ARM M1 issue Incompatible architecture: Cannot find arm64e in fat binary

[bezromval]

The installer report is:

Error Domain=KMErrorDomain Code=3 "Error occurred unloading extensions: Missing extension with identifier com.emu.driver.EMUUSBAudio : Incompatible architecture: Cannot find arm64e in fat binary

@bezromval thanks for reporting. Yes I was expecting it.

Your report "end of era ..." introduction is not so to the point and a bit negative so I removed that.

I already tried to recompile the code but it does not seem to generate the ARM binary and spits errors where the code wes compiling in the previous XCode And I don't have access to any ARM machine so even if it would compile I would be unable to test this

In short it may take some time before I can fix this

------- notes for myself

Main error message I get from the compiler:

TARGET_OS_OSX not defined
cdefs.h
In file included from ...EMUUSUAudio_info.c

Actually I'm i porting xmach/mach_types.h there.
Strange, error comes not from my code but from a standard library.

[Wouter1]

XCode says the file that causes the error is EMUUSBAudio_info.c
Ny project does not have such a file?
It does have a file EMUUSBAudio-info.plist. Is this something odd being generated wrong?

I also can NOT edit this 'file'. The filename is also in italics, not clear what's going on

The error says something like "in file included from /Users/wouter/Library/Developer/Xcode/DerivedData/EMUUSBAudio-fjaszixeghwepcdugnckcrbgnuhj/Build/Intermediates.noindex/EMUISBAudio.build/Debug/........

That's not where I put my source files either

[Wouter1]

Similar error to here
catchorg/Catch2#2139
But no solution reported there

[Wouter1]

https://stackoverflow.com/questions/12132933/preprocessor-macro-for-os-x-targets

gives more details but it's quite confusing

[Wouter1]

INFOPLIST_PREPROCESS=YES is in the project settings (project.pbxproj).
I think this creates the above mentioned file that includes cdef.h

If I uncheck that, the error remains because cdefs.h is still imported through

EMU-driver/USH.h -> IOKit/usb/StandardUSB.h -> IOKit->IOTypes.h -> IOKit/system.h -> sys/cdefs.h

[Wouter1]

If I put

#include <TargetConditionals.h>

right before the #include<IOKit/usb/StandardUSB.h>

then I get

IOKit/usb/IOUSBLog.h file not found.

Maybe this is a step in the right direction

[Wouter1]

After just removing that import, I'm back to the TERGET_OS_OSX not defined

But now through the import chain

EMUUSBAudio_info.c -> mach/mach_types.h->stdint.h -> machine/types.h -> i396/types.h -> sys/cdefs.h

[Wouter1]

Again that is NOT my file.
I have turned off the preprocess info.plist file.
Also the "Create Info.plist section in binary" is off.

[Wouter1]

This Derived Data seems wrong.
Maybe I can find more about derivedData

might help

[Wouter1]

Is this an XCode configuration issue?

https://developer.apple.com/library/archive/documentation/DeveloperTools/Conceptual/cross_development/Configuring/configuring.html

[Wouter1]

Well that first line there is already confusing. " you install Xcode, the installer creates a /Developer/SDKs directory"

I HAVE Xcode installed. But I don't have /Developer.

EDIT: but XCode works fine, i now compiled the driver. That first line must be incorrect.

[Wouter1]

The error disappears if I set in project the Apple Clang-Preprocessing / Preprocessor macros add TARGET_OS_OSX=1

EDIT: This seems indeed needed. When I remove it the build fails.

But then a new error appears in EMUUSBAudioDevice.h line 249 Invalid operands to binary expression ('nullptr_t' and 'UInt8')

[Wouter1]

If I change that line the NULL to 0 I get another error

IOKit/usb/IOUSBLog.h' file not found
