ProC compiles the .pc file and generates the below signature for the sqlcxt

extern void sqlcxt (void **, unsigned int *, struct sqlexd *, const struct sqlcxp *);

Even though sqlcxt is included in the orasql9.lib/orasql8.lib it fails to link it because of C naming convention.
This mostly happens if u genrate c++/.cpp files from the ProC or rename the .c files to .cpp, which requires extern "C" linking to be specified explicitly for VC++.

Update the above line in the .cpp file to

extern "C" void sqlcxt (void **, unsigned int *, struct sqlexd *, const struct sqlcxp *);

The only change is just adding "C" to the generated function declaration.

And there u go.

Were you able to fix the issue of undefined symbol sqlcxt?

I have made the change in .c file of the program being created as mentioned by you:

extern "C" void sqlcxt (void **, unsigned int *,
struct sqlexd *, struct sqlcxp *);

However, it gives me the following error:
mots_interface.c:117: error: parse error before string constant

Could you please suggest as to what am i missing here? Is there any header file which is not getting included? the libclntsh file is being included ib the makefile I have.

Any help in this regard would be highly appreciated.
