$ cat test.cpp
#include <locale>
typedef char (std::moneypunct_byname<char,false>::*mbr)() const;
void g(mbr x);
int main() {
g(&std::moneypunct_byname<char,false>::decimal_point);
}
$ cat test2.cpp
#include <locale>
typedef char (std::moneypunct_byname<char,false>::*mbr)() const;
void g(mbr x) {
}
$ clang++ -o test.so -shared -fPIC test.cpp test2.cpp
Undefined symbols for architecture x86_64:
"std::__1::moneypunct<char, false>::decimal_point() const", referenced from:
_main in test-c3f9f0.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
This works with libstdc++.
