Dynamic loader taking function from wrong lib

rimon · #1 (**permalink**) 01-08-2008

Hi,

I have two dynamically loaded libraries (shared objects), both of which include functions of the same name - foo. When I call 'foo' from libA, it takes it from libB, although it is implemented in libA as well. Since we need the function to be called from libA, we tried linking it with the flag -bSymbolic, to no avail. It still called the function from libB.

Specifics: Working on HP 11.23, compiling with HP gdb 5.7.4.

Background: In this case libA is an ODBC driver we've written. libB is the unixODBC driver manager. The way these works is that in our driver we implement a set of SQLxxx functions, which have the same names as the set of functions in the driver manager. When the driver manager loads our ODBC driver, it knows to call the SQLxxx functions from our driver. Our problem is in a case where we call our own SQLxxx function from within our own driver, and it calls the function from the driver manager instead!

Ideas?

Thanks.
