Thread: ECPG error message

Hi all,


When I try to compile source code with these variable declarations:
 18 EXEC SQL BEGIN DECLARE SECTION; 19 struct FIELDS_t { 20     char         cod[16]; 21     long double  val; 22 }
fields;23 char command[100]; 24 EXEC SQL END DECLARE SECTION;
 
 $ ecpg -t -I /usr/local/pgsql/include -o tstexecute.c tstexecute.ec

I get this error message:
 tstexecute.ec:20: ERROR: parse error at or near "double"

What's the problem with long double?
Isn't it a standard C data type?

I'm using PostgreSQL 7.1.2, compiled with options:     --with-tcl --enable-locale --enable-multibyte=LATIN1

and my system is a:
 Linux version 2.2.16-13cl ( root@mapi2.conectiva.com.br 
<mailto:root@mapi2.conectiva.com.br> ) (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #1 seg jun 26

ecpg does not know long double.

Is it? Is it available on non-gcc compilers too?

"long double" doesn't exist in ANSI C; it's a new feature of C99.

Since we have no backend datatype that corresponds to long double,
I don't see any strong reason for ecpg to support it.
