Bizarre project compilation issue

[Lurch]

Hey all - seeing really weird behavior trying to compile a plugin
On the latest git (last night) but saw this issue on previous builds too. I go Export>Compile project and run the exporter, get this far:

> Create C++ autogenerated files
> Create binary data files

And then it hangs forever, regardless of AU, VST etc being selected, regardless of project. Obviously that doesn't tell me much so I opened the Xcode project and compiled it there, it compiled straight away no issues - except the exported file is 32bit? Despite being on Apple Silicon and the flags all saying ARM64e, Support 32bit macOS flag in HISE is unticked. This means I can't test it, which obviously makes the whole thing a bit pointless.
This has happened on multiple builds of HISE, multiple commits, all my projects -

HISE 4.9.0 80bc4934
JUCE v6.1.3 (because JUCE 8 is currently not building in HISE)
Xcode Version 26.5 (17F42)
Apple clang version 21.0.0 (clang-2100.1.1.101)
Target: arm64-apple-darwin25.2.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Is there a way of getting verbose logs out of the HISE exporter so I can see or at least post what's happening?

@Lurch What happens if you use one of the export options instead of compile project?

[Lurch]

@David-Healey Should have included this, sorry - hangs forever here:

⚠️ Building targets in manual order is deprecated - check "Parallelize build for command-line builds" in the project editor, or set DISABLE_MANUAL_TARGET_ORDER_BUILD_WARNING in any of the targets in the current build to suppress this warning
note: Target dependency graph (3 targets)

[Lurch]

@Lurch Have now cleared the Xcode project, opened projucer and set the target arch to ARM64/ARM64e - export is still 32bit according to cubase?

@Lurch said in Bizarre project compilation issue:

What does it show in xcode

[Lurch]

@David-Healey I've fixed it - just incase anyone ever sees similar weirdness in future -

Open Terminal and:

xcode-select -p

That should return similar to:

/Applications/Xcode.app/Contents/Developer

If not, sort it with this:

sudo xcode-select --switch /Applications/Xcode.app
sudo xcodebuild -runFirstLaunch

Then reset dev tools:

sudo xcode-select --reset
sudo xcodebuild -license accept

Delete derived data and module cache:

rm -rf ~/Library/Developer/Xcode/DerivedData
rm -rf ~/Library/Developer/Xcode/ModuleCache.noindex

Double check clang if you've got clang errors:

clang --version
xcrun clang --version

If either of those hang, reinstall clang.

Reinstall commandlinetools:

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

Delete Xcode caches (bit severe but I think this is what sorted mine out):

rm -rf ~/Library/Caches/com.apple.dt.Xcode
rm -rf ~/Library/Preferences/com.apple.dt.Xcode.plist

Then reboot, open HISE and try your compile again - mine went straight through, no errors!
