I know that. I am precisely trying to use the locale class !
Here is my test program
//-------------------------------------------------------
#include <locale>
#include <iostream>
using namespace std;
int main(int argc, char *argv[])
{
char *loc = "";
if (argc > 1) loc = argv[1];
cout << "Trying locale : " << loc << endl;
locale::global(locale(loc));
return 0;
}
//-------------------------------------------------------
If I compile it with g++-3.4 or g++-4.0.0, the compilation is fine, but
at run time I get an std::runtime_error if I try any locale except C and
POSIX ! For instance
5-kheops% locale fr_FR
Trying locale : fr_FR
terminate called after throwing an instance of 'std::runtime_error'
what(): locale::facet::_S_create_c_locale name not valid
zsh: abort locale fr_FR
5-kheops%
or
5-kheops% locale de_DE
Trying locale : de_DE
terminate called after throwing an instance of 'std::runtime_error'
what(): locale::facet::_S_create_c_locale name not valid
zsh: abort locale de_DE
5-kheops%
But, if I compile this programm with g++-3.3.2, it does not throw. And
the locales are corrrectly installed on my machine and setlocale() works
with C...
Thus I guessed (maybe wrongly) that it had something to do with my
configuration when building gcc-3.4 and gcc-4 ,
Any help would be appreciated.
