    Description

      From my_global.h :

      #if HAVE_DLERROR
      		 
      #define dlerror() ""
      		 
      #endif

      Why is that?

      For comparison, in MySQL my_global.h :

      #ifndef HAVE_DLERROR
      		 
      #ifdef _WIN32
      		 
      ...
      		 
      #define dlerror() ""
      		 
      #define dlopen_errno GetLastError()
      		 
      #else /* _WIN32 */
      		 
      #define dlerror() "No support for dynamic loading (static build?)"
      		 
      #define DLERROR_GENERATE(errmsg, error_number) errmsg= dlerror()
      		 
      #define dlopen_errno errno
      		 
      #endif /* _WIN32 */
      		 
      #else /* HAVE_DLERROR */
      		 
      #define DLERROR_GENERATE(errmsg, error_number) errmsg= dlerror()
      		 
      #define dlopen_errno errno
      		 
      #endif /* HAVE_DLERROR */

      MySQL my_global.h (rightfully) redefines dlerror() if HAVE_DLERROR is not defined, while MariaDB client library redefines dlerror() if HAVE_DLERROR is defined.

          The consequence of this is that if I include my_global.h , dlerror() doesn't work anymore and I can't verify if dynamic linking loader is working correctly.

          The workaround I am using is to add the follow after I include my_global.h :

          // MariaDB client library redefines dlerror(), see https://mariadb.atlassian.net/browse/CONC-101
          		 
          #ifdef dlerror
          		 
          #undef dlerror
          		 
          #endif
