Build hangs

[solcat124]

I've successfully used ApplicationBuilder on MacOS and Linux Mint using a couple of different source files. (Success meaning the build process completes and I'm able to run the resulting app.) I'm now trying to use the build function on an AWS instance of Linux (Ubuntu 18), but it hangs. (I've let this run for an hour or two). The results below are for the example file commandline_hello.jl.

Any suggestions on how to get this to work?

I modified a local copy of ApplicationBuilder to get more output. It appears that the problem occurs within PackageCompiler, where it hangs on
append!(Base.atexit_hooks, atexit_hook_copy)

I don't understand why it hangs here, so I'm still unsure what to try next.

Here is the output:

I'm sorry i didn't respond for so long.

I'm not sure why it's hanging.. This isn't a great answer, but PackageCompiler is basically unmaintained at this point, but there is a revival going on in https://github.com/KristofferC/PackageCompilerX.jl. If you still have need of package compilation, you might try looking there?

Thanks! :)
