Re:回 8楼(kasim) 的帖子

高手，怎么“这可以通过在qte的配置上加上'-thread'参数做到”做才能有效果，能够在详细点吗？谢谢了，我这个问题纠结了很久。谢谢了

由于qtopia 2.2.0的makefile里的问题，你现在只能自己手动编译出支持thread的libqte-mt.so. 具体做法如下:

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；

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configure之后的参数与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. 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：

alex@aling-xw4400:~/x86-qtopia/qtopia-2.2.0-FriendlyARM/qt2$ nm ../qtopia/lib/libqte-mt.so.2.3.12 |grep -i QThread
0015deb0 t _GLOBAL__I_qthread_unix.cpp

好贴！！！！   

加精

对不起字体太大不好看了。

你需要在命令行上加上"-lpthread"来链接libpthread.so

引用第24楼kasim于2010-05-07 14:57发表的  :

应该加了"lpthread"的。我用的./build命令内容如下：
source /opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/setQpeEnv
qmake -o Makefile -spec /opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/mkspecs/qws/linux-generic-g++ *.pro
make clean
make

在路径/opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/mkspecs/qws/linux-generic-g++ 下找到qmake.conf 部分内容如下：
QMAKE_CC                = gcc
QMAKE_LEX               = flex
QMAKE_LEXFLAGS          =
QMAKE_YACC              = yacc

QMAKE_CFLAGS_SHLIB      = -fPIC
QMAKE_CFLAGS_YACC       = -Wno-unused -Wno-parentheses

QMAKE_LIBS_QTOPIA       = -lqtopia2 -lqtopia -lqpe
QMAKE_LIBS_THREAD       = -lpthread

QMAKE_MOC               = $(QTDIR)/bin/moc
这个里面加了你说的这个啊。我不知道你说的这个要在什么命令行里加？
    

不管qmake.conf里面定义了什么，只有实际加到gcc, g++命令行上的参数才有意义。为什么不回头再看一眼g++实际调用的命令行呢？

我的理解是g++带的参数选项命令是在qmake.conf定义好的。不是我手动加上去的。我现在找不到方法如何设置才能在g++实际调用中加上-lpthread。能否给个指引啊？万分感谢！

我的理解是g++带的参数选项命令是在qmake.conf定义好的

如果是这样的话，那qmake.conf里的定义应该会在某个Makefile里调用，去把它找出来，然后看看为什么QMAKE_LIBS_THREAD没有被用到。
