Question

Family : ARM

Varient : Tiva TM4C123GH6PM

When try to build c++ class in main.c It is giving below error

class details are :

main.c

#include "Generic.h"

int main(void) {

    Generic *generic;
    return 0;
}

Generic.cpp

#include "Generic.h"

Generic::Generic() {
    // TODO Auto-generated constructor stub

}

Generic::~Generic() {
    // TODO Auto-generated destructor stub
}

Generic.h

#ifndef GENERIC_H_
#define GENERIC_H_

class Generic {
public:
    Generic();
    virtual ~Generic();
};

#endif /* GENERIC_H_ */

I am not sure whether we need to make main.c to main.cpp. If that is so then which make file need to updated for main.cpp

Any help on c++ compilation for ARM

`armcl` seems to have a `--cpp_default` command line option, you could try that if you absolutely cannot rename your main.c — Karsten Koop, May 31 '16 at 07:22

From TI forum :

By default the TI ARM compiler uses the file extension to determine if to compiler a source code as C or C++. If this is a CCS project, you can just rename main.c to main.cpp and the CCS generated makefile will be updated automatically.

This works now. Thanks.
