how to save map using ros

[DavidePatria]

using openvslam stand-alone it is possible to save the generated map in a specific location by simply using --map-db /path/to/map , but when using ros the option isn't accepted and ros returns an error.
The thing is that the localization mode still needs a map file, which is provided in the same way.
So, since the file apparently cannot be generated (or found, simply) using ros, does it have to be built using the standalone version?
If so, how does one use a rgbd camera for the job?

Please describe the command and error details. The option exists,

so if it doesn't work, it's a bug.

If you want to run it in the standalone version, see below.

However, I think it is easier to load from bag.

I don't know what had happened, but today the maps are correctly saved.
