Re: [Chicken-users] Windows deployment - Numbers egg

[Robert Herman]

Peter,

Thank you, that explains everything I was confused about!

The only issue remaining is the error with the compile deploy process trying to copy files from the CHICKEN directory. I didn't rename the CHICKEN directory to CHICKEN-IUP, that's what the pre-built binary for Windows with IUP called it, and the path is correct, but libchicken.dll is in c:\chicken-iup\bin not c:\chicken-iup\lib. Instead, c:\chicken-iup\lib has libchicken.a and libchicken.dll.a within it. I only needed to manually copy numbers.so from the C:\chicken-iup\lib\chicken\7 directory to make it work.

This looks like you may have renamed the chicken directory.  Is that
possible?

I'm not sure if that's going to work in the general case.  If you
include an egg that itself depends on other eggs, it might not be
able to load them because the egg doesn't know it's linked into a
deployed executable.

It's supposed to generate a statically linked executable.

I think those options are supposed to be mutually exclusive, but
maybe the latter overrides the former.

Compiling a program statically only works if you also have static
versions of all the libraries it uses.  Most eggs don't install
static copies of their libraries (neither does numbers).  Besides,
(use numbers) says "load the numbers module dynamically".  If you
want to compile statically, you'd have to do something like

(declare (uses numbers))
(import numbers)

But I'm not 100% sure.  This is going to be made easier in CHICKEN 5,
at least that's the plan.

It does include libchicken.dll (but not numbers because you didn't
declare it statically)

You can't load a .dll file statically; it's inherently dynamic.
However, if you have libchicken.a, you can link _that_ statically
into your program.  Like I said, you'll also need to somehow create
a "numbers.a" file to link into your program.

Does the file it mentions exist?

Cheers,
