# psycopg_c build fix
142
142
#
143
-
# psycopg_c's setup.py runs `pg_config` as a bare command via
144
-
# subprocess. pip's build-isolation spawns a child process that
145
-
# inherits PATH, but in a Nixery container:
146
-
# 1. pg_config lives deep in /nix/store/…/bin/
147
-
# 2. The Nix profile PATH entry might not survive pip's venv
148
-
# activation or build-env overlay
149
-
# 3. /usr/bin and /usr/local/bin may not even exist
143
+
# pip's PEP 517 build-isolation spawns an isolated subprocess with
144
+
# its own PATH overlay (/tmp/pip-build-env-*/overlay/…) that
145
+
# shadows /usr/bin, /usr/local/bin, and any PATH we export here.
146
+
# The metadata-generation phase calls `pg_config` as a bare command
147
+
# via subprocess.run(["pg_config", ...]) using the ambient PATH —
148
+
# NOT the PG_CONFIG env var — so symlinks and exports alone fail.
150
149
#
151
-
# Strategy: find pg_config, then make it reachable by EVERY
152
-
# conceivable PATH lookup — symlinks, PATH prepend, pip config,
153
-
# and global env.
150
+
# Fix: use --no-build-isolation for psycopg[c] so the build runs
151
+
# directly in our environment where pg_config is on PATH and
152
+
# PG_CONFIG is exported. We pre-install the build deps (setuptools,
153
+
# wheel) so the non-isolated build succeeds.
