hi all,
#I m trying a Pro C program.
#I m using Oracle9i DB preCompilier..
#The file temp.pc contains..
/////////////////temp.pc starts///////////////////////////////
#include <stdio.h>
#include <string.h>
EXEC SQL INCLUDE sqlca.h ;
void main()
{
EXEC SQL BEGIN DECLARE SECTION;
char *url = "QMRS.SUTRASYSTEMS.COM";
char *user = "qmrs";
char *pwd = "qmrs";
char data[30];
EXEC SQL END DECLARE SECTION;
EXEC SQL CONNECT :user IDENTIFIED BY :pwd USING :url;
EXEC SQL SELECT VAL INTO :data FROM TMP;
printf("val: %s\n", data);
}
/////////////////temp.pc ends///////////////
#The above file precompiles properly "temp.c" file is generated.
#I m using Turbo C for Compiling the temp.c file.
compiles fine but gives a linking error
Linker Error: Undefined symbol _sqlcxt in module
#i have included the libraries from {ORACLE_HOME}\precomp\lib\msvc\oraSQL9.lib
in the lib dir of TCC ie D:\TCC\LIB
Still the problem persists please help me out if any one has a soln
thanks in advance

Thanks Tahpush For the Help..
i was Finaaly able to run it with few Changes..
1. Used Visual Studio C++ IDE
2. Renamed File genereted from C to CPP
3. Made changes in the code as shown in code below in RED color
4. Used External Libtrary {ORACLE_HOME}\precomp\lib\msvc\oraSQL9.lib for building..

NAME
SQLCA : SQL Communications Area.
FUNCTION
Contains no code. Oracle fills in the SQLCA with status info
during the execution of a SQL stmt.
NOTES
**************************************************************
*** ***
*** This file is SOSD. Porters must change the data types ***
*** appropriately on their platform. See notes/pcport.doc ***
*** for more information. ***
*** ***
**************************************************************
If the symbol SQLCA_STORAGE_CLASS is defined, then the SQLCA
will be defined to have this storage class. For example:
#define SQLCA_STORAGE_CLASS extern
will define the SQLCA as an extern.
If the symbol SQLCA_INIT is defined, then the SQLCA will be
statically initialized. Although this is not necessary in order
to use the SQLCA, it is a good pgming practice not to have
unitialized variables. However, some C compilers/OS's don't
allow automatic variables to be init'd in this manner. Therefore,
if you are INCLUDE'ing the SQLCA in a place where it would be
an automatic AND your C compiler/OS doesn't allow this style
of initialization, then SQLCA_INIT should be left undefined --
all others can define SQLCA_INIT if they wish.
If the symbol SQLCA_NONE is defined, then the SQLCA variable will
not be defined at all. The symbol SQLCA_NONE should not be defined
in source modules that have embedded SQL. However, source modules
that have no embedded SQL, but need to manipulate a sqlca struct
passed in as a parameter, can set the SQLCA_NONE symbol to avoid
creation of an extraneous sqlca variable.

Problem:
I am building my application in Red Hat Linux. My Pro*C code compiles fine but while linking I was getting the following error:
undefined reference to `sqlcxt(void**, unsigned int*, sqlexd*, sqlcxp const*)'
Solution:
Using the tip from umrigar_kunal above, I edited the .c file, and inserted "C" as follows:
/* SQLLIB Prototypes */
extern "C" void sqlcxt (void **, unsigned int *, struct sqlexd *, const struct sqlcxp *);
extern "C" void sqlcx2t(void **, unsigned int *, struct sqlexd *, const struct sqlcxp *);
extern "C" void sqlbuft(void **, char *);
extern "C" void sqlgs2t(void **, char *);
extern "C" void sqlorat(void **, unsigned int *, void *);
Now, I am able to link and create the executable.
Thanks umrigar_kunal!!!
Is there a Pro*C flag that can create these extern declarations with the "C" literal? I wonder.
