Pro*c errors in 11g. -- Compiles fine in 10g.

Question

Hi,
We are planning to migrate from 10g to 11g so started compiling our Pro*c code in to 11g. Got several errors and couldn't trace. So to investigate further I have written a basic pro*c program as follows:
#include <stdio.h>
#include <sqlca.h>
/*#include <sqlcpr.h>*/
#include <oraca.h>
#include <sqlda.h>
/* Declare error handling function. */
void sql_error();
int main(int argc, char** argv)
char user[]="myusername";
char pwd[]="mypassword";
char msg_buf[51]="";
/* Register sql_error() as the error handler. */
EXEC SQL WHENEVER SQLERROR DO sql_error("ORACLE error\n");
EXEC SQL CONNECT :user IDENTIFIED BY :pwd;
EXEC SQL
INSERT INTO hello_world
VALUES ('Hello world!');
EXEC SQL COMMIT;
EXEC SQL
SELECT msg
INTO :msg_buf
FROM hello_world
WHERE rownum <= 1;
printf("%s\n", msg_buf);
return(0);
void sql_error(char *msg)
char err_msg[128];
int buf_len, msg_len;
EXEC SQL WHENEVER SQLERROR CONTINUE;
printf("%s\n", msg);
buf_len = sizeof (err_msg);
sqlglm(err_msg, &buf_len, &msg_len);
if (msg_len > buf_len)
msg_len = buf_len;
printf("%.*s\n", msg_len, err_msg);
EXEC SQL ROLLBACK RELEASE;
exit(1);
}And then did the following:
proc iname=hellodb.pc MODE=ORACLE it has created a .c file.
Now run
/opt/ansic/bin/cc -g  -I. -I${ORACLE_HOME}/precomp/public -c hellodb.c -o hellodbwhich gave me a big list of errors / warnings.
"hellodb.c", line 117: warning #2837-D: omission of explicit type is
          nonstandard ("int" assumed)
  extern sqlcxt ( void **, unsigned int *,
         ^

         ^
"hellodb.c", line 123: warning #2837-D: omission of explicit type is

  extern sqlorat( void **, unsigned int *, void * );
         ^
"hellodb.c", line 316: warning #2223-D: function "sqlglm" declared implicitly
  sqlglm(err_msg, &buf_len, &msg_len);
  ^
"hellodb.c", line 342: warning #2223-D: function "exit" declared implicitly
  exit(1);I did the same in another server which is having 10g installation and it went on well and created the exe hellodb.
Any idea what these errors are?
Thanks in advance,
Deep.

Answer 1

Hello,
We face the similar problem.Our database is migrated to 11.2.0.2 from 10g.
PRO*C compilation is not happening with so many warnings and 1 error below
error #4313-D: no prototype or definition in scope for call to memory allocation routine "malloc".
Could you please provide the solution.
we are using the following command to compile PRO*C
make -f $ORACLE_HOME/precomp/demo/proc/demo_proc.mk EXE=$program OBJS=$program.o PROCFLAGS="sqlcheck=full userid=<username>/<password>@oraclesid" build
