java - Extern "C" giving error "Linkage specification is not allowed" even after adding def. in header file? -

this code in main.cpp file:

extern "c" jniexport jint jnicall java_somefnhandling_jni_1someinit (jnienv * env, jobject , jstring var1, jstring var2) {     //rest part of code in here } 

this definition in main.h file:

#ifdef __cplusplus extern "c" {     #endif     jniexport jint jnicall java_someufnhandling_jni_1someinit         (jnienv *, jobject, jstring, jstring);      #ifdef __cplusplus } #endif 

this program taking 2 parameters java file , passing dll using jni interface in file i'm getting error:

linkage specification not allowed

i'm using vc++ generate dll file , have tried find same solution mentioning add def. in header file. after doing error still remains same. idea?

i removed method calling in main function , put outside of main , started working charm
