How to build and install the Mono libgdiplus.dll on a Mac with Homebrew (update: no longer needed, see comments)

mac-libgdiplus.sh

#!/bin/bash

# First install XQuartz, then...
brew install freetype fontconfig libpng
ln -s /opt/X11/include/X11 /usr/local/include/X11
git clone [email protected]:mono/libgdiplus
cd libgdiplus
./autogen.sh
make install

Just add
runtime.osx.10.10-x64.CoreCompat.System.Drawing
nuget package

I can confirm that Andotnet´s solution of installing the nuet package "runtime.osx.10.10-x64.CoreCompat.System.Drawing" solved the issue on MacOs Catalina 10.15.3 (19D76) when running a solution built on .NET Core 3.1.

I had before this installed "libgdiplus" using HomeBrew and also as part of the .NET Mono 6.6.0.166 installation. Doing a find in Terminal I could surmise that the library was installed to the path "/usr/local/lib/libgdiplus.dylib" but my application was unable to locate it.

Specifically the component that was unable to access libgdiplus was Telerik Reporting 14.0.20.219. Before updating this component it was able to find and access libgdiplus.

Thanks a lot Andotnet, you are a life saver!

It is work, thank you sir.

Awesome thanks @Andotnet adding runtime.osx.10.10-x64.CoreCompat.System.Drawing dependency solved the issue for MacOs Catalina 10.15.3!

Thanks for the help in getting this installed from this thread! Does anyone have any info on how to install libc6-dev on Mac at the moment, because I can't seem to work it out

Just add
runtime.osx.10.10-x64.CoreCompat.System.Drawing
nuget package

this was it, thx a lot!

This also worked for me. Was needed for the image components in ML.NET.

This NuGet was last published 1.5 years ago, which is concerning from a long-term perspective.
NuGet https://www.nuget.org/packages/runtime.osx.10.10-x64.CoreCompat.System.Drawing/ built from https://github.com/CoreCompat/libgdiplus-packaging.

I did not try the above mentioned brew install mono-libgdiplus, which may also work.

brew install mono-libgdiplus worked for me, the nuget approach didn't on Mojave.

I ran into this issue, when running a .NET 6.0 App, this is how I solved it

$ brew install mono-libgdiplus
$ sudo ln -s /opt/homebrew/opt/mono-libgdiplus/lib/libgdiplus.dylib /usr/local/share/dotnet/shared/Microsoft.NETCore.App/6.0.0

And that's it

To get this working with C#/System.Drawing, just do:

sudo ln -s /opt/homebrew/opt/mono-libgdiplus/lib/libgdiplus.dylib /usr/local/lib/

(Which is where the system looks for the library at runtime)

These two alone didn't fix the error on my M1 MacBook pro.
$ brew install mono-libgdiplus
$ sudo ln -s /opt/homebrew/opt/mono-libgdiplus/lib/libgdiplus.dylib /usr/local/share/dotnet/shared/Microsoft.NETCore.App/6.0.0

After this third command the program ran without error.
$ sudo ln -s /opt/homebrew/opt/mono-libgdiplus/lib/libgdiplus.dylib /usr/local/lib/

Solution for M1 Macbook pro

1. HOMEBREW_NO_AUTO_UPDATE=1 brew reinstall mono-libgdiplus
2. sudo ln -s /opt/homebrew/opt/mono-libgdiplus/lib/libgdiplus.dylib /usr/local/lib/liblibgdiplus

now works fine.

@hariharankanakaraja Thanks man! You saved my time. I have trapped here for 2 days since the compatibility of ARM Macs really suck.
