[Scons-users] MS Visual Studio Install tries to find a not-existing file

[Kraus Philipp]

Hi,

yes I'm developing primary under unix systems, so there exists a *.so or/and *.a file and they are independed.
I will read the chapter, but how can I realize this in / with scons? I would like to link the DLL in my program

Should I create a env.Library first and pass the result to env.SharedLibrary and this output to the env.Install?

Thanks

Phil

Linux doesn't define something like that, I suggest you read the MSDN chapter on shared libraries and exported functions/classes/methods/...

If you don't export functions, it means that you won't be able to link against it, only load it with something like "LoadLibrary".
