Thanks @Jameson,
I am a bit confused about "you are not adding any code to the system image
(`--eval nothing`)". According to your blog
http://juliacomputing.com/blog/2016/02/09/static-julia.html , I think that
this is a crucial point to obtain a small sized dll. Am I right?
What is then the right way to emit "ccallable" declarations in order to
export julia function(s)? (foo in our example from the original post in
this thread)
Is it okay to work with current version of julia 0.4.5. or I have to switch
to another version; If yes, to which one?
Thanks in advance.
