    Unresolved external symbol since migration to_X64

    Visual Studio 2015

    Unresolved external symbol since migration to_X64

    Our Dll has Error LNK2001 unresolved external symbol _DllRegisterServer@0 error since we did the Migration To X64

    we need this function for registration with regsv32 therefore we want to export this function with

    # pragma comment(linker, "/EXPORTllRegisterServer=_DllRegisterServer@0,PRIVATE")


    how can it be that we have the unresolved exernal Symbol after migration to X64 which worked for X86 with the same code

    has the .dll been built for x64?

    That pragma should not be necessary I think.
    Can you post your DllRegisterServer code?

    A quick search brought me to: https://stackoverflow.com/questions/...esolved-smbols
    There they say to remove the pragmas.
