Hello, may be you can help me with my problem about language localization. As I read in the documentation, for example "setlocale( LC_ALL, "German" );" is the common way to set the language localization. But this will be valid for the whole program and it is not that what I want and need. While programming with C++, there's the possibility to create a "locale" object and imbue a stream with it. Then this language localization is only valid for this stream and its life cycle. That is what I want and need. Here a small example: std::ofstream OutFile; std::locale Local_German( "German" ); OutFile.imbue( Local_German ); My problem is now, that this code is compilable, but while the program is running and would create this object 'Local_German', it crashes. I checked this with several locale strings like "C", "", "English" and some more. With the first two, the locale object is created well and the program is running well. But with any other local string it crashes. What's wrong with this ? Is there anything missing on my SuSE 8.1 with gcc 3.2 system ? Any comment helping me to solve that problem is welcomed !
