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

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.
