Fatal Error C1189

Error Message

#error : user supplied error message

C1189 is generated by #error.

For more information, see The #error Directive.

The following sample generates C1189:

// C1189.cpp
#undef _WIN32
#if !defined(_WIN32)
#error _WIN32 must be defined   // C1189
#endif

You may also see this error if you build an ATL project with the /robust MIDL compiler option. /robust is only for use when building for a Windows 2000 or later machine. So, either remove /robust or change this line in the dlldatax.c file:

#define _WIN32_WINNT 0x0400   // for WinNT 4.0 or Win95 with DCOM

to

#define _WIN32_WINNT 0x0500   // for WinNT 4.0 or Win95 with DCOM

To remove /robust, specify /no_robust in the Advanced property page in the MIDL property page folder. See MIDL Property Pages: Advanced for more information.
