Compile errors using WebGl plattform
Hi,
I want to add WebGl plattform support for my project and just struggle with the following errors compiling in WebGl on Unity 5.0.0f4. Maybe you have some ideas fixing those. Especially what dll's work with WebGl and which won't. Thank's in advance!
Best, Andre

Running a new project with empty scene does compile. Thus it seems to be a problem with the used api/dll's
at tanoshimi: Thank you for your answer. The reason why i use 5.0.0 is that i'm not doing it for myself, but for the customers who almost never have the newest unity version. Thus I try to develope for the oldest unity version possible. WebGL was first introduced with Unity 5.0.0 and I would like to develope for the lowest version possible. But you're right - I should try if it compiles using newer Unity versions.
Thanks a lot!
Now, it seems that compiling with Unity 5.3.1 not works neither. But the error log is shorter and a bit different:

etc..
so, it's probably the System.Drawing library..
Best Answer
Okay, I found the answer:
You need to set Api Compatibility Level to .Net 2.0. And you need to use Unity 5.2.0f3 upwards. This fixes all errors.
Thanks alot!
Best, Andre
5.0.0 is old! WebGL export is still very much a bleeding-edge feature, so if you want to use it you should always be running the latest version.
