为ubuntu 安装libusb

-------------------------------------------------------------------------------------------

#更新历史：

#1. 使用libusb 源码安装libusb.

#2. 使用apt-get install libusb* 安装libusb。

--------------------------------------------------------------------------------------------

今天突然发现原来之前写的博文是用源码安装libusb的方法。

一般，软件包比较大的话可以下载源代码进行安装，这样比较方便。

在这个问题上，其实可以直接使用apt-get install libusb* 来安装usb相关的库文件。

最初以为apt-get install 只能安装软件，后来自己的ubuntu提示更新软件，看了以下可以更新的列表发现也有lib库。

在ubuntu软件中心搜索libusb 也能搜到相关的库，而且apt-get install 支持 * 通配符。之前直接apt-get install libusb 失败了就误以为没法更新库文件了。

现在发现linux 命令行工具以及通配符太好用了。 ls *usb* 也可以。

最近遇到新装的ubuntu 没有libusb,而编译android 源码的时候需要gcc选项中有lusb，也就是需要链接libusb.a。

在网上只找到了libusb的源码。

http://www.libusb.org/

下载源码​libusb-1.0.9.tar.bz2(2012-04-20)，在源码中INSTALL 文件，有详细的介绍如何把这些源码编译并安装到ubuntu系统中。

建议使用老版本，libusb-0.1.12.tar.gz http://sourceforge.net/projects/libusb/files/libusb-0.1%20%28LEGACY%29/ 可以生成usb.h，新版本貌似改名为libusb.h了。

1. ./configure

2. make

3. make install(需要root 权限）

configure的详细介绍：

administrator@ubuntu:~/下载/libusb-1.0.9$ ./configure --help
`configure' configures libusb 1.0.9 to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print `checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for `--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or `..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [/usr/local]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc.  You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/libusb]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

Program names:
  --program-prefix=PREFIX            prepend PREFIX to installed program names
  --program-suffix=SUFFIX            append SUFFIX to installed program names
  --program-transform-name=PROGRAM   run sed PROGRAM on installed program names

System types:
  --build=BUILD     configure for building on BUILD [guessed]
  --host=HOST       cross-compile to build programs to run on HOST [BUILD]

Optional Features:
  --disable-option-checking  ignore unrecognized --enable/--with options
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --enable-maintainer-mode  enable make rules and dependencies not useful
              (and sometimes confusing) to the casual installer
  --enable-silent-rules          less verbose build output (undo: `make V=1')
  --disable-silent-rules         verbose build output (undo: `make V=0')
  --disable-dependency-tracking  speeds up one-time build
  --enable-dependency-tracking   do not reject slow dependency extractors
  --enable-shared[=PKGS]  build shared libraries [default=yes]
  --enable-static[=PKGS]  build static libraries [default=yes]
  --enable-fast-install[=PKGS]
                          optimize for fast installation [default=yes]
  --disable-libtool-lock  avoid locking (might break parallel builds)
  --enable-timerfd        use timerfd for timing (default auto)
  --disable-log           disable all logging
  --enable-debug-log      enable debug logging (default n)
  --enable-examples-build build example applications (default n)

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-pic              try to use only PIC/non-PIC objects [default=use
                          both]
  --with-gnu-ld           assume the C compiler uses GNU ld [default=no]

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  CPP         C preprocessor

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
