tq2440实验手册qt编译问题

转载：http://blog.sina.com.cn/s/blog_6182b82201015ym1.html

编译qtopia最好使用的是低版本的gcc和g++. 举个简单的例子在qtopia的源代码中有个函数的使用

 

在qmemoryfile_unix.cpp中int open(const char*, int, ...),这个函数的使用就有问题了。因为open函数需要三个参数，而这里只有两个，新版本的gcc必须要求传入三个参数。所以这个会有错误。需要修个源码。。

 

还有在另外的一个文件中使用strrchr函数时，函数的第一个参数是const型的，新版本g++不支持报错了。而g++4.1编译则没有问题。所以这里我重新安装了g++4.1版本。

 

编译qtopia时候可能还会遇到问题

make[1]: Leaving directory `/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qt2/src'

解决办法：

在Ubuntu 9.10上， gcc会严格检查open()的参数传递，如果第二个参数为O_CREAT的话(就像qtopia-2.2.0-FriendlyARM/qt2/src /tools/qmemoryfile_unix.cpp的143行这样)，必须传入第三个参数mode。因此，手动修改x86-qtopia- 2.2.0/qt2/src/tools/qmemoryfile_unix.cpp 143行

将

    if (!f)

        f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY);   

修改为

    if (!f)

        f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY, 0666);
