#!/bin/sh
# build.sh: build the benchmark driver of the original C WFDB library.
#
# Usage: benchmarks/c/build.sh OUTPUT_DIRECTORY
#
# Builds the unmodified WFDB Software Package 10.7.0 (third_party/
# wfdb-main.zip) with its own configure script and compiler options, as a
# user would install it (tests/reference/build_reference.sh with
# WFDBX_ORIGINAL=1; it needs libFLAC, or FLAC_PREFIX), into
# OUTPUT_DIRECTORY/wfdb, once; then compiles bench.c against that library as
# OUTPUT_DIRECTORY/wfdb_c_bench.  The tools of that build
# (OUTPUT_DIRECTORY/wfdb/bin) are the C tools that run.py times.
#
# This file is part of WFDB-x, an independent reimplementation of the WFDB
# Software Package in Python, C++, MATLAB/Octave, Rust, Julia, R and Kotlin.
# It has no counterpart in the original package.
