You may like to check which symbols bound to which libraries by using
LD_DEBUG environment variable. The following example runs on Linux,
you may need to check Solaris ld.so man page:
[EMAIL PROTECTED] test]$ cat test.cc
#include <iostream>
int main() { std::cout << "hi\n"; }
[EMAIL PROTECTED] test]$ g++ -Wall -o test test.cc
[EMAIL PROTECTED] test]$ ./test
hi
[EMAIL PROTECTED] test]$ LD_DEBUG=bindings ./test 2>&1 | c++filt | grep cout
10314: binding file /usr/lib/libstdc++.so.6 [0] to /usr/lib/
libstdc++.so.6 [0]: normal symbol `std::wcout' [GLIBCXX_3.4]
10314: binding file /usr/lib/libstdc++.so.6 [0] to ./test [0]:
normal symbol `std::cout' [GLIBCXX_3.4]
10314: binding file ./test [0] to /usr/lib/libstdc++.so.6 [0]:
