Installer should surface external Cargo target usage when local disk is tight #54
Description
Activity
Implemented the installer fix locally and validated it two ways:
./scripts/install/test-source-build-install.sh- real source install with build outputs on
/Volumes/Dzianis-3:
CODEX_INSTALL_DIR=$HOME/.cargo/bin CARGO_TARGET_DIR=/Volumes/Dzianis-3/codex-target TMPDIR=/Volumes/Dzianis-3/codex-tmp CODEX_BUILD_JOBS=1 ./install.sh
The real install completed successfully and produced:
/Volumes/Dzianis-3/codex-target/release/codex/Users/engineer/.cargo/bin/codex
Next step is opening the PR linked to this issue.
PR opened: #55
It includes the installer fix, docs update, and shell-test coverage for external
CARGO_TARGET_DIRusage.
Summary
./install.shcan fail on macOS/Linux withNo space left on devicewhen the defaultcodex-rs/targetlives on a smaller root volume, even though the user may have a large secondary volume available.The script already honors
CARGO_TARGET_DIR, but the current help/error path does not make that recovery obvious enough.Desired outcome
CARGO_TARGET_DIRfor source builds.Example
