Alpine Linux 的 /sbin/ldconfig 和其他发行版不同，摘录如下：
https://git.alpinelinux.org/aports/blame/main/musl/ldconfig?h=3.10-stable
ldconfig is used by some packages' install script to create the SONAME symlinks in the DESTDIR. do those symlinks for non-system directories.
#!/bin/sh
scan_dirs() {
scanelf -qS "$@" | while read SONAME FILE; do
TARGET="${FILE##*/}"
LINK="${FILE%/*}/$SONAME"
case "$FILE" in
/lib/*|/usr/lib/*|/usr/local/lib/*) ;;
*) [ -h "$LINK" -o ! -e "$LINK" ] && ln -sf "$TARGET" "$LINK"
esac
done
return 0
}
# eat ldconfig options
while getopts "nNvXvf:C:r:" opt; do
:
done
shift $(( $OPTIND - 1 ))
[ $# -gt 0 ] && scan_dirs "$@"
这可能会带来一些失败，对不是强依赖的，可以手动指定 LIBPATH=/usr/lib INCPATH=/usr/include.
