How to compile Botan crypton library as a static library in VC ++?

Question

I was extremely unsuccessful at compiling Botan as a static library in Visual C ++. The build.h file contains the following code:

#ifndef BOTAN_DLL
  #define BOTAN_DLL __declspec(dllexport)
#endif

This macro appears almost everywhere in the botanical code base, for example:

class BOTAN_DLL AutoSeeded_RNG : public RandomNumberGenerator

My understanding from the previous question is that all you have to do is define BOTAN_DLL without a value, and it should compile as a static library. However, this leads to a huge list of build errors, such as "missing tag name". Does anyone know how to do this?

EDIT . The following is an example of errors that result from adding / D "BOTAN_DLL" to the makefile:

        cl.exe /Ibuild\include /O2  /EHsc /GR /D_CONSOLE /D "BOTAN_DLL"  /nologo
 /c src\checksum\adler32\adler32.cpp /Fobuild\lib\adler32.obj
