v.krige won't load: ImportError: No module named globalvar

[momsen]

Hello, I have installed GRASS 7 this week, along with gdal/geos/spgrass6/etc. I'm on a Debian system. R and many of the dependencies came from Debian packages. But gdal and GRASS I installed from source.

v.krige gives the following errors. R/spgrass6 does work, I used readVECT6 and readRAST6 to load data into R.

Is there something else I should install/change on my side, or is this a bug?

I tried loading the R package dependencies I knew about in R, that seemed to be a common theme in previous v.krige errors. I think I have everything installed.

Hello momsen,

thanks for the well detailed report.

v.krige is not aware of last GUI reorganisations, so it can't load properly, as stated by the traceback:

ImportError?: No module named globalvar

So far I didn't find the time to update the module. If you are willing to help, let me know.

Moreover, the module should not require zoo and xts packages. I can't see them as dependencies of the modules needed by v.krige, that are:

rgeos, gstat, spgrass6, maptools

Can you load these packages in a R session?

Thanks for the feedback, Anne

[momsen]

It is nice to hear I've finally gotten to the point where my installation wasn't at fault. I have not yet updated/written code for any open source projects, but want to learn. I have a presentation Tuesday, so if someone can provide guidance I could look at it then. If you find time to make the update before that, I'm sure there will be other things I can help with later.

I'm late for leaving for the weekend, I'll be able to check more on zoo and xts later. Both can be loaded directly in R as well, from memory zoo was a dependency for one of the spgrass6 related packages. At least it shows up each time I installed it!

[momsen]

I am able to load rgeos, gstat, spgrass6, and maptools in a R session.

I found where zoo and xts came from:

automap is optional (provides automatic variogram fit) for v.krige. automap depends on gstat, which depends on spacetime, which depends on zoo and xts.

-Eric

Startup problems fixed in r53127.

Remaining issue: creating the variogram leads to

I can fix the FlatNotebook? part of error (probably tomorrow, I must first download some packages to be able to test it).

Replying to annakrat:

I can fix the FlatNotebook? part of error (probably tomorrow, I must first download some packages to be able to test it).

After installation of needed packages I get this error:

I have no idea what rx is or how too fix this.

[annakrat]

The problem with notebook should be fixed in r53148. Anna

[neteler]

One more fix done in r53149.

[neteler]

For now v.krige is commented out in the parent Makefile, see r53194.
