Hello David!

I think there is some confusion, or at least something I am unaware of:

I am running a guix command like this:

~~~~Makefile~~~~
.POSIX:
.RECIPEPREFIX = >
.DELETE_ON_ERROR:

MAKEFLAGS += --warn-undefined-variables
MAKEFLAGS += --no-builtin-rules

# --no-grafts is required to run g-golf examples. Some bug in Guix.
SHELL ::= guix time-machine --channels=guix-env/channels.scm -- shell --no-grafts --check --manifest=guix-env/manifest.scm -- bash -c
.SHELLFLAGS = -Euo pipefail -c

GUILE_LOAD_PATH ::= .
# GUILE_LOAD_PATH += utils

GUILE_LOAD_PATH_ARG ::= $(foreach dir, $(GUILE_LOAD_PATH),-L $(dir))

.PHONY: run
run:
> guile $(GUILE_LOAD_PATH_ARG) main.scm

.PHONY: repl
repl:
> guile
~~~~

In this Makefile I am defining what shell make uses. I use guix time-machine to 
make sure the result is reproducible, locked to one specific commit, described 
using the channels.scm. Then there is the guix shell command with the 
--no-grafts argument. In that guix shell I am then running a normal shell to run 
the guile command in, with all the required directories of my project added to 
the load path. There is no profile, which would have a well known location of 
the bin directory, only that temporary shell, that has a bin directory somewhere 
at location with unpredictable name. If I update to a newer commit for 
time-machine, then that location will also change. At no point I am (currently!) 
creating a profile with predictable/specifiable bin dir location to go to. There 
is no predictable prefix, as far as I am aware.

It may be, that G-Golf is not meant or ready to be used in such a way.

To summarize it:

I guess, I want to have a single command, that will make the code run based on 
reproducible dependencies (specified somewhere, in my case in manifest.scm and 
channels.scm), so that I can run it on another machine, where there is guix 
installed. A few descriptive/declarative files like channels.scm and 
manifest.scm are OK, since I can simply commit them in my repo and all will be 
reproducible again. Usually I can run Guile code like this, with reproducible 
result on other machines.

I have some ideas:

(1) switch to making a guix profile instead, so that the bin directory is in a 
predictable location and then try running the ./hello-world thing (but how to do 
it with my own code??)

(2) perhaps there is a way to ask guix shell where its bin directory is, so that 
I can switch to that automatically to then run the code from there?

(3) Generally I would like to run the code, not a prebuilt example package. How 
else do I know, that the code listed in the repository of G-Golf as example 
actually works?

Best regards,
Zelphir
