【问题】
折腾：
【记录】Ubuntu下用crosstool-ng为xscale建立交叉编译器arm-xscale-linux-gnueabi-gcc
期间，编译出错：

【解决过程】
1.参考：
How To: Build a Custom Toolchain Using Crosstool-ng
去搜一把：
crifan@ubuntu:~/develop/crosstool-ng/crosstool-ng-1.18.0_build/.build/src/linux-custom/scripts$ apt-cache search expat expat - XML parsing C library - example application libexpat1 - XML parsing C library - runtime library libexpat1-dev - XML parsing C library - development kit libneon27 - HTTP and WebDAV client library libneon27-gnutls - HTTP and WebDAV client library (GnuTLS enabled) libxml-parser-perl - Perl module for parsing XML files libxml-sax-expat-perl - Perl module for a SAX2 driver for Expat (XML::Parser) libxml-sax-perl - Perl module for using and building Perl SAX2 XML processors lib64expat1 - XML parsing C library - runtime library (64bit) lib64expat1-dev - XML parsing C library - development kit (64bit) libexpat-gst - Expat bindings for GNU Smalltalk libexpat-ocaml - OCaml expat bindings libexpat-ocaml-dev - OCaml expat bindings libidzebra-2.0-mod-grs-xml - IDZebra filter grs.xml (XML filter) libnode-node-expat - fast XML parser library for Node libnode-node-xmpp - idiomatic XMPP library for Node libxml-rss-libxml-perl - module for creating, parsing, updating RSS files with XML::LibXML libxml-sax-expat-incremental-perl - XML::SAX::Expat subclass for non-blocking (incremental) parsing libxml-sax-expatxs-perl - Perl SAX 2 XS extension to Expat parser ruby-xmlparser - Ruby interface for the expat XML parser toolkit slang-expat - S-Lang bindings for the expat XML parser tdom - A fast XML/DOM/XPath/XSLT extension for Tcl written in C tdom-dev - A fast XML/DOM/XPath/XSLT extension for Tcl written in C - development files texlive-latex-extra - TeX Live: LaTeX supplementary packages freebsd-glue - Emulate a FreeBSD build environment liblua5.1-expat-dev - Transitional package for lua-expat-dev liblua5.1-expat0 - Transitional package for lua-expat lua-expat - libexpat bindings for the Lua language lua-expat-dev - libexpat development files for the Lua language node-node-expat - fast XML parser library for Node node-node-xmpp - idiomatic XMPP library for Node crifan@ubuntu:~/develop/crosstool-ng/crosstool-ng-1.18.0_build/.build/src/linux-custom/scripts$
2.然后再去安装那个libexpat1-dev：
crifan@ubuntu:~/develop/crosstool-ng/crosstool-ng-1.18.0_build/.build/src/linux-custom/scripts$ sudo apt-get install libexpat libexpat1 libexpat1-dev libexpat-gst libexpat-ocaml libexpat-ocaml-dev crifan@ubuntu:~/develop/crosstool-ng/crosstool-ng-1.18.0_build/.build/src/linux-custom/scripts$ sudo apt-get install libexpat1-dev Reading package lists...

3.然后回去继续编译，就可以了。
【总结】
当编译crosstool-ng出现：
| [ERROR] configure: error: expat is missing or unusable |
的错误时，去安装缺失的expat库：libexpat1-dev，即可：
sudo apt-get install libexpat1-dev
