including c libs in c++ code?

Hi I am trying to compile a cpp ap that runs on the system tray and checks
recently open files with clamav. i am getting a whole bunch of undefined 
erros. can i link this library to a cpp program? do i need any special 
confiure options?. i tried removing pthread and other libraries and the 
results are similar. or should i write a small lib that checks buffers
and just use my lib with extern? thanks for the advice.

the code looks like this
extern "C" {
#include "clamav.h"

int cl_loaddbdir(const char *dirname, struct cl_node  **root, int *virnum);

}

compiled with 
redir -e out.txt g++ -o temp.exe myapp.cpp -mwindows -mno-cygwin -lclamav -
lz -lbz2 -lgmp

errors

More off-topic than talking about cooking meat on a vegetarian newsgroup.

Here's what you want:


News server:  msnews.microsoft.com
  Newsgroup:  microsoft.public.win32.programmer.kernel



Best of luck.
