[ECOS] Help! extern C linkage for thread entry functions

[Giri Raja <giri_amf at yahoo dot com>]

Hi, 

I'm working on the EB40A board and my application is
in C++. Mine is a multi file application and I use a
common header file and include it in all my cc files.
I do have a #ifndef ... #define directive in my header
file to avoid multiple declarations. 

But still when I try to make it all, I get multiple
reference errors. But if the application is in C, the
whole thing compiles and works fine. 

I kind of figured that it is somewhat related to
declaring the thread entry functions within the extern
C block. But I'm not sure. How do I declare the thread
entry functions in C++. i.e if my thread function is
"Read_FIFO"  can I say

extern "C"  {
	cyg_thread_entry_t Read_FIFO;
}

or extern "C"  {
	void Read_FIFO(cyg_addrword_t );
}

In the first case I'm getting the multiple definition
erros, and in the second case I'm getting a conflict
with the previous declaration of
cyg_thread_entry_t Read_FIFO.

Can someone please help me. Thanks in advance. 

Giri.
