Build/Make Error – ld: malformed file, unknown enumerated scalar, platform: zippered

ResistorInTheDark

My project fails to build.

Error Message:

ld: malformed file
/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/lib/libz.tbd:4:18: error: unknown enumerated scalar
platform:        zippered

 file '/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/lib/libz.tbd'
clang: error: linker command failed with exit code 1 (use -v to see invocation)

In the Issues tab, I get two errors:

malformed file
unknown enumerated scalar

For context, here's what libz.tbd (aliased to libz.1.tbd) looks like:

Further Attempts:

I tried editing the libz.tbd file and changed platform: zippered to platform: macosx. This generates a similar, but different error when I do a rebuild. Instead of libz.tbd, there is now an error with IOKit.tbd.

ld: malformed file
/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks//IOKit.framework/IOKit.tbd:4:18: error: unknown enumerated scalar
platform:        zippered
                 ^~~~~~~~
 file '/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks//IOKit.framework/IOKit.tbd'
clang: error: linker command failed with exit code 1 (use -v to see invocation)

This is what the IOKit.tbd file looks like (it's over 700 lines long, so I chose to only show the first 8):

--- !tapi-tbd-v3
archs:           [ x86_64 ]
uuids:           [ 'x86_64: 1170EC49-1912-3657-9C71-991653959191' ]
platform:        zippered
install-name:    /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit
current-version: 275
objc-constraint: none
exports:

Modifying IOKit.tbd and rebuilding led to the same error with OpenGL.tbd, then with libSystem.B.tbd, then with libc++.tbd. I reverted my edits and decided to go no further in case I damage my system or something.

I tried creating new, raw projects from project templates wizard (Cmd+N), but building them also failed with the malformed file, unknown enumerated scalar errors pointing to a platform: zippered line on either the IOKit.tbd or OpenGL.tbd file (randomly):

Projects -> Applications -> Qt Widgets Application
Projects -> Applications -> Qt Quick Application
Projects -> Felgo Games -> New – Empty Felgo 3 Project

Although I'm use Felgo API, I decided to post here since I was able to produce the issue with Qt Widgets and Qt Quick Applications.

Cleaning, running QMake, and rebuilding didn't work.
I tried upgrading my macOS version (from 10.14.3 to 10.14.4) and tried building the same applications to no avail. I'm getting the same errors.

Research:
Research was tough. All I found particularly useful and relevant was this Lazarus IDE forum thread (fairly recent, started 3-5 days ago). Not sure what to do with it. It does say something about updating CommandLineTools though...

Software Details:
OS: MacOS Mojave 10.14.3 and 10.14.4
IDE: QtCreator 4.7.0 – Based on Qt 5.11.1 (Clang 8.0 (Apple), 64 bit)
C Compiler: GCC (C, x86 64bit in /usr/bin)
C++ Compiler: GCC (C++, x86 64bit in /usr/bin)

I'm not sure where or how to proceed. Any thoughts?

Hi,

Did you also update Xcode ?
What version of Qt are you using ?

ResistorInTheDark

Hi @SGaist

I left Xcode alone. (My xcode-select version is 2354. There's an update in the App Store.) Should I upgrade it?

I'm using Qt 5.11.1.

Thanks

ResistorInTheDark

I think I got it!

The projects build if I change the compilers in the kit to Clang + doing a clean and rebuild. (That'd be the Clang (C/C++, x86 64bit in /usr/bin) options.)

The compilers were originally set to GCC. (Both GCC (C/C++, x86 64bit in /usr/bin) and GCC (C/C++, x86 64bit in /usr/local/bin) failed to build with the malformed file errors.)

Well, at least building works for now and development can continue. :-)

I'm still curious though, why GCC would do this. (Let me know if dumps from gcc -v would help.)

SGaist

Yes the dump would be nice.

Do you have any custom version of GCC installed on your system ?

ResistorInTheDark

@SGaist Here you go:

gcc -v (aka /usr/local/bin/gcc -v, from which gcc):

Using built-in specs.

gcc version 8.2.0 (Homebrew GCC 8.2.0)

I remember trying to upgrade my GCC version to ≥ 8 so that I could get my hands on std::optional and other cool C++17 features. Ended up using homebrew. Does this count as a custom version?

For context, I'll include the dump from /usr/bin/gcc as well, since I tried both /usr/local/bin/gcc and /usr/bin/gcc compiler options and both failed with malformed file etc.

/usr/bin/gcc -v:

Not sure if this is GCC at all. Looks like clang...

Hopefully this might help.

SGaist

Apple has stopped using GCC a long time ago.

You should configure your Kit to use Apple's official Clang compiler that comes with Xcode.

I don't know how well GCC 8.2.0 has been tested against the 10.14 macOS SDK.

ResistorInTheDark

Ah ok, good to know. Somehow GCC always seemed to work. Thanks for the help.
