[GRASS-stats] error when trying to start GRASS from Rstudio in Windows

[Veronica Andreo]

Hi

I taught a GRASS course last week and all students got the same error when
trying to init GRASS from R or Rstudio (in all cases grass was installed
through OSGeo4W installer).

HereÂŽs the command we used (paths must be adapted accordingly):

initGRASS(gisBase = "C:/OSGeo4W64/apps/grass/grass-7.4.2RC2",
gisDbase = "C:/Users/RETA/Documents/grassdata",
location = "nc_spm_08_grass7",
mapset = "user1",
SG = "elevation")

The pop-up error is a missing iconv.dll. See screenshot attached. I believe
all locales were in Spanish as well as the laptop I am testing now. After
many attempts to try to close the pop-up error, we got the following in the
Rstudio console:

Error in if (!compatible) { : argument is of length zeroIn addition:
Warning messages:1: In system(paste("g.dirseps.exe -g",
shQuote(Sys.getenv("GISRC"))), : running command 'g.dirseps.exe -g
"junk"' had status 3092: In system(paste("g.dirseps.exe -g",
shQuote(gisDbase)), intern = TRUE) : running command 'g.dirseps.exe
-g "C:/Users/RETA/Documents/grassdata"' had status 3093: In
dir.create(loc_path) : cannot create dir 'NA\nc_spm_08_grass7',
reason 'No such file or directory'4: In dir.create(paste(loc_path,
"PERMANENT", sep = "/")) : cannot create dir
'NA\nc_spm_08_grass7\PERMANENT', reason 'No such file or directory'5:
In dir.create(paste(loc_path, mapset, sep = "/")) : cannot create dir
'NA\nc_spm_08_grass7\user1', reason 'No such file or directory'6: In
system(paste("g.version", get("addEXE", envir = .GRASS_CACHE), :
running command 'g.version.exe' had status 309

Is this grass or windows problem? I did not get this error in this same
laptop a month ago when Roger fixed some other problems. Seems that
something changed meanwhile.

Cheers,
Vero

Hi Vero;I got the same error a while back and I ended up finding a workaround by copying all of the .dll files from C:\OSGeo4W64\bin to C:\OSGeo4W64\apps\grass\grass-7.4.1\bin. I have grass installed on my C drive but follow the path to your installation path bin. It appears that the .dlls are different or incompatible.

yes, it is a dll mismatch. please report this in the GRASS ML, or better
open a ticket about this in the bugtracker

As far as I seee the a iconv.dll-issue (missing iconv.dll) is not yet
mentioned in the ticket.
More details on that might be useful.

In the body of the ticket I mentioned that the "pop-up error is a missing
iconv.dll" and I also linked this email thread... how to re-remark that or
make it clearer?

In the body of the ticket I mentioned that the "pop-up error is a missing iconv.dll" and

Yes - but the real error message might help.

see https://lists.osgeo.org/pipermail/grass-dev/2018-November/090433.html
for the solution:

"starting R/RGUi/RStudio from the OSGeo4W-console, then it works."

tested here now with

-----------------

confirmed, also here a iconv.dll-issue (missing iconv.dll); and also
confirmed that it worked a month or so ago.

closer look at the error message and the used dependencies:

winGRASS 7.4.2 is now compiled against GDAL: 2.3.2 and PROJ.4: 5.2.0

when I tried a month or so ago, winGRASS was compiled against GDAL 2.0.X (or
similar) and PROJ.4 4.9. (or similar).

it seems there could be a dll mismatch between old and new dependencies
versions; hence the iconv.dll issue.
