用的软件包 是 mini2440自己带的 光碟的
系统 Fedora9
有一个 thread多线程的例子 我在x86的qfvb上已经编译成功且能显示
然后用arm的编译后也通过，但移植到版上不能运行
arm 多线程的编译是
多线程编译
1. 按照手册上的步骤，用“build”或者"build-all"脚本做一次完整的qtopia 2.2.0的编译；
Cp lib 将lib 备份
2. 在解压出来的qtopia-2.2.0-FriendlyARM目录下执行
$source setQteEnv
3. 进入qtopia-2.2.0-FriendlyARM/qt2目录，清除之前编译生成的文件然后手动配置qt embedded以支持multi-thread:
$cd qt2
$make clean
$echo yes |./configure -embedded -no-xft -qconfig qpe -depths 16,32 -system-jpeg -gif -thread
注意：上面configure后的参数是我自己的配置，可能与你的不同。configure之后的参数应该与你自己x86-qtopia或者arm-qtopia目录下的“build“脚本里的”echo yes | ./configure -qte“之后的参数保持一致， 只是在最后加上"-thread"
4. 上面的步骤执行后会在当前目录下产生src-mt.mk文件，用编辑器将其内容的最后一行”cd src; $(MAKE) clean“删除或注释掉；
5修改将qt2/src/tools/qtextcodec.cpp改成下面的
2148-2180行
#define QT_NO_EUCJPCODEC
#ifndef QT_NO_EUCJPCODEC
(void)new QEucJpCodec;
#endif
#define QT_NO_SJISCODEC
#ifndef QT_NO_SJISCODEC
(void)new QSjisCodec;
#endif
#define QT_NO_JISCODEC
#ifndef QT_NO_JISCODEC
(void)new QJisCodec;
#endif
#define QT_NO_EUCKRCODEC
#ifndef QT_NO_EUCKRCODEC
(void)new QEucKrCodec;
#endif
#define QT_NO_GBKCODEC
#ifndef QT_NO_GBKCODEC
(void)new QGbkCodec;
#endif
#define QT_NO_BIG5CODEC
#ifndef QT_NO_BIG5CODEC
(void)new QBig5Codec;
#endif
#define QT_NO_RTLCODEC
#ifndef QT_NO_RTLCODEC
(void)new QArabicCodec;
(void)new QHebrewCodec;
#endif
#define QT_NO_TSCIICODEC
#ifndef QT_NO_TSCIICODEC
(void)new QTsciiCodec;
#endif
6. 编译libqte-mt
$make src-mt
编译完成后将在qtopia-2.2.0- FriendlyARM/qtopia/lib目录下生成所期待的libqte-mt.so.*文件。用nm命令可以看到现在qt embedded中就已经加入了QThread支持
Cp libqte。So*
然后将lqte lqtopia lqtoia2 从备份中拷贝会来lib
在编译的时候 。pro中加入CONFIG +=thread
在Makefile中 LIBS 加入 lqte lqtoia2
编译没有警告和错误 下面是 make。log
