/var/run /private/var/run/com.apple.security.cryptexd /private/var/run/com.apple.security.cryptexd/mnt /private/var/run/com.apple.security.cryptexd/mnt
ls -lT /private/var/run/com.apple.security.cryptexd/mnt

That should help figure out which step the problem is creeping in at.

(Yeah, it’s a lot, but I’m hoping to reduce the number of turnarounds.)

comment:7 in reply to: 6 Changed 5 weeks ago by breun (Nils Breunese)

Ryan, could you run the commands Mark posted on the macOS 26 arm64 buildbot? Hopefully this lets us spot what is causing the Metal toolchain to not get found, which is causing OpenJDK builds to fail on macOS 26.

Replying to breun:

Everything in comment 8 looks totally correct. I’d expect the build to succeed on that bot on the basis of what’s shown, assuming it’s running MacPorts 2.11.6 or later with the initgroups fix.

Can the build be retried? Then, only if it fails, we can repeat the investigation, in particular of the xcrun_verbose=1 xcrun --find commands?

Nils, note that the OpenJDK build has this quirk, where it finds metal by running xcrun -sdk macosx metal. The -sdk macosx circumvents the MacPorts-set SDKROOT, which may be undesirable, and results in xcrun using a different cache key than it would otherwise use. But JDK calling out -sdk macosx is why I asked for xcrun --sdk macosx --find metal above, and as you’ll see from Ryan’s response, xcrun was still able to resolve metal properly even with the SDK specified by that name. I don’t think that this is our problem, but you might still want to address it in the JDK ports regardless.

Sure; they'll show up at https://build.macports.org/builders/ports-26_arm64-watcher/builds/4679 tomorrow. (Until then, that URL will show "No such resource".)

It’s not necessarily uninstalled, just not mounted. Usually cryptexd would mount it on demand as needed. It won’t appear mounted after a reboot. xcodebuild -showComponent MetalToolchain should have caused it to be mounted, though.

If installed, /System/Library/AssetsV2/com_apple_MobileAsset_MetalToolchain/*/AssetData/Restore/*.dmg should show it.

022-20660-054.dmg is MetalToolchain 17C48. Does the bot have that?

The other thing I notice: the first difference between comment:8 and comment:15 is:

shell-init: error retrieving current directory: getcwd: cannot access parent directories: Permission denied

Does it help to cd to a “safe” (accessible to the macports user) directory immediately after sudo -u macports -s? (Perhaps this is a red herring, because the same error does appear later on in comment:8.)

It doesn't seem to make a difference.

Replying to ryandesign:

So weird!

If you install it again, can you do anything to monitor how long it sticks around, so we can maybe work out what’s causing it to be uninstalled?

comment:19 follow-ups: 20 21 Changed 3 weeks ago by axonde (Axonde ✦)

I'm experiencing a similar issue on my local machine (macOS 15.0, Xcode 16.0), Metal toolchain installed via MobileAsset, path:

/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-.../Metal.xctoolchain/usr/bin/metal

The configure script for openjdk25 fails with:

checking for metal... [not found]
checking if metal can be run using xcrun... no
configure: error: XCode tool 'metal' neither found in path nor with xcrun

However, xcrun itself locates the tool correctly:

% xcrun --sdk macosx --find metal
/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.3.519.0.4VzvkH/Metal.xctoolchain/usr/bin/metal
% xcrun --sdk macosx metal --version
Apple metal version 32023.850 (metalfe-32023.850.10)
...

It seems that during configuration, the check for metal either doesn't use xcrun correctly or the xcrun cache is not properly updated for the specific SDK used by the configure script.

Workaround that worked for me:

I created a symbolic link to metal in a directory already present in PATH (specifically /opt/local/bin):

sudo ln -s /var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-*/Metal.xctoolchain/usr/bin/metal /opt/local/bin/metal

After that, the configure step succeeded and the port built without issues.

This suggests that adding the ability to respect a METAL environment variable (like for CC, CXX) or improving the xcrun invocation in the configure script might help. Alternatively, ensuring that the xcrun cache is refreshed or that the path is added to PATH during configuration could also resolve it.

Hope this additional data helps in fixing the issue for both buildbots and end users.

Did you try the workaround documented on the wiki first?

What does the config.log say about why this failed?

See also the preceding comment from Nils.

Replying to breun and ryandesign:

Thanks for the pointers!

To answer your questions:

Did I try the wiki workaround first?

No, I didn't – I jumped straight to creating a symlink because xcrun already found the tool, and I assumed the configure script would respect that. I should have checked the wiki first.

What does config.log say?

I've now removed my symlink and followed the official workaround from TahoeProblems. After that, both openjdk21 and openjdk25 configured and built successfully without any errors. Since the build now works, the relevant config.log no longer shows the failure. If you'd like me to attach the original failing config.log (from before the fix) for reference, I can do that – just let me know.

So the wiki instructions are definitely correct and sufficient for a local setup like mine!
