No .debug_str found in ELF file?

Im doing a project that works with ELF files. Right now Im using the following as a sample input - 

class C {
public:
    C();
    C(int x, int y);
    int getX();
private:
    int x;
    int y;
};

class SubC : public C {
    int z;
};

int f() {return 0;}

C c;
SubC subC;

int i;
double d;

I then run

gcc test.cpp -g -c -o test.o

and I get test.o as expected. I then feed test.o into a library I found called peter-dwarf. My problem is that the library says "no section .debug_str found in test.o"

Am I doing something wrong during compilation? Or is the library not working?

Edit: should have been a -g in there

Use -g in gcc to generate the debug symbols. You may also refer to the documentation of debugging options of gcc here.

The -g alone might not include DWARF information if your system is configured in some way. There is a number of switches related to DWARF specifically, so if -g alone does not work, you may need to go there and mangle with other switches.

Probably you need to compile with debugging information enabled. Try:

gcc -g test.cpp -c -o test.o
