new and delete

[boost lexical cast]

This works when I compile with g++ with -std=c++11.

int main()
{
    int *pointer = new int;
    delete pointer;

    return 0;
}

But, when I compile with -std=c++14 it does not.

Compile error:

/data/user/0/com.n0n3m4.droidc/files/gcc/tmpdir/ccVlJIIr.o: In function `main':
temp.c:(.text.startup+0x18): undefined reference to `operator delete(void*, unsigned int)'
collect2: error: ld returned 1 exit status

It does work when I do this, though.

int main()
{
    int *pointer = new int;
    delete[] pointer;

    return 0;
}

Why?

on cpp.sh it works on both versions...

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

// operator delete[] example #include <iostream> // std::cout struct MyClass { MyClass() {std::cout <<"MyClass constructed\n";} ~MyClass() {std::cout <<"MyClass destroyed\n";} }; int main () { MyClass * pt; pt = new MyClass[3]; delete[] pt; return 0; }

c++ 11 and c++ 14 MyClass constructed MyClass constructed MyClass constructed MyClass destroyed MyClass destroyed MyClass destroyed

what compiler are you using? isn't cpp.sh a good compiler?

[boost lexical cast]

I'm using gnu gcc compiler.

Your snippets compile fine for me using either switch using g++ 6.1.0.

[boost lexical cast]

They both compile fine when you're using -std=c++14? Hmmm, not for me.

How exactly are you compiling the program?

Can you post the build log when you compile the program?

Also your file extension indicates a C file not a C++ file try renaming your file to temp.cpp.
