I'm trying to use the C# gdal bindings but I get an error in my C# code which says "Unable to load DLL 'gdal_wrap': The specified module could not be found. (Exception from HRESULT: 0x8007007E)".

I've had a look at the dependencies for gdal_csharp.dll and everything looks okay. Two things that stood out though were that the csharp dll is a 32 bit dll, while all the dependencies are for a 64 bit system (my machine has a 64 bit CPU). Also, the file ieshims.dll was listed as a dependency, but from what I gather, it isn't strictly necessary that it be installed.

I've tried installing the files manually via a zip file and also using the .msi installer for the gdal core libraries. I made sure to add the paths to the gdal executables to my system path.

I downloaded the binaries from here: http://www.gisinternals.com/query.html?content=filelist&file=release-1800-x64-gdal-1-11-1-mapserver-6-4-1.zip

And I roughly followed this guide for installation instructions: http://vipassanaandenvironmentalinformatics.blogspot.co.nz/2013/03/getting-started-with-c-and-gdal.html

I'm using Visual Studio 2013, for which the binaries are available on the site above.

  • Thanks for posting that question, I put the gdal_wrap.dll into dependency walker and it turns out that there is a missing dependency called gdal111.dll, I'll try to track this down and post an update on my progress.

  • @StealthRabbi I ended up using the gdal command line tools via OSGEO4W and C# code. It was much easier to set up this way. But of course you don't get all the benefits of using the C# gdal libraries.

    Don't know if you ever solved this, but this turned up for me trying to solve the same issue, and I ended up adding an answer to the SO question link in comment number one which solved the issue. If it helps I'll happily post it as a question on this question too. SO-GIS seems a more appropriate place anyway.

Get the package from NuGet and then you need to call static methodGdalConfiguration.ConfigureGdal() from GdalConfiguration.cs/vb at startup to set process environmental variables. Call GdalConfiguration.ConfigureOgr() if you want to use OGR as well.
