Unable to perform static compilation of TimeZones.jl

[bmharsha]

I’m trying to create a system image of Julia with TimeZones.jl embedded, I encountered following error while building Julia (using release-0.5 branch).

I encountered similar error when I tried using Julia master

OS = Ubuntu 14.04
TimeZones version = 0.2.2

[omus]

Thanks for reporting this issue. I'll look into it today.

[aviks]

Does this package work correctly in standard precompile mode?

[omus]

TimeZones.jl does work with precompile. The UndefVarErroris coming from Mocking.jl. There seems to be something strange going on with static compilation and globals. Looking into it.

[omus]

Static compiliation may not respect the __init__ function (JuliaLang/julia#18115). I have a work around which I'll apply to Mocking.jl.

[omus]

__init__ works as intended with static compilation. I had a faulty impression with how I thought it worked. Fixing the issue in JuliaTesting/Mocking.jl#6

[omus]

@bmharsha can you verify that TimeZones.jl is can now be statically compiled? You'll need to use the latest version of Mocking.jl (v0.2.2) which should be published shortly:

Pkg.add("Mocking")
Pkg.checkout("Mocking", "master")

I just checked this fix on both Julia master and release-0.5, I was able to perform static compilation of TimeZones.jl, thank you very much for the quick fix @omus
