libusb_vhci

Этот проект состоит из драйвера ядра Linux и некоторых пользовательских библиотек. Они позволяют процессу создать виртуальный хост-контроллер USB. Реальные или виртуальные USB-устройства могут быть «подключены» к этому контроллеру.

Basic Installation

These are generic installation instructions.

The configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a Makefile' in each directory of the package. It may also create one or more .h' files containing system-dependent definitions. Finally, it creates a shell script config.status' that you can run in the future to recreate the current configuration, a file config.cache' that saves the results of its tests to speed up reconfiguring, and a file config.log' containing compiler output (useful mainly for debugging `configure').

If you need to do unusual things to compile the package, please try to figure out how configure' could check whether to do them, and mail diffs or instructions to the address given in the README' so they can be considered for the next release. If at some point `config.cache' contains results you don't want to keep, you may remove or edit it.

The file configure.in' is used to create configure' by a program called autoconf'. You only need configure.in' if you want to change it or regenerate configure' using a newer version of autoconf'.

The simplest way to compile this package is:

1. cd' to the directory containing the package's source code and type ./configure' to configure the package for your system. If you're using csh' on an old version of System V, you might need to type sh ./configure' instead to prevent csh' from trying to execute configure' itself.

   Running `configure' takes a while. While running, it prints some messages telling which features it is checking for.

2. Type `make' to compile the package.

3. Type `make install' to install the programs and any data files and documentation.

4. You can remove the program binaries and object files from the source code directory by typing `make clean'.

Compilers and Options

Some systems require unusual options for compilation or linking that the configure' script does not know about. You can give configure' initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure

Or on systems that have the `env' program, you can do it like this: env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure

Compiling For Multiple Architectures

You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of make' that supports the VPATH' variable, such as GNU make'. cd' to the directory where you want the object files and executables to go and run the configure' script. configure' automatically checks for the source code in the directory that configure' is in and in ..'.

If you have to use a make' that does not supports the VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture.

Installation Names

By default, make install' will install the package's files in /usr/local/bin', /usr/local/man', etc. You can specify an installation prefix other than /usr/local' by giving configure' the option --prefix=PATH'.

You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give configure' the option --exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix.

If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving configure' the option --program-prefix=PREFIX' or `--program-suffix=SUFFIX'.

Optional Features

Some packages pay attention to --enable-FEATURE' options to configure', where FEATURE indicates an optional part of the package. They may also pay attention to --with-PACKAGE' options, where PACKAGE is something like gnu-as' or x' (for the X Window System). The README' should mention any --enable-' and --with-' options that the package recognizes.

For packages that use the X Window System, configure' can usually find the X include and library files automatically, but if it doesn't, you can use the configure' options --x-includes=DIR' and --x-libraries=DIR' to specify their locations.

Specifying the System Type

There may be some features configure' can not figure out automatically, but needs to determine by the type of host the package will run on. Usually configure' can figure that out, but if it prints a message saying it can not guess the host type, give it the --host=TYPE' option. TYPE can either be a short name for the system type, such as sun4', or a canonical name with three fields: CPU-COMPANY-SYSTEM

See the file config.sub' for the possible values of each field. If config.sub' isn't included in this package, then this package doesn't need to know the host type.

If you are building compiler tools for cross-compiling, you can also use the --target=TYPE' option to select the type of system they will produce code for and the --build=TYPE' option to select the type of system on which you are compiling the package.

Sharing Defaults

If you want to set default values for configure' scripts to share, you can create a site shell script called config.site' that gives default values for variables like CC', cache_file', and prefix'. configure' looks for PREFIX/share/config.site' if it exists, then PREFIX/etc/config.site' if it exists. Or, you can set the CONFIG_SITE' environment variable to the location of the site script. A warning: not all configure' scripts look for a site script.

Operation Controls

`configure' recognizes the following options to control how it operates.

--cache-file=FILE' Use and save the results of the tests in FILE instead of ./config.cache'. Set FILE to /dev/null' to disable caching, for debugging configure'.

--help' Print a summary of the options to configure', and exit.

--quiet' --silent' `-q' Do not print messages saying which checks are being made.

--srcdir=DIR' Look for the package's source code in directory DIR. Usually configure' can determine that directory automatically.

--version' Print the version of Autoconf used to generate the configure' script, and exit.

`configure' also accepts some other, not widely useful, options.
