GPUCompiler problems.

[lpawela]

After compiling an app which uses CUDA.jl and moving to another machine I get

./test_comp/bin/TestCUDA 
fatal: error thrown and no exception handler available.
InitError(mod=:GPUCompiler, error=ErrorException("type Nothing has no field major"))

Launch a clean instance of julia with JULIA_DEPOT_PATH=tmp julia, then install PackageCompiler and build app

]add PackageCompiler
julia> create_app(".", "test_comp", force=true)

I think there is a string relocation issue from: https://github.com/JuliaGPU/GPUCompiler.jl/commit/c0c9ab7d2604c44dfb90a99332ba3eadad3679d7

So Base.pkgversion isn't available (returns nothing) in compiled apps?

[sjkelly]

I think that is the case because the module comes from the sysimg instead. For example in the 1.10 REPL:

julia> using LinearAlgebra

julia> typeof(Base.pkgversion(LinearAlgebra))
Nothing

A proposed fix has been filed here: https://github.com/JuliaGPU/GPUCompiler.jl/pull/589

I am closing this since this is not likely a direct PackageCompiler issue.
