Can't start gdb over ssh

I am able to open a remote C source file using tramp (via ssh). However, when I try to debug it using

M-x gdb gdb -i=mi /ssh:localhost#8022:/usr/bin/httrack 

I get

Current directory is /ssh:localhost#8022:/usr/bin/ Error: you did not specify -i Debugger exited abnormally with code 127
