Conditions under which stepping into shared library should work in gdb?

Question

There are many questions related to specific errors why stepping into a shared library with gdb isn\'t working. None of them provide a systematic answer on how to confirm wh

Answer 1

GDB 7.11 can't reproduce this problem. This is my steps. I hope this will help you:

1.gcc -ggdb -c -Wall -Werror -fpic myshared.c -o myshared-ggdb.o
2.gcc -ggdb -shared -o libmyshared-ggdb.so myshared-ggdb.o
3.gcc -ggdb main.c -lmyshared-ggdb -o app-ggdb -L.
4.gdb ./app-ggdb

In GDB,

(gdb) set env LD_LIBRARY_PATH=.
(gdb) b main.c:7
Breakpoint 1 at 0x4006a5: file main.c, line 7.
(gdb) r
Starting program: /home/haolee/tmp/app-ggdb 

Breakpoint 1, main () at main.c:7
7       print_from_lib();
(gdb) s
print_from_lib () at myshared.c:5
5       printf("Printed from shared library\n");
(gdb) 

I step into the function print_from_lib successfully.
