System Configuration
---------------------
Architecture :
Intel Pentium III
Operating System :
Linux 2.4.19 with glibc 2.2.5 (SuSE v8.1)
PostgreSQL version :
PostgreSQL-7.2.3
Compiler used :
gcc v3.2
Please enter a FULL description of your problem:
------------------------------------------------
Postgresql itself compiles like a breeze, no problem there.
Config line: "./configure --with-openssl --with-perl --with-CXX"
Upon compiling TrollTech's Qt-library with postgresql support, the process
fails on numerous lines in pg_type.h with the following message:
> In file included from sql/drivers/psql/qsql_psql.cpp:49:
> /usr/src/postgresql/src/include/catalog/pg_type.h:196: declaration of
> `int*
> __errno_location()' throws different exceptions
> /usr/src/postgresql/src/include/catalog/pg_type.h:195: than previous
> declaration `int* __errno_location() throw ()'
> [...]
Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
The problem is caused by lines such as:
DATA(insert OID = 16 ( bool PGUID 1 1 t b ... _null_ ));
DESCR("boolean, 'true'/'false'");
Since DATA and DESCR are defined in postgres.h:
/* these need to expand into some harmless, repeatable declaration */
#define DATA(x) extern int errno
#define DESCR(x) extern int errno
These lines are eventually expanded into:
extern int errno;
extern int errno;
Obviously, compiling the following source produces the same problem:
#include <errno.h>
extern int errno;
extern int errno;
Postgresql itself seems to never include <errno.h> along with
<catalog/pg_type.h>, otherwise it would suffer from the same problem
If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------
We might want to expand ( 'DATA', 'DESCR' ) into something else, one of them
anyway ;-)
