ProjectGenerator Error v0.9.2

I just installed OF v0.9.2 and moved from C::B to Qt Creator,
i got the same error until i run “”

Now i got new error:

Command failed: /bin/sh -c "projectGenerator"  -o"/usr/local/OF_v0.9.2" -a" " -p"linux64" "/usr/local/OF_v0.9.2/apps/myApps/mySketch1"
terminate called after throwing an instance of 'std::regex_error'
  what():  regex_error
Aborted (core dumped)

Any ideas ??

Also, when i compile ofQt return this error:

/home/grg/Documents/C++/FRAMEWORK/ofQt/of_v0.9.0/libs/openFrameworks/video/ofGstUtils.h:12: erreur : gst/gst.h: No such file or directory
#include <gst/gst.h>

…does it run only with OF v0.9.0 ?

Ok!.. it must come from my old gcc…

if you are using qtcreator, the IDE plugin allows you to create new projects add addons easily
