Compile with -g option but “Single stepping until exit from function main, which has no line number information”

Question

I have some trouble with gdb. This is my code in a single file named main.cpp

#include 

void myfunc();

int main(){
    char msg[] = \"Hello         


        

Answer 1

Try to use '-Og', too. Maybe that will help, because as @KevinDTimm wrote: compiler may optimize it.

Reference:

• "c++ --help=optimizers"

Answer 2

Compile using -g and -ggdb flags.

Your command should be

g++ -g -ggdb -Wall main.cpp -o foo

Answer 3

Thank you for your answers. I found what is wrong. As jcm says my gcc is relatively new. I have update gdb to the last current version which is GNU gdb (GDB) 7.6. Now this works perfectly.

By the way, with the version g++ (Ubuntu/Linaro 4.6.4-1ubuntu1~12.04) 4.6.4, gdb (Ubuntu/Linaro 7.4-2012.04-0ubuntu2.1) 7.4-2012.04 works perfectly.

Thank you for all of you.
