Simple install procedure======================== % gzip -cd libusb-@LIBUSB_VERSION@.tar.gz | tar xvf - # unpack the sources % cd libusb-@LIBUSB_VERSION@ # change to the toplevel directory % ./configure # run the `configure' script % make # build libusb [ Become root if necessary ] % make install # install libusbThe Nitty-Gritty================The 'configure' script can be given a number of options to enableand disable various features. For a complete list, type: ./configure --helpA few of the more important ones:* --prefix=PREFIX install architecture-independent files in PREFIX [ Defaults to /usr/local ]* --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX [ Defaults to the value given to --prefix ]Options can be given to the compiler and linker by settingenvironment variables before running configure. A few of the moreimportant ones: CC : The C compiler to use CPPFLAGS : Flags for the C preprocesser such as -I and -D CFLAGS : C compiler flagsThe most important use of this is to set theoptimization/debugging flags. For instance, to compile with nodebugging information at all, run configure as: CFLAGS=-O2 ./configure # Bourne compatible shells (sh/bash/zsh)or, setenv CFLAGS -O2 ; ./configure # csh and variantsInstallation directories========================The location of the installed files is determined by the --prefixand --exec-prefix options given to configure. There are also moredetailed flags to control individual directories. However, theuse of these flags is not tested.A shell script libusb-config is created during the configureprocess, and installed in the bin/ directory($exec_prefix/bin). This is used to determine the location of libusbwhen building applications. If you move libusb after installation,it will be necessary to edit this file.
