ipe @7.2.11: error: no member named 'button' in 'QTabletEvent'

[matan-bebop (Andrii)]

There is a compiler error while building the port.

I first tried ipe +qt4 -qt5, which proceeds to compiling without the Xcode installed. Still, the build fails. Then I installed Xcode–no luck as well.

+qt5 requires Xcode, unlike +qt4. It also fails to build.

The log says the problem is:

    ipeDebug("TabletPress: %d %d", ev->button(), ev->pointerType());

4 errors generated.

Maybe this is a problem already solved by the developers of ipe and updating the port to a newer version would help. I appear to have assigned that ticket to myself but forgot about it and am not working on it.

Yeah, it fails for me also here:

16. S. Also this file has a wrong include: src/ipelib/ipebitmap_unix.cpp.

Changing it to #include <Carbon/Carbon.h> fixes the build, but then it fails on QTabletEvent issue.

And also src/include/ipeattributes.h misses #include <cstdint>.
