+### Installation Paths
|
|
+
|
|
+ * `prefix`: The directory prefix for (almost) all files to be installed.
|
|
+ Distributions may want to set this to `/usr`.
|
|
+ **Note**: for multipath-tools, unlike many other packages, `prefix`
|
|
+ defaults to the empty string, which resolves to the root directory (`/`).
|
|
+ * `usr_prefix`: where to install those parts of the code that aren't necessary
|
|
+ for booting. You may want to set this to `/usr` if `prefix` is empty.
|
|
+ * `systemd_prefix`: Prefix for systemd-related files. It defaults to `/usr`.
|
|
+ Some systemd installations use separate `prefix` and `rootprefix`. On such
|
|
+ a distribution, set `prefix`, and override `unitdir` to use systemd's
|
|
+ `rootprefix`.
|
|
+ * `LIB`: the subdirectory under `prefix` where shared libraries will be
|
|
+ installed. By default, the makefile uses `/lib64` if this directory is
|
|
+ found on the build system, and `/lib` otherwise.
|
|
+
|
|
+See also `configdir` and `plugindir` above. See `Makefile.inc` for more
|
|
+fine-grained control.
|
|
+
|
|
+### Compiler Options
|
|
+
|
|
+Use `OPTFLAGS` to change optimization-related compiler options;
|
|
+e.g. `OPTFLAGS="-g -O0"` to disable all optimizations.
