Hi,
Â* I’m trying to debug into the Qt libraries for our application, however I need to use “qmake-qt4 –query “ from the /usr/debug folder (we’re using FindQt4.cmake), but qmake-qt4 is not executable, and if it is ‘chmod +x’ it complains about not being able to execute binary file.
Â*
This is running on a 32bit VM, running maverick,

matthew@matthew-VirtualBox:/usr/lib/debug/usr/bin$ file qmake-qt4

What do I need to do to use the debug libraries?
Â*
Thanks in advance.

Why do you need to use qmake from /usr/debug? The
/usr/lib/debug/usr/bin/qmake-qt4 file is the debugging symbols from
/usr/bin/qmake-qt4

To debug use of Qt4 libraries you just need the debugger (usually gdb)
to know to load the symbols from /usr/lib/debug/ which gdb will do
automatically.
