CGAL users discussion list

Dear Mahmood Naderan,
 
I am sorry to disturb you again.
 
As you told me, I complied the CGAL_80.sln in the "src" folder, and succeeded. Then I add the cgalqt-vc80-mt.lib to the project. But I got the new Error:
 
" 1 fatal error LNK1181: cannot open input file 'qt-mt3.lib' Straight_skeleton_2 "
 
At the same time, I can run other examples in "C:\Program Files\CGAL-3.3.1\examples" folder without Qt in CGAL and the Qt examples in "C:\qt-3\examples" folder smoothly.
 
I am confused...
 
Thanks and cheers.

Xintao.
