Compilation of firefox extension with xulrunner-sdk-15.0.1 also later version

I have a FF toolbar working in all previous versions. My toolbar partially written in C++. I've tried to build the C++ part with xulrunner-sdk-15.0.1 (I tried also xulrunner-sdk-16.0.1) In both versions I receive a link error.

Has somebody idea how it can be solved?

These symbols are exposed by msvcrt.lib (runtime library). So you probably configured the project to ignore standard libraries - you need to add msvcrt.lib to the list of libraries explicitly then.

Just in case you don't know: js-ctypes allow you to have compiled code in your extension without having to use binary XPCOM components and recompiling them for each Firefox version. You can include a regular Windows DLL in your extension and use js-ctypes to call its functions. The drawback: this DLL won't have access to XPCOM. So if you really need low-level XPCOM access that JavaScript doesn't have then you cannot avoid binary XPCOM objects.
