Here is what worked for me with Unity3D 5.3: - If in your Unity Build Setting->Player Setting->Other Settings, "API Compatibility Level" is ".Net 2.0", create a file under your Unity Asset folder called gmcs.rsp, add this following line to the file: -unsafe Close Unity and open it again. - If the "API Compatibility Level" is ".Net 2.0 Subset", the above file name should be: smcs.rsp.

Open the file called compile_any.pl and in the section "# Run the csharp compiler" change @Base_Args options as below:

my @base_args=($mono_path, $mcs_path, '-debug', '-unsafe', '-target:library', '-nowarn:0169', '-out:'.$output, );

  • Do you have more than one project? May be that you need to check that setting on more than one project.
  • the unsafe code is in the c# script that attached to an object in unity, what then?
  • Is the unity project a C# project? If so, there is also a property page for this. If not, I simply not know, how unity is executing the script.
  • ok, i know i need to add the option\flag but i dont know how to get there
  • In MonoDevelop: menu Project/Assembly-CSharp Options then Build/General/ Allow unsafe
  • This was the only usefull answer for me. Since I can not use .NET 2.0 Subset and my Unity Project Settings do not have the option to allow unsafe code.
  • when targeting the .NET 3.5 Equivalent (deprecated) scripting runtime version, mcs is used with mcs.rsp, and when targeting the .NET 4.x Eqivalent scripting runtime version compiler, csc is used with csc.rsp.
  • i am running from a pc
  • Miloš Selečéni, which version of Unity is this for? Mine has a Frameworks folder, but no MonoCompiler.framework.
