Bug ID: 119105
Summary: std::locale only working with C and POSIX
Product: gcc
Version: 14.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: programmingkidx at gmail dot com
Target Milestone: ---
Mac OS includes over 200 options for what std::locale can be set to. To view
this entire list run the command 'locale -a'. std::locale should be able to use
most or all of these locales. With g++ 14.2.0 std::locale fails most of the
time. Only the C and POSIX locales work.
This is the program used to set each locale. To build it run 'g++ main.cpp -o
program'.
To run this program on Mac OS use this command: 'locale -a | ./program'
#include <iostream>
#include <locale>
#include <stdexcept>
using namespace std;
int main() {
string line, name;
int i = 1, failures = 0, successes = 0;
// Read each line from standard input until EOF
while (getline(std::cin, line)) {
try {
name = line;
cout << "Setting locale to " << name << " ";
cout.imbue(locale(name));
cout << fixed <<123456.789<< endl;
successes++;
}
catch(exception &e) {
cout << "Failed" << endl;
failures++;
}
}
cout << "Number of failures: " << failures << endl;
cout << "Number of successes: " << successes << endl;
return 0;
}
Using g++ 14.2.0 I see these results:
Number of failures: 201
Number of successes: 2
Using clang++ 13 and 19 I see these results:
Number of failures: 1
Number of successes: 202
g++ info:
Using built-in specs.
