So i defined a wrapper of gdb from docker: ---------------------------------8<------------------------------------- #!/bin/sh arg="$@" docker exec -i myproject gdb -i=mi ${arg} ---------------------------------8<------------------------------------- Then invoke the gdb with: (gdb "/path/gdbWrapper"). The *gud* buffer can be created successfully. The executable file can be loaded OK, however, it reports some tty error while trying to run the executable: ---------------------------------8<------------------------------------- (gdb) file a.out Load new symbol table from "a.out"? (y or n) [answered Y; input not from terminal] Reading symbols from a.out...done. (gdb) r Starting program: /test/a.out /dev/ttys002: No such file or directory. During startup program exited with code 1. (gdb) ---------------------------------8<------------------------------------- If I run the gdbWrapper directly from a terminal application, everything is fine, i don't see the same error there. What could be wrong in the gdb mode? -- William
