I've done some testing and apparently it is a problem with Qt 4.4/X11
(I've used Qt 4.4.3/X11 and it show the same bug). Using Qt 4.3.5/X11
seems to work fine (modulo of course known bugs in the TeXmacs code).

Ok, now I've set TEXMACS_PATH and GUILE_LOAD_PATH properly and

I'm using Qt 4.4.0

Attached is the output of gdb.

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":
(gdb) r
The program being debugged has been started already.
Start it from the beginning? (y or n) y

If you want to debug by calling directly the executable I think you
should
properly set TEXMACS_PATH and GUILE_LOAD_PATH before.
Also, what verision of Qt do you have?
