configure脚本的常用参数

下面是一些常用的configure选项参数及其解释：

• --prefix=<directory>：指定安装目录
• --with-<package>：指定依赖的外部库或软件包
• --enable-<feature>：启用某个特性
• --disable-<feature>：禁用某个特性
• --enable-shared：编译生成共享库
• --enable-static：编译生成静态库
• --enable-debug：编译启用调试模式
• --disable-dependency-tracking：禁用依赖性跟踪
• --with-<package>-root=<directory>：指定外部库的根目录
• --with-<package>-include=<directory>：指定外部库的头文件目录
• --with-<package>-lib=<directory>：指定外部库的库文件目录

其中，<package>是指外部库的名称。例如，--with-openssl指定OpenSSL库，--with-zlib指定zlib库。在使用这些选项时，需要将<directory>替换为实际的目录路径。

要指定configure使用的其他库的源代码目录，可以使用以下选项：

--with-<library>=<path>

其中，<library>是你想要指定的库，<path>是库的源代码目录路径。

例如，如果您想要指定OpenSSL库的源代码目录，可以使用如下命令：

./configure --with-openssl=/usr/local/openssl

这样，configure将使用指定的目录中的OpenSSL库源代码进行编译。同样的方法也适用于其它的库。
对于libpng1.2.56的configure脚本选项：

$ ./configure --help
`configure' configures libpng 1.2.56 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]

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

  --with-sysroot[=DIR]    Search for dependent libraries within DIR (or the
                          compiler's sysroot if not specified).
  --with-pkgconfigdir     Use the specified pkgconfig dir (default is
                          libdir/pkgconfig)

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
  LT_SYS_LIBRARY_PATH
              User-defined run-time library search path.

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