创建dll时找不到依赖项

Question

I try to create a dll from all of my classes with VS command prompt but all classes using externall dll's won't do.

The program uses some dlls from OpenGl that I stored in the bin folder and it works fine while running the program

But I get error CS0246, namespace could not be found, missing directive when I try to create a dll from all those classes.

The line I use is:

csc /target:library /out:Engine.DLL *

All System namespace are found but all external dlls are not.

Do I need to add a path to the external dlls in VS environment?

Answer 1

You certainly need to use the /reference (or /r ) compiler option for your external assemblies ( here is the official documentation from msdn):

csc /target:library /r:Assembly1.dll;Assembly2.dll out/Engine.DLL *

/lib could also be useful if your external assemblies are located in different folders and if you don't want to use /r with a full path (like /r:../test/folder/subfolder/Assembly1.dll )
