Hi,

I'm currently experimenting with modifications of the asdf-build-system
to see if it can be simplified.

I tried adding a profile hook that creates the ASDF configuration files
in 'etc/common-lisp/' based on the lisp packages that are present in the
manifest. When using 'guix environment -C --ad-hoc sbcl-lift' for
example, the configuration files are created and contain the right paths
for the sources and compiled files of sbcl-lift, which allows sbcl to
find and load the library.

However, when building a package depending on sbcl-lift, for example
with 'guix build sbcl-trivial-backtrace', sbcl fails to find sbcl-lift.
So it seems that the build environment created by 'guix build' doesn't
run profile hooks, and the ASDF configuration files are missing.

Is there a way to generate files and add them to the environment created
by 'guix build' as it can be done with profile hooks?

Hi Guillaume,

Thanks for taking a shot at this ;)

Why would we need to generate the ASDF configuration file in a hook?
Can't we do it at build time?

Cheers!

Yes, the build system can do whatever it wants.  The
texlive-build-system, for example, builds a union directory from all TeX
Live inputs and then modifies the configuration file.

Thanks for the pointer, it has been very useful.

I got rid of the hook and now I'm creating all the required files/links
at build time in 'etc/common-lisp/source-registry.conf.d/' and in
'etc/common-lisp/asdf-output-translations.conf.d/'.
It seems to work well with packages having simple definitions. Now
I have to check and adapt the more complex ones.

Great!
Don't hesitate the share your work on a wip- branch if it gets too overwhelming.

In the past I discussed the idea of defining the Common Lisp packages
this way: move the sbcl- and ecl- packages to the "sbcl" and "ecl"
outputs respectively.
The "sbcl" output can be used to confirm the package builds properly.

Another thing we need to fix is support for the package-infered systems
like cl-dbus.

Cheers!
