I looked further and I am thinking that perhaps it is the fault in the<br>
naming of the rangs and gshhs files,<br>
in particular the parentheses "(" which is a special character and I think<br>
Ubuntu has trouble with.<br>
<br>
I have successfully run the script in:<br>
Distributor ID: RedHatEnterpriseServer<br>
Description: Red Hat Enterprise Linux Server release 6.9 (Santiago)<br>
Release: 6.9<br>
Codename: Santiago<br>
<br>
I get the segmentation error when running in Ubuntu:<br>
Distributor ID: Ubuntu<br>
Description: Ubuntu 18.04.2 LTS<br>
Release: 18.04<br>
Codename: bionic<br>
<br>
the rangs directory looks like this:<br>
-rw-r--r-- 1 root root 89496428 Μαΐ 13 1997 'gshhs(0).rim'<br>
-rw-r--r-- 1 root root 20775224 Μαΐ 13 1997 'gshhs(1).rim'<br>

-rw-r--r-- 1 root root 3045848 Μαρ 19 16:48 'rangs(4).cel'<br>
<br>
The single quotes in the filenames come automatically (for Ubuntu to be able<br>
to handle them) when I download them.<br>
<br>
I know that NCL is looking for this file because when I have HighRes and<br>
when I deliberately export NCARG_RANGS to a different directory, I get<br>
fatal:MapRGDHDrawMapList: MDRGOL/MDRGOF - ERROR OPENING RANGS/GSHHS CAT.<br>
When I export NCARG_RANGS= /usr/share/ncarg/database/rangs I get the<br>
segmentation fault.<br>
<br>
Is it an environment thing? Is it Is it a permission thing? I tried running<br>
with sudo to no avail. I don't know how NCL "reads" these files. Final note,<br>
<br>
Using ls I get:<br>
ls gshhs(0).rim<br>
bash: syntax error near unexpected token `('<br>
with quotes:<br>
ls 'gshhs(0).rim'<br>
'gshhs(0).rim'<br>
<br>
Thanks again for your time,<br>

Subject: Segmentation fault (core dumped) when mpDataBaseVersion =<br>
"HighRes", new NCL build on Ubuntu<br>
<br>
<br>
<br>
Deal all,<br>
<br>
I just installed NCL 6.4.0 through the Ubuntu Software in my desktop within<br>
an Ubuntu virtual machine with 5GB of RAM.<br>
I am trying to run a script (which runs successfully on a 4gb laptop, with a<br>
virtual machine of 2GB of RAM) but I get a Segmentation fault (core<br>
dumped).<br>
When I use mpDataBaseVersion = "LowRes" it works fine, although no colors<br>
appear on my contour plot (the label bar has colours just fine).<br>
<br>
Is it possible that I run out of memory for some reason? I am suspicious of<br>
the new build. I followed the rangs procedure for high resolution<br>
coastlines. I do not know if it's important but the NCARG_ROOT is not set as<br>
in the default that I find in the NCL site. My suspicion increases due to<br>
the lack of colour in the contour (I'm using<br>
gsn_define_colormap(wks,"gui_default")).<br>
<br>
<br>
In my script I load:<br>
load "/usr/share/ncarg/nclscripts/csm/gsn_code.ncl"<br>
load "/usr/share/ncarg/nclscripts/csm/gsn_csm.ncl"<br>
load "/usr/share/ncarg/nclscripts/csm/contributed.ncl"<br>
load "./shapefile_utils.ncl" ; This I need for shapefiles<br>
<br>
I found a relative thread in the ncl-archive under "[ncl-talk]<br>
mpDataBaseVersion ="HighRes" " but there was no solution therein.<br>
<br>
Cheers and thanks for your time,<br>
<br>
