C::B error compiling

[thwhisper]

I am trying to set up a gtk project using the new 12.11

I already included the path in the system var C:\gtk

but when i try to use the wizard in CB and compile the code it produces an error saying
error: use -E or -x for standard user input

I have all the gtk libs lastest version bundle 2.2 somthing so i know is not gtk

what is this ???
