Using xilkernel with C++

Hi,
is there a way to get the Xilkernel to run with a C++ application? I
didn't find any option for this in the XPS "Software Platform
Settings".
The problem I'm having is that my thread function ("TSK_Main", which
is declared in the C++ application) cannot be called from libxil.a,
which is a C library. This is the error message that I'm getting while
trying to build the C++ application:
../../ppc405_0_sw_platform/ppc405_0/lib/libxil.a(init.o):(.sdata+0x0):
undefined reference to `TSK_Main'
Maybe someone knows a workaround for this?
Many thanks,
Guy.

This seems to be a linker problem. The naming conventions for c and c++
object files are different. You can declare C function in C++ with:

extern "C" {
  ... TSK_Main(...);
}

or vice versa

extern "C++" {
  ... TSK_Main(...);
}

Thanks, Markus.
It is indeed a linker issue, which was solved using extern "C". Still,
I'm wondering if there are any other issues when using xilkernel with C
++?
