[SOLVED] Compiling Qt5 bindings (libQt5Pas.so)

[Blaazen]

Hello,

I need help with compiling Qt5 bindings. I follow the ../lcl/interfaces/qt5/cbindings/README.TXT and I got this error:

Are the Qt5 versions too different (5.6 .1 vs 5.15.12)?

Thanks.

I have not such problem. Maybe you compiled libQt5Pas in same directory and there's stalled .qmake.stash file ? Did you install dev packages of qt , so all include files are in /usr/include/qt5 ? Also, there can be few qmakes on disc, check if that one is for qt5 (not for qt4 or qt6).

Hi
I used "qmake-qt5" instead of "qmake" when I had similar errors, it worked like a charm...
HTH

I had no dev packages installed. That was it.

Thanks.
