交叉编译库时所最常用到的配置

一般编译都是：

./configure xxx

make

make install

此处，对于./configure的xxx，我最常用的是：

1	`.` `/configure` `--prefix=YOUR_INSTALL_PATH --build=CURRENT_ENV --target=CROSS_COMPILER --host=CROSS_COMPILER CC=CROSS_COMPILER-gcc OTHER_PARAMETER`

其中：

–prefix=YOUR_INSTALL_PATH

即，你所要把当前的库，在编译完毕之后，安装到哪里

如：

1	`.` `/configure` `--prefix=` `/opt/crosscompile/xmlrpc` `--build=i686-pc-linux-gnu --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi CC=arm-xscale-linux-gnueabi-gcc`

–build=CURRENT_ENV

目前我遇到的有两种：

一个是cygwin：

–build=i686-pc-cygwin

如：

1	`.` `/configure` `--prefix=$HOME` `/develop/crosstool-ng/x-tools/armxscaleexpat` `--build=i686-pc-cygwin --target=arm-xscale-linux --host=arm-xscale-linux CC=arm-xscale-linux-gnueabi-gcc`

一个是普通的Linux，比如Ubuntu：

–build=i686-pc-linux-gnu

如

1	`.` `/configure` `--prefix=` `/opt/crosscompile/curl` `--build=i686-pc-linux-gnu --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi CC=arm-xscale-linux-gnueabi-gcc --` `enable` `-static`

关于其值的来历：

（1）其中，此build的值，我之前是参考：

之前编译时的输出：

 
        [EXTRA]  Dumping internal crosstool-NG configuration
       
        [EXTRA]    Building a toolchain 
        for
        :
       
        [EXTRA]      build  = i686-pc-cygwin
       
        [EXTRA]      host   = i686-pc-cygwin
       
        [EXTRA]      target = arm-xscale-linux-gnueabi

而知道的。

（2）其中，此处的build的值，也是参考：

 
        [EXTRA]  Dumping internal crosstool-NG configuration
       
        [EXTRA]    Building a toolchain 
        for
        :
       
        [EXTRA]      build  = i686-pc-linux-gnu
       
        [EXTRA]      host   = i686-pc-linux-gnu
       
        [EXTRA]      target = arm-xscale-linux-gnueabi

才知道的。

–target=CROSS_COMPILER和–host=CROSS_COMPILER

对于target和host，此处，都是设置的是交叉编译器的（前缀）。

比如，如果你的交叉编译器是arm-linux，那就是：

1	`--target=arm-linux --host=arm-linux`

我此处，用crosstool-ng编译出来的for xscale的交叉编译器是：arm-xscale-linux-gnueabi

所以，此处后续编译各种库，都是用的是：

1	`--target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi`

举例：

1	`.` `/configure` `--prefix=$HOME` `/develop/crosstool-ng/x-tools/armxscalelog4c` `--build=i686-pc-cygwin --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi --with-expat-prefix=$HOME` `/develop/crosstool-ng/x-tools/armxscaleexpat` `CC=arm-xscale-linux-gnueabi-gcc`

如：

1	`.` `/configure` `--prefix=` `/opt/crosscompile/curl` `--build=i686-pc-linux-gnu --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi CC=arm-xscale-linux-gnueabi-gcc --` `enable` `-static`

CC=CROSS_COMPILER-gcc

1.此处的CC参数，是用于指定编译器用哪个。

一般都是对应的交叉编译器的前缀，加上gcc，比如：

arm-linux的话，加上gcc就是：arm-linux-gcc

arm-xscale-linux-gnueabi加上gcc，就是：arm-xscale-linux-gnueabi-gcc

2.而且，也多数都是可以在./configure时，就设置好对应的CC的值的。

如：

1	`.` `/configure` `--prefix=` `/opt/crosscompile/curl` `--build=i686-pc-linux-gnu --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi CC=arm-xscale-linux-gnueabi-gcc --` `enable` `-static`

之后，直接去make即可。

但是也有例外：

有时，由于configure不支持设置CC，所以需要放到后面的make才行，即：

1 2	`.` `/configure` `--prefix=$HOME` `/develop/crosstool-ng/x-tools/libcgi` `--build=i686-pc-cygwin --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi` `make` `CC=arm-xscale-linux-gnueabi-gcc`

OTHER_PARAMETER

1../configure可以去添加你所需要的参数

但是一般都支持的规则是：

–enable-xxx：启用（编译）某个子模块或功能（feature）

–disable-xxx：禁止（不编译）某个子模块或功能（feature）

–with-xxx：类似于–enable-xxx

–without-xxx：类似于–disable-xxx

经过调试错误，发现就不需要编译python，所以，可以去添加对应的

--without-python

去禁止编译python。

所用的配置就是：

1	`.` `/configure` `--prefix=` `/opt/crosscompile/libxml2` `--build=i686-pc-linux-gnu --target=arm-xscale-linux-gnueabi --host=arm-xscale-linux-gnueabi CC=arm-xscale-linux-gnueabi-gcc --without-python`

2.添加参数之前，需要搞清楚，当前你所要去编译的库，本身支持什么参数。

正常都是可以通过：

1	`.` `/configure` `--help`

去查看到，当前模块，所支持哪些参数。

`configure' configures this package 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]

  --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]

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.

Report bugs to the package provider.
