Contents of test.cpp below
---------------------------------
#include<stdlib.h>
#include<string.h>
#ifdef __cplusplus
extern "C" {
#endif
#include "test.h"
#ifdef __cplusplus
}
#endif
int main(int argc, char **argv)
{
return 0;
}
----------------------------------
In test.cpp, i changed :
#include "test.h"
to this
extern "C" {
#include "test.h"
}
And the same compilation error mentioned below.

Could you list the contents of test.cpp
And I'm going to take a guess here. In test.cpp, can you change this:
#include "test.h"
to this
extern "C" {
#include "test.h"
}

Hi,
I have one c file , header file and one Makefile , and including ISC DHCP-4.2.3 libraries and header files in a Makefile.
For eg:
[amin at csc dhcpd_test]$ ls
Makefile test.c test.h
Contents inside c file and header file below.
------------------------------------
vi test.c
#include<stdlib.h>
#include<string.h>
#include "test.h"
int main(int argc, char **argv)
{
return 0;
}
-----------------------
vi test.h
#include<dhcpd.h>
--------------------------
vi Makefile
EXECUTABLE = dhcp-server
# Sources
C_SRCS := $(wildcard *.c)
.
.
.
.
.
.
.
.
-------------------------------
And I compiled,
[amin at csc dhcpd_test]$ make
----- Compiling test.c
test.c: In function `main':
test.c:17: warning: unused parameter `argc'
test.c:17: warning: unused parameter `argv'
----- Linking dhcp-server
[amin at csc dhcpd_test]$ ls
dhcp-server Makefile test.c test.h test.o
[amin at csc dhcpd_test]$
[its compiling successfully and create a executable called dhcp-server]
But,When I changed test.c to test.cpp and changing CXX_SRCS := $(wildcard *.cpp) in a Makefile
Its not compiling and throws compilation errors.
[amin at csc dhcpd_test]$ ls
dhcp-server Makefile test.cpp test.h

What would be the problem..
Please let me know.
But I actually need test.cpp and CXX_SRCS := $(wildcard *.cpp) to compile .
Thanks,
