Re: [Texmacs-dev] Experimental Qt port

[Juan Pablo Romero Méndez]

Now it compiles with just one change:

in src/Plugins/Qt/QTMGuiHelper.hpp

line 45:

virtual int QTMStyle::pixelMetric(PixelMetric metric, const
QStyleOption *opt, const QWidget *widget) const;


gcc 4.2.1 requires:

virtual int pixelMetric(PixelMetric metric, const QStyleOption *opt,
const QWidget *widget) const;


The problem is in execution; it seg faults with any keystroke.

I've tried debugging it, but I'm not sure how. I tried launching "gdb
texmacs.bin procID"

this is the result of "bt":
