Getting undefined reference error from ZThread

Using MinGW 4.2.1, GCC 3.4.6.

ZThread compiles fine into a library but when i compile a class using it, I get the errors:

(ThreadLocalImpl.o):ThreadLocalImpl.cxx:(.text+0x8 c):
undefined reference to `std::_Rb_tree_rebalance_for_erase(std::_Rb_tree_n ode_base*, std::_Rb_tree_node_base&)'

undefined reference to `std::_Rb_tree_insert_and_rebalance(bool, std::_Rb_tree_node_base*, std::_Rb_tree_node_base*, std::_Rb_tree_node_base&)'

undefined reference to `std::_Rb_tree_decrement(std::_Rb_tree_node_base*) '

undefined reference to `std::_Rb_tree_decrement(std::_Rb_tree_node_base*) '

undefined reference to `std::_Rb_tree_increment(std::_Rb_tree_node_base*) '

undefined reference to `std::_Rb_tree_increment(std::_Rb_tree_node_base const*)'

Do you have any idea what might be causing these?

Thank you for any help you can give me,

You're not linking against the standard library, or against a wrong version.
Could be:
1) a badly set up IDE or compiler, not linking against the library
2) a badly set up IDE or compiler, using a different compiler's standard headers
3) a mismatch between the standard library this ZThread was compiled against and the one you're using now

Thanks.

Hmmm... I compiled ZThreads with the same compiler so i don't think that's the problem. What's weird is when I compiled zthreads I got no issue but when i try to compile something using it, I get an issue.

Well, the compiler messages suggest that you're compiling ZThreads as a static library, in which case there would be no linking stage. Since these are linking errors, they wouldn't be apparent during the library creation.

So, how about the compiler setup? Are you compiling on the command line or in an IDE? What is the exact command to the compiler?
