Srinivas, Are you able to compile and link the demo programs? Before attempting to debug a custom PRO*C program, first ensure that you can compile and link any of the demos in "$ORACLE_HOME/precomp/demo" without problems. If you do experience problems compiling the demos, then log a TAR... Hope this helps... -Tim on 10/4/04 5:11 AM, Srinivas T at SrinivasT@xxxxxxxxxxxxxxx wrote: > Hi, > This some what error related to my proc application. > I am unable to compile my pro*c program on vc++ 6.0 version.. > and I am getting the following error. > Cpp1.obj : error LNK2001: unresolved external symbol "void __cdecl sqlcxt(void > * *,unsigned long *,struct sqlexd *,struct sqlcxp const *)" > (?sqlcxt@@YAXPAPAXPAKPAUsqlexd@@PBUsqlcxp@@@Z) > Debug/Cpp1.exe : fatal error LNK1120: 1 unresolved externals > Error executing link.exe. -- //www.freelists.org/webpage/oracle-l
