Set the program's locale prior to calling libpq functions.

I did not try it on Windows, but Microsoft seems to work like
UNIX in that respect:

http://msdn2.microsoft.com/en-us/library/x99tb11d(VS.80).aspx

Try something like

setlocale(LC_MESSAGES, "Spanish");

or, if your language environment is Spanish, simply

setlocale(LC_MESSAGES, "");

Thank you for your reply

but I got the error 'LC_MESSAGES' : undeclared identifier

locale.h only defines LC_COLLATE, LC_CTYPE, LC_MONETARY, LC_NUMERIC, LC_TIME

I tried to set a system variable LC_MESSAGES, but didn't work

Then, I tried to find more information


In libpq, when ENABLE_NLS is not defined,
#define libpq_gettext(x) (x)

If I set ENABLE_NLS to 1, then I think I need the gettext library, because
it needs <libintl.h>

so, there is no simple way in windows to get messages in spanish within
libpq before connecting to server, is correct?

thanks

I got it to work with this program:

#include <stdlib.h>
#include <stdio.h>
#include <locale.h>
#include <libpq-fe.h>

int main(int argc, char **argv) {
        PGconn *conn;

        setlocale(LC_ALL, "");
        putenv("PGLOCALEDIR=C:\\Programme\\postgres\\share\\locale");

        conn = PQconnectdb("port=4711");
        if (CONNECTION_OK != PQstatus(conn)) {
                fprintf(stderr, "%s\n", PQerrorMessage(conn));
                PQfinish(conn);
                return 1;
        }

        PQfinish(conn);
        return 0;
}

Instead of setting PGLOCALEDIR in the code, you can also define
it as environment variable on your system, that is maybe better.

It must point to the directory where your message files are installed
(you have spanish message files installed, haven't you?).

The above program assumes that there is no database running
on port 4711, so you get an error message from libpq.

Thank you very much for your help.  It worked for me.

I am using Visual C++ 2005 express
I downloaded gettext-runtime-0.13.1.bin.woe32.zip and
libiconv-1.9.1.bin.woe32.zip from
http://sourceforge.net/project/showfiles.php?group_id=25167

Then I compiled libpq with ENABLE_NLS, gettext and libiconv libs

They, I just got carefull with PGLOCALEDIR,

again, thank you!
