missing gdal111.dll and broken page for downloading about taudem

[kornholi]

This link should work for GDAL: http://download.gisinternals.com/sdk/downloads/release-1600-x64-gdal-1-11-3-mapserver-6-4-2/gdal-111-1600-x64-core.msi

Just tried it, and it's still telling me it can't find the file.

[pkdash]

These 2 links should work:
win64: http://download.gisinternals.com/sdk/downloads/release-1600-x64-gdal-1-11-0-mapserver-6-4-1/gdal-111-1600-x64-core.msi
win32: http://download.gisinternals.com/sdk/downloads/release-1600-gdal-1-11-0-mapserver-6-4-1/gdal-111-1600-core.msi

[LaraU]

Tried all of those, and I'm still getting the error.

[pkdash]

What browser are you using?

[LaraU]

Internet explorer or Chrome. I should clarify - the links you provided work, but I'm still getting the same error message when I try to run a tool.

[pkdash]

I am able to download using both of the links in Firefox as well MS Edge.

[pkdash]

Got it. I am looking into the tool error still.

[LaraU]

Many thanks!

Do you see anything related to gdal in the list of installed programs? Is your OS win32 or 64?

[LaraU]

Yes. It shows up in my programs. I have Win64.

C:\Program Files\GDAL

[LaraU]

It's funny - the gdal111.dll is in the GDAL folder, but it seems as if the PitRemove tool can't find it when I try to run it.

[pkdash]

Do you see 'GDAL 111 (MSVC 2010 Win64)" listed in the list of installed programs?

[pkdash]

Also check if windows path includes C:\Program Files\GDAL

[LaraU]

Yes to both questions. The program is installed, and the path is there.

Can you see if TauDEM runs from a command prompt. At a command prompt type
mpiexec -n 2 pitremove elev.tif
where elev.tif is the name of your input file. If this works then we look into something associated with the ArcGIS environment. If you get the same error then we continue to look into path issues. What is the result if you type
where gdal111.dll at a command prompt
If paths are right you should get C:\Program Files\GDAL response.

[LaraU]

It seems to run with a command prompt.

When typing the where gdal111.dll it tells me that it could not find the files for the given pattern(s). But I know the files are there.

[dtarb]

That is a bit mysterious. I would have expected it to either run and find gdal111.dll or not run and not find it together, but not one and not the other.

My next hunch is that your system path is not working right. Perhaps it is too long or corrupted by an incorrect character. I suggest at the command prompt type
path
to see what your path is
path > mypath.txt
to save a copy of what your path is to the mypath.txt file
Then you can follow steps on page 3 in http://hydrology.usu.edu/taudem/taudem5/TauDEM5CommandLineGuide.pdf which is an older help document from TauDEM if you see anything missing that needs editing. If you can remove (perhaps temporarily) entries that are not necessary, or place c:\Program Files\GDAL close to the beginning it may help. In editing your path you need to be very careful though, as things like stray spaces can corrupt entries and stop other programs from working which is why a copy to a file is important. Note that each time you save a path you need to restart any programs that you want to use the new path, i.e. close and re-open the command prompt and ArcGIS.

[LaraU]

Ok - I'm looking at my path info, and it seems as if it might be in there twice and it's getting confused. I am not a programmer, so forgive me if this is a dumb question, but could you tell me which is the correct path? I see the C:\Program Files\GDAL (which I moved to the front) and C:\GDAL. Are they both supposed to be there? Thanks again.

[LaraU]

Never mind - success with moving the path to the beginning! Thanks so much!!

[dtarb]

Both are needed. One is GDAL libraries used by Python and the other GDAL applications. If you need to know @pkdash could explain what TauDEM uses from each. I am glad it is working. Keep a close eye on your system though to be on the lookout for other things that may have been impacted by the path change.
