Capture gdb output with ruby

Question

I tried to do that :

a = `gdb -q ./test` ; print a

But it's showing nothing, even the gdb process are running. How can I do it ?

Answer 1

gdb waits for some command after start entered from stdin. At least, r to run program. So you need to send r to gdb. Try this:

a = `echo 'r'|gdb -q ./test`; print a
