Cannot build PhotonDemoParticle solution

Hi, I'm getting the following when trying to build. I'm using UE 4.26. Any help would be greatly appreciated.
cheers

Edit: After updating the PhotonLibrary Path to "-cpp_vc16_release_windows_md_" in PhotonDemoParticle.Build.cs it does build (still a few warnings ), hopefully this helps someone else with the same issue

1>[Upgrade]
1>[Upgrade] Using backward-compatible build settings. The latest version of UE4 sets the following values by default, which may require code changes:
1>[Upgrade] bLegacyPublicIncludePaths = false => Omits subfolders from public include paths to reduce compiler command line length. (Previously: true).
1>[Upgrade] ShadowVariableWarningLevel = WarningLevel.Error => Treats shadowed variable warnings as errors. (Previously: WarningLevel.Warning).
1>[Upgrade] PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs => Set in build.cs files to enables IWYU-style PCH model. See https://docs.unrealengine.com/en-US/Programming/BuildTools/UnrealBuildTool/IWYU/index.html. (Previously: PCHUsageMode.UseSharedPCHs).
1>[Upgrade] Suppress this message by setting 'DefaultBuildSettings = BuildSettingsVersion.V2;' in PhotonDemoParticleEditor.Target.cs, and explicitly overriding settings that differ from the new defaults.

  • Hi @deadstar619.
    LINK : fatal error LNK1181: cannot open input file 'C:\Users\marco\Downloads\Photon-Unreal-SDK_DemoParticle-UE4\Source\Photon\lib\Windows\Photon-cpp_vc14_release_windows_md_x64.lib'
    This error message says that Unreal can't find Photon-cpp_vc14_release_windows_md_x64.lib inside C:\Users\marco\Downloads\Photon-Unreal-SDK_DemoParticle-UE4\Source\Photon\lib\Windows.

    Copying the .libs files from the Windows SDK to the correct path inside the demo project like instructed at https://doc.photonengine.com/en-us/realtime/current/getting-started/unreal-engine will fix this error.

    However afterwards you will run into another build error:
    Unreal Engine 4.26 requires the vc15 variants of the Photon libraries and not the vc14 ones.
    Open 'C:\Users\marco\Downloads\Photon-Unreal-SDK_DemoParticle-UE4\Source\PhotonDemoParticle\PhotonDemoParticle.Build.cs' and change the 'vc14' in there to 'vc16' to link against the correct .lib files for the Unreal Engine version that you use.
