Enzyme Julia 1.11 UndefVarError: `CodeCache` not defined in `GPUCompiler`

[jakubMitura14]

Hello I have some very slow compiling kernels , and wanted to use Ahead of Time Compilation [1] to save them. However before i started experimenting with that I have an issue that Enzyme will not work with Julia 1.11 . I was trying to add enzyme from github and registry and result the same.

Pkg.add(url="https://github.com/EnzymeAD/Enzyme.jl.git")

Main issue seems to be

UndefVarError: `CodeCache` not defined in `GPUCompiler`

full error.

So what was the solution? I'm getting the same issue with Julia 1.11.1 and I don't see a single detail on how to resolve this

[wsmoses]

For future readers, per https://discourse.julialang.org/t/scimlsensitivity-jl-precompile-error-because-of-enzyme/122561 this has been fixed in Enzyme and you need to update to a later version.
