I have a Qt stub application and I keep getting compiler errors
#include <QApplication>
int main(int argc, char *argv[])
{
return 0;
}
I used the commands qmake -projectand qmake, and as far as I can tell, they did their job correctly. When I subsequently call makethe command line, I get the following error:
g++ -c -O2 -frtti -fexceptions -mthreads -Wall -DUNICODE -DQT_LARGEFILE_SUPPORT
-DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_THREAD_SUPPORT -DQT_NEEDS_QMAIN -I

ult' -o release/Main.o Main.cpp
cc1plus.exe: Invalid option 'threads'
make[1]: *** [release/Main.o] Error 1
make: *** [release] Error 2
My google searches tell me that multithreading is important, but not how to fix this error. Any help would be appreciated.
EDIT (copied from the answer on the left):
Now I get:
