Using catopen/catgets for international programming

lchxr · 12-15-2009, 09:57 AM

I want to use catopen/catgets for international programming. I understand how to write a message source file, e.g. hello.msg and use 'gencat' to create a catalog file (.cat), and then use it in my C function.

Code:

gencat -o hello.cat hello.msg

In my hello.msg, I have

Code:

$set 100
10 "hello, world"

My question is: whether or not I can use #include "hello.h" in hello.msg file

for example, in hello.h

Code:

#define MSG_HELLO 10

in hello.msg

Code:

#include "hello.h"
$set 100
MSG_HELLO  "hello, world"

I have tried, but failed.

Does anyone know any method to extract a symbol from .h file and include it into .msg file?

Thank you.

Suggest GNU Gettext as a much easier to use and more standard way to do translations of programs. It also does translation at run-time, so you don't have to recompile your program for new languages, just ship extra .mo files.
