回帖：to38楼，make: 没有什么可以做的为 `first' 是因为重复configure了，make clean一下就不提示了。
是找不到目标机器的大小端，在configure的选项里加入-little-endian就行了。总之一句话，缺啥补啥。附qt-embedded-4.5.1和qt-x11-4.5.1的配置选项：

Installation options:
These are optional, but you may specify install directories.
-prefix ...... This will install everything relative to
(default /usr/local/Trolltech/QtEmbedded-4.5.1)
-hostprefix .. Tools and libraries needed when developing
applications are installed in . If is
not given, the current build directory will be used.
* -prefix-install .... Force a sandboxed "local" installation of
Qt. This will install into
/usr/local/Trolltech/QtEmbedded-4.5.1, if this option is
disabled then some platforms will attempt a
"system" install by placing default values to
be placed in a system location other than
PREFIX.
You may use these to separate different parts of the install:
-bindir ......... Executables will be installed to
(default PREFIX/bin)
-libdir ......... Libraries will be installed to
(default PREFIX/lib)
-docdir ......... Documentation will be installed to
(default PREFIX/doc)
-headerdir ...... Headers will be installed to
(default PREFIX/include)
-plugindir ...... Plugins will be installed to
(default PREFIX/plugins)
-datadir ........ Data used by Qt programs will be installed to
(default PREFIX)
-translationdir . Translations of Qt programs will be installed to
(default PREFIX/translations)
-sysconfdir ..... Settings used by Qt programs will be looked for in
(default PREFIX/etc/settings)
-examplesdir .... Examples will be installed to
(default PREFIX/examples)
-demosdir ....... Demos will be installed to
(default PREFIX/demos)
You may use these options to turn on strict plugin loading.
-buildkey .... Build the Qt library and plugins using the specified
.When the library loads plugins, it will only
load those that have a matching key.
Configure options:
The defaults (*) are usually acceptable. A plus (+) denotes a default value
that needs to be evaluated. If the evaluation succeeds, the feature is
included. Here is a short explanation of each option:
*-release ........... Compile and link Qt with debugging turned off.
-debug ............. Compile and link Qt with debugging turned on.
-debug-and-release . Com
