Using .NET with MONO under OSX 10.10

Posted 10 years ago


I'm quite new using Mathematica Home Edition and .NET on my Mac Book running OSX10.10. In order to use .NET I installed the latest MONO version "MonoFramework-MDK-3.12.1-macosx10.xamarin.x86.pkg". MONO install path is "/Library/Frameworks/Mono.framework/Versions/3.12.1/lib/libmonoboehm-2.0.1.dylib"

But when I try to establish a .NET communication e.g. with Needs["NETLink`"] InstallNET[]; the only message is : Cannot set current directory to \ /Applications/\ framework/. >>

The path is wrong as the Mathematica installation path is : /Applications/ So the path "../contents/contents/.." seems to be the issue.

Anybody out there to provide some advice ? Thank a lot in advance.

FYI, newer versions of Mono no longer install to "/usr/bin" so the default option value of InstallNET,

OptionValue[InstallNET, "MonoPath"]  (* returns "mono" *)

may no longer be found. Instead, set this path yourself when using InstallNET:

InstallNET["MonoPath" -> "/Library/Frameworks/Mono.framework/Versions/Current/Commands/mono"]

Hi Stefan,

This is an issue in Mathematica 10.0.2. It is fixed in Mathematica 10.1.0, but if you don't have access to that version, here's a workaround:

Locate this file:

FileNameJoin[{$InstallationDirectory, "SystemFiles", "Links", "NETLink", "Kernel", "InstallNET.m"}]

and then replace it with the file attached.
