Description:
Dear,
I trying to migrate my application developed using Pro*c to ECPG. But, when
I run the code below with "ecpg -c" command to generate c code, the syntax
for typedef generated appears to be wrong. Below is an sample code and the
steps to generate error return by C compiler due the wrong syntax for
typedef.
Step 1: Create a file with pgc extension with the code below:
#include <stdio.h>
EXEC SQL TYPE t_char_10 IS char[10];
int main()
{
int status = 0;
return status;
}
Step 2: pre compile the file with command: ecpg -c file.pgc. This command
will generate the c code below. Note that the syntax for typedef is wrong.
/* Processed by ecpg (4.10.0) */
/* These include files are added by the preprocessor */
#include <ecpglib.h>
#include <ecpgerrno.h>
#include <sqlca.h>
/* End of automatic include section */
#line 1 "example.pgc"
#include <stdio.h>
typedef char [ 10 ] t_char_10 ;
#line 3 "example.pgc"
int main()
{
int status = 0;
return status;
}
Step 3: Try to compile the c code with command "cc -I/usr/pgsql-9.4/include
-c file.c".
file.pgc:3 error: expected indentifier or '(' before '[' token
best regards,
Gláucio
