Compile with -g option but "Single stepping until exit from function main, which has no line number information"
c++, debugging, gdb, ubuntu
Solution
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.
Problem
I have some trouble with gdb. This is my code in a single file named main.cpp ``` #include <iostream> void myfunc(); int main(){ char msg[] = "Hello World!"; myfunc(); std::cout << msg << std::endl; return 0; } void myfunc(){ int boo = 16; } ``` I used this command to compile this code : ``` g++ -g -Wall main.cpp -o foo ``` Next, I used gdb : ``` $ gdb foo (gdb) start Temporary breakpoint 1 at 0x80487c3 Starting program: /home/laptop/workspace/foo Temporary breakpoint 1, 0x080487c3 in main () (gdb) s Single stepping until exit from function main, which has no line number information. Hello World! __libc_start_main (main=0x80487c0 <main>, argc=1, ubp_av=0xbffff3a4, init=0x80488b0 <__libc_csu_init>, fini=0x8048920 <__libc_csu_fini>, rtld_fini=0xb7fed280 <_dl_fini>, stack_end=0xbffff39c) at libc-start.c:258 258 libc-start.c: No such file or directory. ``` What did I do wrong ? I use the -g option but I still got this error. Configuration : - GDB : GNU gdb (Ubuntu/Linaro 7.4-2012.04-0ubuntu2.1) 7.4-2012.04 - GCC : g++ (Ubuntu 4.8.1-2ubuntu1~12.04) 4.8.1 I installed these tools with a classic : sudo apt-get install Thank you by advance for any answer :-)
