This script takes a small subset of autoconf arguments (such as --prefix) and uses them to tailor the installation destinations and generated pkg-config manifest so that distributions should be able to just use this script. Arguments: The following autoconf arguments are accepted by this script. The value in brackets is the default value used if the flags are not specified. --prefix=[$DEFAULT_PREFIX] --exec-prefix=[PREFIX] --includedir=[EPREFIX/include] --libdir=[EPREFIX/lib(64)] (lib64 is used if available) --pkgconfigdir=[LIBDIR/pkgconfig] As with automake, if the DESTDIR= environment variable is set, this script will install the files into DESTDIR as though it were the root of the filesystem. This is usually used for distribution packaging. You can also pass environment variables as command-line arguments. Example: In an openSUSE rpm spec, this script could be used like this: %install ./install.sh \\ DESTDIR=%{buildroot} \\ --prefix=%{_prefix} \\ --exec-prefix=%{_exec_prefix} \\ --includedir=%{_includedir} \\ --libdir=%{_libdir} This script is part of the libpathrs project.
