Unresolved External Symbol

[Komak57]

Getting a large collection of errors like Unresolved external symbol "declspec(dllimport) public: ..." when attempting to compile this project. All source appears to be bug-free, compiling Releast/x86, Bakkesmod SDK added as includes from both the GitHub installed version, and the BakkesMod installed version. I'm assuming this has something to do with the compiler settings, but I can't find a solution as to why.

Visual Studio 2017 v15.9.22 Visual Studio 2019 v16.5.4

This code was compiled as both the start of my own plugin, and as the original source from the original solution in the github. The errors following are from the plugin BMDiscord, which are identical to the source compile errors except for file names.

Solved. The current BakkesMod SDK runs on x64, not x86. Compiling accordingly resolves the external symbol errors.

Ah yes, sorry for my late response! I hope my project helps you out a little! :)
