Unable to find or open the Digital Chart of the World

[niclasmattsson]

Does DCW need to be installed manually or should it be automatically included in GMT? I downloaded version 1.1.4 from the ftp site in the error message, but where should I put it? There doesn't seem to be a DIR_DCW folder anywhere.

The GMT installer should install everything so something funny is happening to your installation and not unlikely related to your other issue. The mentioned files are stores under gmt6\share\coast and gmt6\share\dcw directories. Please see what you have (the files themselves are netcdf (.nc) files).

[niclasmattsson]

The coast folder seems OK, but there is no dcw folder.

Ah, finally remember this. It's a dumb issue we have with our installer that insists in having the DCW install set to optional. Old bug still waiting for a solution. Till than, just make sure that you select the DCW option from within the installer.

[niclasmattsson]

OK. I know I set the option while installing a few times, but at this point I've uninstalled and reinstalled so many times that I may have missed to check that option above. Sorry about that. Anyway, it's working now with the new installer you linked in the other issue.

[joa-quim]

Yes, I know it's very easy to skip option and I want to get that fixed. I remember to tried it once but than it caused some other problem and I drop it.

[niclasmattsson]

By "it's working now" I meant that dcw-gmt.nc now actually gets installed into GMT6/share/dcw. But I still get the exact same error as in the first post above, even with the new installer. Does DCW need an environmental variable or something?

[joa-quim]

The installer declares only one env variable called GMT5_SHAREDIR. From memory I'm not sure if is used all the times or only when its need to find where the share directory is. Anyway, this variable is removed when one do uninstall. One possibility is if, by any reason, your installs and uninstalls left one behind pointing a wrong directory. Please check in your environmental variables that its pointing to the correct location.

As another test please run this on the command line (the dos cmd)

pscoast -EAR+p0.25p+gblue -Ba -JM10 -P > argentina.ps

It should create the (almost) same figure in postscript as the one we are trying to create with the Julia wrapper.

[niclasmattsson]

Same result.

OK, what is it different that you get when running this in the cmd shell?

[niclasmattsson]

The problem was the shared folder environment variable after all. It was missing before so I had to enter it from scratch. I must have been misled by the name GMT5_sharedir because I pointed it to gmt5/share instead of gmt6/share. I really need to stop trying to debug stuff after midnight ...

Now the pscoast command works perfectly in the CLI. Running coast() from Julia still doesn't work, probably because the tests still fail, see the other issue.

[joa-quim]

Yes, the GMT5_SHAREDIR env var may be missing (I think) but cannot be pointing to a false location.
