C++라이브러리를 C app에서 사용하기

--- library program (C++ source) testCpp.cpp -------

#include "cstdlib.h"
#include "iostream.h"
#include "stdio.h"
#include "errno.h"
#include "stdlib.h"
 
extern "C"
int lib_program(char * szProgMode , char * filename)
{
	printf("TestApp \n");
	return 0;
}

--- test program (C source) testCppApp.c ------

#include "stdlib.h"
#include "stdio.h"
 
int main(int argc, char *argv[]) {
	int res = 0;
 
	printf("call library function\n");
	res = lib_program(argv[1], argv[2]);
 
	return res;
}

물론 library에는 다른 C++ code들이 많이 있습니다.
실제로 call이 되어지는 library의 function만 발췌한 것입니다.

gcc -o ./testCppApp ./testCppApp.c ./libtestCpp.a
이와 같이 하면

와 같은 error가 발생합니다.

가르침을 주시기 바랍니다~ ^^
