'Could not spawn setenv' error when creating an app with multiprocessing

[hotarolag]

I'm creating a very simple app that spawns two processes and prints a who_am_i function. When I use this module with Julia I don't have any problem with it, but when I create the app I have a IOError: could not spawn setenv error. It seems it can't find any julia executable and crashes.

The code is the following:

module parallel_test
	using Distributed

	module parallel_test2
		using Distributed
		function main()
			addprocs(2;exeflags="--project")
			@eval @everywhere using parallel_test
			println(nprocs())
			pmap(t->who_am_i(t),[t for t = 1:50])
		end
		function who_am_i(t)
			n = myid()
			println("$t - I'm process number $n")
		end
	end


	using .parallel_test2
	function julia_main()
		try
			parallel_test2.main()
		catch
			Base.invokelatest(Base.display_error, Base.catch_stack())
			return 1
		end
		return 0
	end


end # module
