@ -135,17 +135,25 @@ $ ./autogen.sh
$ ./configure
Please note that, by default, the configure script will assume we want to place
eudev under the /usr directory. If this is not accurate, we can supply an
alternative location using the "--prefix" flag. For instance, to place eudev
under the /usr/local directory tree, run the following:
Please note that building eudev requires a modern C compiler like gcc or clang.
Any other C compiler that conforms to the standards should work but that path
is not well tested and may require little tweaks to the code.
Please note that configure will install eudev under /usr by default. In case
that the desired installation directory is different that may be changed by
using the "--prefix" option as shown in the example below. To place eudev under
/usr/local, run the following:
$ ./configure --prefix /usr/local
Once eudev has been configured we can then perform the build.
Once eudev has been configured run make to build it:
$ make
Or alternatively, using more cores in parallel:
$ make -j 16
