Pro*C/VC++/NT: struct sqlca already defined???

Hi everybody,

using Pro*C in a VC++/NT environment I have the following problem:

In two of the modules I included the sqlca.h file. During the link process the linker claims about "one or mor multiply defined symbols found":

"struct sqlca sqlca" (?sqlca@@3U0_at_A) already defined in ...

How can I access the sqlca structure in different modules without causing the linker to fail???

TIA,
