嵌入式linux开发，交叉编译qt4.8.5报错：Makefile:1054: recipe for target ‘.moc/release-shared-emb-arm/moc_qabstract

一、问题描述。

嵌入式linux开发，交叉编译qt4.8.5，执行make时报错如下：

二、问题分析。

查看bin文件夹下的内容，新生成的文件有 moc、qmake、rcc、uic 四个文件。

ms@ubuntu:~/work/code/qt/opensource/qt-everywhere-opensource-src-4.8.5$

 分别查看四个文件属性，发现编译的部分文件为arm下的执行文件，生成的四个新文件应都为x86下的可执行文件。

ms@ubuntu:~/work/code/qt/opensource/qt-everywhere-opensource-src-4.8.5$ file ./bin/moc
./bin/moc: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.3, for GNU/Linux 2.6.16, not stripped
ms@ubuntu:~/work/code/qt/opensource/qt-everywhere-opensource-src-4.8.5$ file ./bin/qmake

三、解决方案。

1、研究调整配置，未解决，配置如下：

./configure \
 -prefix /home/ms/work/product/ok335xD/tool/toolchain/qt4.8.5 \
 -release \
 -opensource \
 -shared \
 -fast \
 -qt-sql-sqlite \
 -no-qt3support \
 -no-phonon \
 -webkit \
 -platform qws/linux-x86_64-g++ \
 -no-mmx \
 -no-3dnow \
 -no-sse \
 -no-sse2 \
 -I/usr/local/arm/tslib/include \
 -L/usr/local/arm/tslib/lib \
 -qt-zlib \
 -no-libtiff\
 -qt-libtiff \
 -qt-libpng \
 -no-libmng \
 -qt-libmng \
 -no-libjpeg \
 -qt-libjpeg \
 -no-openssl \
 -nomake docs \
 -optimized-qmake \
 -no-nis \
 -no-cups \
 -pch \
 -no-separate-debug-info \
 -embedded arm \
 -xplatform qws/linux-arm-g++ \
 -little-endian \
 -host-little-endian \
 -qt-freetype \
 -depths 16,18,24,32 \
 -qt-gfx-linuxfb \
 -qt-gfx-transformed \
 -qt-kbd-linuxinput \
 -qt-mouse-linuxinput \
 -qt-mouse-tslib \
 -no-glib \
 \
 -confirm-license \
 -no-opengl \
 -no-qvfb 
# -verbose

2、一天后，执行清除，去掉arm平台相关的两个参数，未解决，吐血。

make clean
make confclean

 -embedded arm \
 -xplatform qws/linux-arm-g++ \

3、一天后，更换交叉编译器，执行清除后编译，问题依旧。查看moc文件夹下相关文件，Makefile文件日期不变。最终确定，执行清除未能删除Makefile文件，删除源码，重新解压和配置，问题解决。

4、经确认，没有生成新 Makefile 文件的原因是使用了 -fast 参数，应用使用 -no-fast 。
