Failed to build Valheim - System.DllNotFoundException

[ProfAronnax]

Hi there, unfortunately i was not able to build the valheim client. Followoing the instructions i was not able utilizing brew to install the dotnet@7 version, but instead i was recomended to installe the current version 8 which seems to work.. Now i am stuck with executing the build.sh script.

Plattform M1 Max with 14.2.1 (23C71)

I hope you can give me some help to get it working, best regards Leif

I got the same error message when installing dotnet with brew (because it installed the latest version 8 but not 7). Check your dotnet version, and install dotnet 7 if necessary. Please, see the following issue https://github.com/timkurvers/valheim-macos/issues/74#issuecomment-1868533052

@ProfAronnax Could you give the instructions in #76 a shot? It drops the dotnet requirement, which hopefully bypasses the issue you're running into altogether.

Hi @timkurvers, i will close this issue -> workaround described under: https://github.com/timkurvers/valheim-macos/pull/76#issue-2057853945
