如何对libxml2-2.6.30进行最小编译?
我需要使用libxml2对xml进行解析, 在对libxml2进行编译后将.so和.h烧进单板中，但是现在flash不够大了，只有100多KB的大小，我编译libxml2时，执行./configure --help看到有一些参数。
[w191@atp2 libxml2-2.6.30]$ ./configure --help
`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]
--libexecdir=DIR program executables [EPREFIX/libexec]
--datadir=DIR read-only architecture-independent data [PREFIX/share]
--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]
--infodir=DIR info documentation [PREFIX/info]
--mandir=DIR man documentation [PREFIX/man]
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-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--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-ipv6[=yes/no] enables compilation of IPv6 code [default=yes]
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-gnu-ld assume the C compiler uses GNU ld [default=no]
--with-pic try to use only PIC/non-PIC objects [default=use
both]
--with-tags[=TAGS]
include additional configurations [automatic]
--with-c14n add the Canonicalization support (on)
--with-catalog add the Catalog support (on)
--with-debug add the debugging module (on)
--with-docbook add Docbook SGML support (on)
--with-fexceptions add GCC flag -fexceptions for C++ exceptions (off)
--with-ftp add the FTP support (on)
--with-history add history support to xmllint shell(off)
--with-html add the HTML support (on)
--with-html-dir=path path to base html directory, default
$datadir/doc/html
--with-html-subdir=path directory used under html-dir, default
$PACKAGE-$VERSION/html
--with-http add the HTTP support (on)
--with-iconv[=DIR] add ICONV support (on)
--with-iso8859x add ISO8859X support if no iconv (on)
--with-legacy add deprecated APIs for compatibility (on)
--with-mem-debug add the memory debugging module (off)
--with-minimum build a minimally sized library (off)
--with-output add the serialization support (on)
--with-pattern add the xmlPattern selection interface (on)
--with-push add the PUSH parser interfaces (on)
--with-python[=DIR] build Python bindings if found
--with-reader add the xmlReader parsing interface (on)
--with-readline=DIR use readline in DIR
--with-regexps add Regular Expressions support (on)
--with-run-debug add the runtime debugging module (off)
--with-sax1 add the older SAX1 interface (on)
--with-schemas add Relax-NG and Schemas support (on)
--with-schematron add Schematron support (on)
--with-threads add multithread support(on)
--with-thread-alloc add per-thread memory(off)
--with-tree add the DOM like tree manipulation APIs (on)
--with-valid add the DTD validation support (on)
--with-writer add the xmlWriter saving interface (on)
--with-xinclude add the XInclude support (on)
--with-xpath add the XPATH support (on)
--with-xptr add the XPointer support (on)
--with-modules add the dynamic modules support (on)
--with-zlib[=DIR] use libz in DIR
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>
CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
headers in a nonstandard directory <include dir>
CPP C preprocessor
CXX C++ compiler command
CXXFLAGS C++ compiler flags
CXXCPP C++ preprocessor
F77 Fortran 77 compiler command
FFLAGS Fortran 77 compiler flags
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
有一个选项是--with-minimum build a minimally sized library (off)，我选择这个参数进行最小编译，但是生成的.so还是太大了，有600多KB，我的问题就是大家知道如何进行更小的编译吗，这个开源库有很多功能，但是我只需要解析xml的部分，如何编译才能保证生成大约100KB的.so文件呢。
或者有没有其他好的开源库，能够解析xml的，并且支持德文解析，支持<![data] 这种格式的。
[解决办法]
使用-Os编译
configure同时加入 --enable-ipv6=no
然后把最终的so strip一下
[解决办法]
try expat
