Question

I have a large program with several large DLL’s that are compiled with MFC and /clr. There is a limit of 65535 global FieldRVA entries in an assembly. If it is more the loader raises an exception. I already have Enable String Pooling (/GF).

I have alot of code like:

static char *pSTRING_ONE = "STRING_ONE";

if I compile witha macro such as:

#define pSTRING_ONE  "STRING_ONE"

it greatly reduces string for the CLR meta data so I compile but then I gain all of the problems of using a #define.

The question is: Is there another alternative to changing the static char * -> #define ?

Answer 1

Unfortunately, the best solution to our problem was to include the offending code within a class.

// Old Way
static char *pSTRING_ONE = "STRING_ONE";

New

class CFieldDefs
{
  public:
     static char *pSTRING_ONE;
}

char *CFieldDefs::pSTRING_ONE = "STRING_ONE";

Usage:

CFieldDefs:pSTRING_ONE;

Even though the change was quite tedious, it greatly reduced the number of fieldRVA Entries CLR Fields within the DLL. Thanks for all your help.
