Question

I am pretty experienced writing my own code, but not in C++. I am used to adding .NET assembly references, and I want to get into using C++.

I downloaded a VC++ 6 project presenting a graph algorithm, opened it in Visual Studio 2010 Ultimate and downloaded the required libraries (LEDA .NET assemblies) however, they came with both DLLs and LIB so I thought I would have no problems with the .NET and C++ connection. Also, the LEDA project comes with C++ style .header files, and static libraries, yet frustration persists.

I put my LEDA header files in a directory visible to the project, since I can “Go to definition” of all the custom LEDA data types and see where they are defined in the LEDA include files.

But, I can not compile/link these data types in. The VS finds their very existence repulsive, and refuses to acknowledge they could possibly be found in leda.lib.

Steps I have already taken:

1. Added additional /LIBPATH path under Properties ->Linker->General
2. Added explicit lib references under Properties->Linker->Input
3. Added all the paths containing LEDA header files and libraries to every path location I can find, like include path, reference path, library path.
4. Copied the DLLs and LIBs to the release folder as well as the base folder of the project.
5. Added a #pragma comment( lib, “leda” )

Still no joy.

It’s quite bad since none of the custom typedefs are recognised the errors balloon to 646 errors.

If anyone is kind enough to offer assistance, thank you.

I can’t guarantee this will work but try the following steps (therefore using it’s default predefined paths instead of setting your own ones) :

1) Copy *.dll into Windows/System32 or / and (there is some confusion about x64 and x32 default checking in my head :)) Windows/SysWOW64.

2) Copy *.h files into x:\PathToVC2010\include\

3) Copy *.lib files into x:\PathToVC2010\lib\
