Problem with FFTW=1.4.3 ignoring DEPOT_PATH variable at runtime

[theweaklink]

hi there,

we have noticed a problem on our end with FFTW 1.4.3 which seems to ignore the env variable JULIA_DEPOT_PATH (internally in Julia DEPOT_PATH) when loading the library.

We have been building an image with PkgCompiler: in our build environment (clean Docker image), the depot path is /build_jl/depot.
With FFTW 1.4.2 and 1.4.1 we havent had any issue loading the library as we are setting the env var JULIA_DEPOT_PATH (e.g. /my/new/depot) before loading the library and it has been working fine so far.
However, since 1.4.3, setting the env var JULIA_DEPOT_PATH doesn't do anything and we get the error:

InitError(mod=:FFTW, error=ErrorException("could not load library "/build_jl/depot/artifacts/81791030d1dcd08bf0c67b3e8224cb573d0f5a0a/lib/libfftw3.so"

clearly pointing to the JULIA_DEPOT_PATH set at build time and not at runtime.

It seems that the PR #207 was the only change between 1.4.2 and 1.4.3 but I can't pinpoint more than that (sorry!).
Is that actually possible to make the #207 compatible with specifying the JULIA_DEPOT_PATH at runtime?

I think this should be fixed in the new release.

Sounds good, thanks for the follow up, I'll check once the release comes out and let you know.

The release should already be out.

Indeed, my bad for the release.
I just checked with FFTW 1.4.5 and it works like a charm, there is no longer an issue. Thanks very much for the fix!
cheers
