The default locale from the users's environment is used (determined the environment variable LANG on Linux). But that does not work with the current libstdc++ implementation. The value of LANG is ignored and the name of Locale1 in the program tgl is set to the empty string which is wrong. Explicitly importing the German locale as in Locale2 works though. >How-To-Repeat: Source code tgl.C #include <iostream> #include <locale> using namespace std; int main() { locale Locale1(""); cout.imbue(Locale1); cout << Locale1.name() << endl; locale Locale2("de_DE"); cout.imbue(Locale2); cout << Locale2.name() << endl; } Compiling tgl.C g++ -v -o tgl tgl.C -W -Wall Reading specs from /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/specs Configured with: ../gcc/configure --enable-shared --disable-nls --enable-threads=posix --enable-clocale=gnu --enable-languages=c,c++,f77,objc Thread model: posix gcc version 3.1 20010710 (experimental) /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/cc1plus -v -D__GNUC__=3 -D__GNUC_MINOR__=1 -D__GNUC_PATCHLEVEL__=0 -D__ELF__ -Dunix -Dlinux -D__ELF__ -D__unix__ -D__linux__ -D__unix -D__linux -Asystem=posix -D__NO_INLINE__ -D__STDC_HOSTED__=1 -W -Wall -D_GNU_SOURCE -Acpu=i386 -Amachine=i386 -Di386 -D__i386 -D__i386__ -D__tune_i686__ -D__tune_pentiumpro__ tgl.C -D__GNUG__=3 -D__DEPRECATED -D__EXCEPTIONS -D__GXX_ABI_VERSION=100 -quiet -dumpbase tgl.C -W -Wall -version -o /tmp/ccMPOA3S.s GNU CPP version 3.1 20010710 (experimental) (cpplib) (i386 Linux/ELF) GNU C++ version 3.1 20010710 (experimental) (i686-pc-linux-gnu) compiled by GNU C version 3.1 20010710 (experimental). ignoring nonexistent directory "/usr/local/i686-pc-linux-gnu/include" #include "..." search starts here: #include <...> search starts here: /usr/local/include/g++-v3 /usr/local/include/g++-v3/i686-pc-linux-gnu /usr/local/include/g++-v3/backward /usr/local/include /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/include /usr/include End of search list. /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/../../../../i686-pc-linux-gnu/bin/as -V -Qy -o /tmp/cc7kLbiW.o /tmp/ccMPOA3S.s GNU assembler version 2.11.90.0.23 (i686-pc-linux-gnu) using BFD version 2.11.90.0.23 /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/collect2 -m elf_i386 -dynamic-linker /lib/ld-linux.so.2 -o tgl /usr/lib/crt1.o /usr/lib/crti.o /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/crtbegin.o -L/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1 -L/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/../../../../i686-pc-linux-gnu/lib -L/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/../../.. /tmp/cc7kLbiW.o -lstdc++ -lm -lgcc_s -lgcc -lc -lgcc_s -lgcc /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/crtend.o /usr/lib/crtn.o Running tgl LANG=de_DE ./tgl de_DE >Fix: >Release-Note: >Audit-Trail: >Unformatted:
