Microsoft mangles both function *and* variable names in C++. The result was unresolved symbol error during the link. Wrapping a variable in C_MODE_START/C_MODE_END definitely helps in this case. >, do you remember if one tried adding a > C_MODE_START/C_MODE_END around the "extern LOCK_uuid_generator" of > mysql_priv.h If I remember correct, this was my first try, but then serg noticed that 2 UUID generators( "normal" uuids and "short" ones) are completely different things and do not have to wait for each other.
