Unable to load DLL 'libgdiplus': The specified module could not be found.

I can not use GDI+ related things on Fedora 30.
I am getting an error while calling Image.FromStream(ms).

Error & stacktrace:

System.TypeInitializationException : The type initializer for 'Gdip' threw an exception.

You can try

sudo apt install libc6-dev 
sudo apt install libgdiplus

or https://github.com/mono/libgdiplus

Looks answered. Feel free to reopen if you need more help.

Thanks @igoventura for your help on multiple issues here! It's appreciated!

Thanks for replying @igoventura

libgdiplus is already installed on my computer. I have already shared my version numbers.

I have just tried compiling/installing libgdiplus from the source code. it did not worked. I still get the same error.

I think I have no right to re-open the issue. so it is up to you.

libc6-dev

did you install libc6-dev as well? It is required by libgdiplus

Also could you please try setting: LD_LIBRARY_PATH env variable to point to the location of libgdiplus.

Also you can use LD_DEBUG to find out which library it is actually not finding, because even though you have libgdiplus you could be missing a dependency like libc6-dev which would cause the load to fail.

Hello, I am using Fedora 30 and .net core 2.1 and I have exactly the same issue. I can see you suggest to install libc6-dev, but it's not available for Fedora. What I have installed is: glibc, glibc-devel, glibc-devel.i686, libgdiplus, libX11-devel, but it still doesn't work. Which packages should be installed to make it work on Fedora?

[oguzhantopcu]

I have installed all libraries you have suggested. I also downloaded libgdiplus source then compiled/installed myself. did not work.

I set env variable as you specified. Same error.

I have tried to use LD_DEBUG, I could not investigate anything since it is giving an output like a matrix (movie) window.

Alsı I have failed to redirect LD_DEBUG output to a file ">" or | tee is not working.

[oguzhantopcu]

Is it possible to re-open this issue since it is not resolved actually? @karelz

[safern]

@oguzhantopcu could you please run find -name libgdiplus* on your computer?

Try linking /usr/lib64/ to /usr/lib/.

Also, it would be great if you could share LD_DEBUG output. That would really help me understand where the runtime is trying to load libgdiplus from.

EDIT:
I didn't see that you tried to use LD_DEBUG when initially commented. Did you try setting a LD_DEBUG value for libraries only?

i.e: export LD_DEBUG=libs dotnet test ...

[oguzhantopcu]

find gives nothing but locate libgdiplus gives following

/usr/lib64/libgdiplus.so
/usr/lib64/libgdiplus.so.0

/usr/share/doc/libgdiplus/TODO
/usr/share/licenses/libgdiplus
/usr/share/licenses/libgdiplus/COPYING

what I have tried:

export LD_LIBRARY=/usr/lib/; dotnet test Pompa.Business.Tests.csproj --filter "FullyQualifiedName~Invoice_Cast"

export LD_LIBRARY=/usr/lib64/; dotnet test Pompa.Business.Tests.csproj --filter "FullyQualifiedName~Invoice_Cast"

export LD_LIBRARY=/usr/local/lib/; dotnet test Pompa.Business.Tests.csproj --filter "FullyQualifiedName~Invoice_Cast"

export LD_DEBUG=libs; dotnet test Pompa.Business.Tests.csproj --filter "FullyQualifiedName~Invoice_Cast"

The last one gives HUGE output, I can not examine it nor copy from the console. I can not redirect the output to the text file neither. ">" or | tee is not doing the trick.

[safern]

can you do the last one and grep for libgdiplus?

export LD_DEBUG=libs; dotnet test Pompa.Business.Tests.csproj --filter "FullyQualifiedName~Invoice_Cast" | grep libgdiplus
