Linux下的软件安装
Linux下，获得了一个软件的源代码后，最常见的软件安装步骤如下：
1 ./configure （自动配置各种参数、默认特性等）
2 make （编译源代码，生成可执行程序/工具）
3 make install （将生成的工具安装/拷贝到对应的目录，比如/usr/bin，下）
4 make clean （卸载，删除对应的工具）
另外，对于在configure的时候，支持哪些特性设置和参数传递，常见的可以用：
./configure –help
去查看，比如，对于我此处的 lrzsz-0.12.20，就有：
——————————————————————————————————–
[crifan@localhost lrzsz-0.12.20]$ ./configure –help
Usage: configure [options] [host]
Options: [defaults in brackets after descriptions]
Configuration:
–cache-file=FILE cache test results in FILE
–help print this message
–no-create do not create output files
–quiet, –silent do not print `checking…’ messages
–version print the version of autoconf that created configure
Directory and file names:
–prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local]
–exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[same as prefix]
–bindir=DIR user executables in DIR [EPREFIX/bin]
–sbindir=DIR system admin executables in DIR [EPREFIX/sbin]
–libexecdir=DIR program executables in DIR [EPREFIX/libexec]
–datadir=DIR read-only architecture-independent data in DIR
[PREFIX/share]
–sysconfdir=DIR read-only single-machine data in DIR [PREFIX/etc]
–sharedstatedir=DIR modifiable architecture-independent data in DIR
[PREFIX/com]
–localstatedir=DIR modifiable single-machine data in DIR [PREFIX/var]
–libdir=DIR object code libraries in DIR [EPREFIX/lib]
–includedir=DIR C header files in DIR [PREFIX/include]
–oldincludedir=DIR C header files for non-gcc in DIR [/usr/include]
–infodir=DIR info documentation in DIR [PREFIX/info]
–mandir=DIR man documentation in DIR [PREFIX/man]
–srcdir=DIR find the sources in DIR [configure dir or ..]
–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
Host type:
–build=BUILD configure for building on BUILD [BUILD=HOST]
–host=HOST configure for HOST [guessed]
–target=TARGET configure for TARGET [TARGET=HOST]
Features and packages:
–disable-FEATURE do not include FEATURE (same as –enable-FEATURE=no)
–enable-FEATURE[=ARG] include FEATURE [ARG=yes]
–with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
–without-PACKAGE do not use PACKAGE (same as –with-PACKAGE=no)
–x-includes=DIR X include files are in DIR
–x-libraries=DIR X library files are in DIR
–enable and –with options recognized:
–disable-timesync exclude support for timesync protocol
–enable-pubdir=/path include support for a public writeable directory
–disable-mkdir disable support for creating directories (lrz)
–enable-syslog=FACILITY,{force,default,optional} include syslogsupport
–disable-nls do not use Native Language Support
–with-included-gettext use the GNU gettext library included here
–with-catgets use catgets functions if available

其中对于想用交叉编译器，比如arm-linux-gcc，去编译用于生产目标开发板上的可执行程序/工具，可以尝试：
./configure –host=arm-linux
不过，很奇怪的是，此处暂时未能生效，寻找原因中。。。。
