Refactoring: project structure

[shegeley]

Accomplishments:

1. Changed project structure:

• Moved all .c code to libguile-wayland and all .scm to /modules as in other .scm + .c projects (see guile-ssh, guile-xosd ...)
• Partitioned makefiles accordingly

2. Changed guix.scm and a way that load extension (coped from guile-ssh). Now it can be build successfully with guix build -f guix.scm
3. example/... are now ....scm.in and included in configure.ac

Problems: after build with guix build -f guix.scm I couldn't load (bytestructure-class) extension.

and change some:

• guix.scm phase no end with #t
• Makefile.am build libguile-wayland before modules/wayland
• pre-inst-env.in not $(abs_top_builddir), just $abs_top_builddir
• examples add --no-auto-compile -e main at head
• configure.ac chmod +x for exampels.

Problems: after build with guix build -f guix.scm I couldn't load (bytestructure-class) extension.

because it is propagated-inputs, so just use guix shell guile -f guix.scm -- guile , guix will add guile-bytestructure-class to profile,and then you can use ,use (wayland).

[Z572]

(bytestructures guile) beacuse guix propagated guile-git , guile-git propagated guile-bytestructures

[shegeley]

Excuse me. I didn't «get and change some...». Would you like me to change all the listed back?

Makefile.am build libguile-wayland before modules/wayland

Yes. It is how it works in some other modules I saw (guile-ssh, guile-xosd). First the build libguile-x.la and then uses it in modules

[shegeley]

Are you sure that (bytestructure-class) is packed properly?
On the latest master (with propagated-inputs) I get

no, I added these changes at commit time.

[Z572]

emm, it works for me, maybe need guix shell guile -f guix.scm --rebuild-cache -- guile？

[shegeley]

guix shell guile -f guix.scm --rebuild-cache -- guile

Absolutely. Thanks a lot. The problem was in cache.
