Hi,
I hope to use gdb to debug docker to learn the source code, but I found when I run gdb docker (the docker was compiled from source code on Ubuntu Wily), and tried to list the source code, it got the error message:
/tmp/go-build630010359/github.com/docker/docker/pkg/term/_obj/_cgo_export.c: No such file or directory.
If I edit the hack/make/binary and append -gcflags '-N -l' to the go build command, then the compiling was failed:
++ go build -o bundles/1.10.0-dev/binary/docker-1.10.0-dev -a -tags 'autogen netgo static_build sqlite_omit_load_extension apparmor seccomp selinux daemon journald btrfs_noversion libdm_no_deferred_remove' -installsuffix netgo -gcflags '-N -l' -ldflags '
-w
-extldflags "-static"

Makefile:68: recipe for target 'binary' failed
make: *** [binary] Error 1
What looks like it cannot fully support golang program.
My gdb version is 7.10, and the docker version I tried was 1.8, 1.9, 1.10-dev, all of them have the same issue.
Can anyone help on that? Thanks!
