Trouble in Adding cpp header in C file.

Trouble in adding, cpp header in c file.

Hi,

I am facing trouble in adding CPP header in C file.

I have main.c, of native NDK, was trying to

call cpp functions from this main.c, but while

adding cpp header on to c file its throwing error. 

Error :

jni/main.c:35: error: expected identifier or '(' before string constant

jni/main.c: In function 'android_main':

My main.c file has : 

/*c_file.h*/

#ifndef __cplusplus

extern "C++" {              /*Line 35: Getting error at this line */

#endif

//#include "cpp_file.h"  /*My CPP header file*/

#include "libcam.h"

#ifndef __cplusplus

} 

Any pointer will help

 

Thanks,

C++ and C are different languages.

You need "#ifdef __cplusplus" (not ifndef) so that the extern C++ line
is only compiled in C++ mode.

Best regards.

It needs to be 'extern "C"' too. There exists no "extern C++" for C.
