If you run "gdb vmlinux", does it find it? For example:
(gdb) ptype union thread_union
Python Exception <type 'exceptions.ImportError'> No module named
gdb.types:
type = union thread_union {
struct task_struct task;
unsigned long stack[2048];
}
(gdb)
BTW, the snippet above is using gdb-7.6, and Fedora's 4.16.0-300.fc28.x86_64
vmlinux kernel that was built yesterday.
