Hi,
I’m trying to build a C++ project in UE4. When I try building the game I get a build error LNK1181. I’m working through the solution to that (from here) which requires right-clicking the .uproject file and selecting “Generate Visual Studio Files”. When I do this, I get error CR0101, as below.
I understand that this is basically saying there is already a reference to FModStudio - but I’m unsure how to resolve it.
I’m using 4.7, after failed attempts to use 4.8 to launch the project. Due to incompatibility issues between UE4 and FMod, I require a solution for 4.7
