building static Qt6 results in ABI "unknown"

mzimmers

Hi all -

I tried building a static Qt installation (on Windows) using the steps on this page. The build seems to work, but when I add my new Qt version in Creator, the ABI shows as follows:

ABI: unknown-unknown-unknown-unknown-unknown

Obviously, I can't build with this.

Anyone have an idea what I might have done wrong here?

Thanks...

Which compiler did you use to build on Windows?

@cristian-adam presumably the one in my PATH environment variable: C:\Qt\Tools\mingw1120_64\bin.

EDIT:

C:\Qt\Tools\mingw1120_64\bin>g++ -v
Using built-in specs.
COLLECT_GCC=g++
Target: x86_64-w64-mingw32

EDIT 2:

Actually, this doesn't appear to be the case -- I had installed Strawberry Perl which included its own toolchain, and appears ahead of C:\Qt\Tools\mingw1120_64\bin in my PATH. The version in Strawberry is GNU 8.3.0.

I'll get my IT department to remove Strawberry and see if that changes things.

BTT. Anyone?

Thanks...

The above information comes from Qt Creator, and for some reason parseCoffHeader function is not detecting the ABI of your qmake executable.

I think this is good enough for a bug report at https://bugreports.qt.io/ with the executable attached 😊

Last time I checked a static build of Qt, I used the MSVC compiler, and worked fine. MinGW 11.2.0 might have a problem.

Done.

Thanks. I'll keep this open until I get some resolution on it, then summarize it here.

@cristian-adam I see you're the assignee on this. Feel free to contact me if you want any more information, or want me to try something.

This has been fixed in a development release of Creator 8.0.0 beta 2, and can be found here. Marking as solved. Thanks for the help.
