# Build the upstream SMLib/SM_API C++ reference kernel (and its test apps)
|
|
# into $OUT: $SOLIDCORE_CPP_DIR if set (the same override solidcore-ffi honours),
|
|
# else <repo>/bin/cpp. See plan/baseline.md.

|
|
# Usage: harness/cpp/build.sh [--no-tests] [--jobs N] [--clean]

#
|
|
# Run it from the main tree; git worktrees reuse that build by exporting
|
|
# SOLIDCORE_CPP_DIR=<main tree>/bin/cpp. Running it from a worktree with that override
|
|
# is also safe: the CMake build tree is keyed by this harness's source path, so each
|
|
# source tree gets its own build dir and CMake never sees a mismatched source.
|
|
#
|
|
# Outputs (in $OUT):
|
|
# build-<hash>/ CMake/ninja build tree; <hash> = first 8 hex of the
|
|
# sha256 of this harness's absolute path. A legacy
|
|
# build/ whose CMake source is this harness is reused.
