Problem: When I try to use the InterBase API in a C++Builder 3 project I get Linker errors like the following: [LinkerError] Unresolved external '_isc_start_transaction' referenced from ... A few of the InterBase API functions are defined in ibase.h using the __cdecl calling convention. The C++Builder incremental linker prepends an underscore to these functions. The gds32.dll does not export these functions with an underscore, thus the Unresolved external error message. Solution: One solution is to add a module definition file to your project that creates an alias for the function. Here is an example .def file that resolves the error for the isc_start_transaction function --------------------- begin .def file ----------------------------- IMPORTS _isc_start_transaction = GDS32.isc_start_transaction --------------------- end .def file -----------------------------
