# This file constructs the standard build environment for the
|
||
# Linux platform. It's completely pure; that is, it relies on no
|
||
# external (non-Nix) tools, such as /usr/bin/gcc, and it contains a C
|
||
# compiler and linker that do not search in default locations,
|
||
# ensuring purity of components produced by it.
|
||
#
|
||
# It starts from prebuilt seed bootstrapFiles and creates a series of
|
||
# nixpkgs instances (stages) to gradually rebuild stdenv, which
|
||
# is used to build all other packages (including the bootstrapFiles).
|
||
#
|
||
# Goals of the bootstrap process:
|
||
# 1. final stdenv must not reference any of the bootstrap files.
|
||
# 2. final stdenv must not contain any of the bootstrap files.
|
||
# 3. final stdenv must not contain any of the files directly
|
||
# generated by the bootstrap code generators (assembler, linker,
|
||
# compiler).
|
||
#
|
||
# These goals ensure that final packages and final stdenv are built
|
||
# exclusively using nixpkgs package definitions and don't depend
|
||
# on bootstrapTools (via direct references, inclusion
|
||
# of copied code, or code compiled directly by bootstrapTools).
|
||
#
|
||
# Stages are described below along with their definitions.
|
||
#
|
||
# Debugging stdenv dependency graph:
|
||
# An useful tool to explore dependencies across stages is to use
|
||
# '__bootPackages' attribute of 'stdenv. Examples of last 3 stages:
|
||
# - stdenv
|
||
# - stdenv.__bootPackages.stdenv
|
||
# - stdenv.__bootPackages.stdenv.__bootPackages.stdenv
|
||
# - ... and so on.
|
||
#
|
||
# To explore build-time dependencies in graphical form one can use
|
||
# the following:
|
||
# $ nix-store --query --graph $(nix-instantiate -A stdenv) |
|
||
# grep -P -v '[.]sh|[.]patch|bash|[.]tar' | # avoid clutter
|
||
# dot -Tsvg > stdenv-final.svg
|
||
#
|
||
# To find all the packages built by a particular stdenv instance:
|
||
# $ for stage in 0 1 2 3 4; do
|
||
# echo "stage${stage} used in:"
|
||
# nix-store --query --graph $(nix-instantiate -A stdenv) |
|
||
# grep -P ".*bootstrap-stage${stage}-stdenv.*->.*" |
|
||
# sed 's/"[0-9a-z]\{32\}-/"/g'
|
||
# done
|
||
#
|
||
# To verify which stdenv was used to build a given final package:
|
||
# $ nix-store --query --graph $(nix-instantiate -A stdenv) |
|
||
# grep -P -v '[.]sh|[.]patch|bash|[.]tar' |
|
||
# grep -P '.*stdenv.*->.*glibc-2'
|
||
# "...-bootstrap-stage2-stdenv-linux.drv" -> "...-glibc-2.35-224.drv";
|
||
#
|
||
# For a TUI (rather than CLI) view, you can use:
|
||
#
|
||
# $ nix-tree --derivation $(nix-instantiate -A stdenv)
