where is the error??

[mahmoodn]

Hello,
when I make, the output does not show exactly where is the problem. here is the output of "make":

/usr/lib/qt-3.3/bin/moc -o VVc_demo.moc  VVc_demo.cpp
g++ -I../../include -I../../../Arrangement_2/include -ggdb -Wall  '-I/home/naderan/CGAL-3.2/include/CGAL/config/i686_Linux-2.6_g++-3.3.3' '-I/home/naderan/CGAL-3.2/include'  -I/usr/X11R6/include       -I/usr/lib/qt-3.3/include       -DCGAL_USE_CGAL_CORE    -c VVc_demo.cpp

   std::vector<typename

VVc_demo.cpp:289:   instantiated from here
../../include/CGAL/VVc_diagram_2.h:956: warning: unused variable `bool flag'
make: *** [VVc_demo.o] Error 1

So where is the error??? the warning should not produce ant error.

Regards,

I would look at line 410 for the error.

Oh, yes. I thought that gcc stop right after an error. but seems that it continue compiling and at end it generate a report.

Thanks,

If you use 'make -k' that is true, but eliminating '-k' should cause
the compile to stop on or near the error.

Thank you. the problem was I did not notice that the error is actually reported, I was confused that whether the warning caused the error 1

now that I know where is the problem I can resolve it. it was a simple mistake

Thanks again,
