面对交叉编译maliit框架源代码中的问题。

inputcontextdbusaddress.cpp: In member function 'virtual void Maliit::InputContext::DBus::DynamicAddress::get()':
inputcontextdbusaddress.cpp:50: error: 'QDBusMessage' was not declared in this scope
inputcontextdbusaddress.cpp:50: error: expected ';' before 'message'
inputcontextdbusaddress.cpp:52: error: 'message' was not declared in this scope
inputcontextdbusaddress.cpp:54: error: 'QDBusConnection' has not been declared
inputcontextdbusaddress.cpp: In member function 'void Maliit::InputContext::DBus::DynamicAddress::successCallback(const QDBusVariant&)':
inputcontextdbusaddress.cpp:62: error: invalid use of incomplete type 'const struct QDBusVariant'
inputcontextdbusaddress.h:21: error: forward declaration of 'const struct QDBusVariant'
inputcontextdbusaddress.cpp: In member function 'void Maliit::InputContext::DBus::DynamicAddress::errorCallback(const QDBusError&)':
inputcontextdbusaddress.cpp:67: error: invalid use of incomplete type 'const struct QDBusError'

已经检查了循环依赖，它也包括QDBus。每件事看起来都不错。如果有人遇到此类问题，请让我知道或分享您的想法我们如何解决此问题

我自己解决了这个问题。问题来了，因为没有启用QtDBus模块。要启用QtDBus模块，您需要使用-dbus

运行configure

./ configure -embedded arm -xplatform qws / linux-powerpc-g ++ -dbus ......

但是在启用之前你应该有libdbus-1，否则你会得到以下消息。

无法启用QtDBus模块，因为找不到libdbus-1版本0.93。打开详细消息（-v）到./configure以查看最终报告。如果您认为此消息有误，则可以使用继续切换（ - 继续）到./configure继续。

为此你应该下载dbus-1.2.4.6.tar.gz和expat-2.0.1.tar.gz

交叉编译expat
- tar zxvf expat-2.0.1.tar.gz
- cd expat-2.0.1 /
- ./ configure --host = powerpc-linux --prefix = / usr / local / expat / CC = powerpc-linux-gcc
- 使;
- make install
交叉编译dbus
- tar zxvf dbus-1.2.24.tar.gz
- cd dbus-1.2.24
- ./ configure --prefix = / usr / local / dbus / --host = powerpc-linux --with-x = no ac_cv_have_abstract_sockets = yes＆＃34; CC = powerpc-linux-gcc -I / usr / local / expat / include -L / usr / local / expat / lib＆＃34;
- 使;
- make install;
用dbus交叉编译Qt
- export PKG_CONFIG_PATH = / usr / local / dbus / lib / pkgconfig
- 配置＆＃34; -dbus＆＃34;和＆＃34; -force-pkg-config＆＃34;
