I'm running V 1.0.4 on Windows and IMSL_CONSTANT is failing with
% IMSL_CONSTANT: UDUNITS: failed to load the default unit database
Am I missing a file or do require additional configuration?

I have no MSwin around ... On my laptop running Linux and GDL compiled with udunits, I have :

GDL> gdl_status
% Compiled module: GDL_STATUS.
...
21 UDUNITS  :        1

and

GDL> imsl_constant('amu')
   1.6605387E-27

(could you check the GDL_STATUS ?)

You could try to compile GDL in WSL2, it should works fine, I already did that for colleagues months ago

In fact I llok at the build_gdl.sh script and udunits is here for MSwin

Could you also give a more detailed example ?

OK. I suspect you a problem with the related DLL, but I am totally ignorant with MSwin

Did you run the test suite ? May help to clarify what happen ?

GDL> print,IMSL_CONSTANT('C')

Did you install gdl from the installer, or did you compile it? In the first case, it would mean that a needed dll is missing from the installer? (not on MSWin, not even sure that such thing as an udunits.dll exists)

The error is issued from GDL code if UDUNITS XML files cannot be located:

gdl/src/gsl_fun.cpp

Lines 2881 to 2882 in 8157c12

    
           static ut_system* unitsys = ut_read_xml(NULL); 
        
           if (unitsys == NULL) e->Throw("UDUNITS: failed to load the default unit database");

So, likely it is not a DLL problem but an incomplete UDUNITS installation that shipped the DLLs, but not the XML files, or some other config issue that prevents UDUNITS from finding the XML files (see https://docs.unidata.ucar.edu/udunits/current/#Database).

That sounds right. I don’t see the XML file(s).

does that means we have to improve the tests or the message ?

(and yes, we still need a FAQ ! in the Wiki ?)

I believe the message is correct as it refers to a missing default database which is presumably missing XML file(s). I tried taking XML files from the UDUNITS distribution and place in a GDL path but was not successful. Do we know the expected XML file and location?

FWIW, here are the locations used in the Debian package: https://packages.debian.org/sid/all/libudunits2-data/filelist

Indeed, there is no way for us to check if a particular installation of a needed library contains all the required ancillary files. Even using the compile-all "build_gdl.sh" procedure, these ancillary files may be contained in other packages (debian for example is known to separate things in small independent packages, knowing that their database keeps the relationship) .
This goes for plplot, that has a dozen of ancillary files not necessary installe with the 'base' package, the proj library, and probably others.

@GillesDuvert @pjb7687 would this imply that we are not shipping the XML files together with the GDL Windows installer?

GillesDuvert Jan 18, 2024
Maintainer

of course! As I said, it needs user returns, such as this one, to figure out what is missing in a particular distribution.
One could be confident that everything works with a gdl compiled and installed using 'build_gdl.sh', because of the test file 'test_constants' working on the windows continuous integration machine, but for the Apple or Windows installer, the files need to be written in the installer package by the "build_gdl.sh pack" command. Obviously these XML files are absent and need to be added.

I wanted to let all know that I can resolve this issue on Windows if following a Windows installation of v1.04: 1. Copy the UDUNITS*.XML files from the UDUNITS installation zip to a directory 2. Set an environment variable UDUNITS2_XML_PATH to the full path (directory+name) of the udunits2.xml file

Not clear where to find those XML files.
It is said "This location varies depending upon your operating system and UDUnits2 compilation settings."

I am not building the DLL - but I downloaded the .zip distribution file - https://downloads.unidata.ucar.edu/udunits/2.2.28/udunits-2.2.28.zip There is a udunits2.xml file in the lib directory of the distribution which shows dependencies on other udunit*.xml files.
