CGAL users discussion list

[Qianqian Fang <>]

just realized that the my original thread was hijacked by this new thread. 

Anyway, let me make it easier for people to find my original question, attached is the code I am trying to compile, you can simply save it to CGAL-3.4-beta1\examples\Surface_mesher\, and I appreciate if anyone can send me the compiled binary (with cgal 3.4beta) for windows.

I am using "Microsoft Visual C++ 2005 Express Edition", and things are almost fine for 3.3 (not the static linking bit), but I am trying to compile my code against 3.4 beta, which I can not even set up the makefiles.

I am still hoping that someone who had set up 3.4 on a windows machine can help me compile a binary; but if I have to set up my own copy, the following is my "cmake ." output, all default installation, seems a bunch of libraries are missing and I don't know how to do with them (I don't know where to find boost_thread; GMP and MPFR are underCGAL-3.4-beta1\auxiliary, but cmake could not find them; where can I download zlib and what should I do to let cmake know where to find?)

If your first mail of the current thread, you forgot to tell us an interesting
information: your compiler name and version¹. You say your are using VC2005.
Have you tried both Debug and Release configurations? Have you installed the
service pack 1 of VC2005?

¹) See http://www.cgal.org/bug_report.html


Actually maybe there is a problem using CGAL libraries with a static runtime.
That setup has not been really tested on Windows, as far as I know.
