harfbuzz (TeX Live)

Mentore:
Hello all,
I'm in the process of compiling the latest version of TeX live for OS/2.
I just stopped with a really strange error (make log attached) regarding namespaces and I can't wrap my head around it.
Searching this forum for harfbuzz I found it in the wonderful Qt6 development thread from the GOAT, Paul Smedley, so the question is:
is harfbuzz somehow available under OS/2? Or, on a second instance, is it possible to work around this (for me) never seen problem?

I feel we could use a new TeX version...

Thanks all
Mentore

Dave Yeo:
As far as I know, harfbuzz has always simply compiled. Programs do change, the harfbuzz in the Mozilla tree doesn't have hb-ot-face.hh but it is relatively old. Don't have the Qt source handy here.

Paul Smedley:
Looking at https://github.com/psmedley/qt6-base-os2/tree/main/src/3rdparty/harfbuzz-ng it seems there were no OS/2 specific patches.

Something rings a bell about harfbuzz failing to build at some point, can you post the error you're getting and a link to the source?

Dave Yeo:
Mentore posted the error already. Harfbuzz is at hrafbuzz.org. Guess they've moved to Meson for building otherwise I'd try

Steven Levine:
This is the first time I have looked at this code, so I could easily be way offbase.

As I read the code, in Paul repo, while there may be no OS/2 specific patches, the there is OS/2 specific code.

I suspect the error is because OS2 has been defined in some header and the code does not expect this.  Here's a testcase that generates a similar error

#define HB_OT_TABLE(Namespace, Type) namespace Namespace { struct Type; }
#define OS2 4.5
namespace OT { struct OS2; }

compile this with g++ -c.
