HI, i’ m trying to build the engine from the source several time but always end up[ on compilation error. I did follow the readme, launched the setup.bat and the generatescript aswell. I did try to clean the repo and try again but always endup with those errors:

Do I miss something?

Some error for me. Wait developers fixing this bug

@Kanthuns, @Andrea_92

I fixed this error by moving the Git repo from the default location under the user home folder to a new root folder with a much shorter name and the error disappeared.

In my case, it was because the file path was too long for these files, specifically “…\Plugins\Experimental\NeuralNetworkInference\Source\ThirdParty\ONNXRuntime_2021_11_30\Private_DML\Windows\core\providers\dml\DmlExecutionProvider\src\Operators\DmlOperatorMeanVarianceNormalization.cpp”

Much more better, moving the directory to the root reduced the nummber of errors to 3.

I succeed by using the test branch (ue5-release-engine-test) and the staging one.
I’m not trying anymore the other ue5 branches.
