firefly3588安装QGC地面站

效果视频https://live.csdn.net/v/258035
一、下载qt源码
https://download.qt.io/archive/qt/5.15/5.15.2/single/qt-everywhere-src-5.15.2.tar.xz
二、安装xcb依赖环境

sudo apt-get install '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev

三、configure

解压源码以后，进入源码目录打开终端，新建一个build文件夹，在里面再新建一个autoconfig.sh 并赋予可执行权限

../configure -recheck-all -release -extprefix "/home/firefly/Qt5.12.8" -xplatform linux-aarch64-gnu-g++ -no-opengl -no-openssl -nomake tests -no-compile-examples -nomake examples -gif -ico -qt-libpng -qt-libjpeg -qt-sqlite -opengl es2 	-xcb -xcb-xlib 	-bundled-xcb-xinput

安装qt-creator

sudo apt-get install qt5-default qtcreator -y

qt之库编译错误：qdbusmarshaller.cpp:(.text+0x0): `QDBusMarshaller::append(QString const&)'被多次定义
错误描述

.obj/qdbusmarshaller.o：在函数‘QDBusMarshaller::close()’中：

错误原因
这是由于在源码文件qtbase/src/dbus/qdbusargument.cpp中有以下代码：

// for optimization purposes, we include the marshallers here
#include "qdbusmarshaller.cpp"
#include "qdbusdemarshaller.cpp

这是已经包含了qdbusmarshaller.cpp。但是在工程文件qtbase/src/dbus/dbus.pro中同时又包含以下代码：

SOURCES += qdbusconnection.cpp \
    qdbusconnectioninterface.cpp \
    qdbuserror.cpp \
    qdbusintegrator.cpp \
    qdbusmessage.cpp \
    qdbusserver.cpp \
    qdbusabstractinterface.cpp \
    qdbusinterface.cpp \
    qdbusxmlparser.cpp \
    qdbusutil.cpp \
    qdbusintrospection.cpp \
    qdbusabstractadaptor.cpp \
    qdbusinternalfilters.cpp \
    qdbusmetaobject.cpp \
    qdbusxmlgenerator.cpp \
    qdbusmisc.cpp \
    qdbusargument.cpp \
    qdbusreply.cpp \
    qdbusmetatype.cpp \
    qdbusextratypes.cpp \
    qdbusmarshaller.cpp \
    qdbuscontext.cpp \
    qdbuspendingcall.cpp \
    qdbuspendingreply.cpp \
    qdbus_symbols.cpp \
    qdbusservicewatcher.cpp \
    qdbusunixfiledescriptor.cpp \
    qdbusvirtualobject.cpp

解决方法

可以删除qtbase/src/dbus/dbus.pro文件中SOURCES对qdbusmarshaller.cpp的引用，例如：

SOURCES += qdbusconnection.cpp \
    qdbusconnectioninterface.cpp \
    qdbuserror.cpp \
    qdbusintegrator.cpp \
    qdbusmessage.cpp \
    qdbusserver.cpp \
    qdbusabstractinterface.cpp \
    qdbusinterface.cpp \
    qdbusxmlparser.cpp \
    qdbusutil.cpp \
    qdbusintrospection.cpp \
    qdbusabstractadaptor.cpp \
    qdbusinternalfilters.cpp \
    qdbusmetaobject.cpp \
    qdbusxmlgenerator.cpp \
    qdbusmisc.cpp \
    qdbusargument.cpp \
    qdbusreply.cpp \
    qdbusmetatype.cpp \
    qdbusextratypes.cpp \
    qdbusmarshaller.cpp \				/* 手动删除本行 */
    qdbuscontext.cpp \
    qdbuspendingcall.cpp \
    qdbuspendingreply.cpp \
    qdbus_symbols.cpp \
    qdbusservicewatcher.cpp \
    qdbusunixfiledescriptor.cpp \
    qdbusvirtualobject.cpp

qt之库编译错误：qmutex_linux.cpp:multiple definition of ‘QBasicMutex::lockInternal(int)’

make: *** [module-qtbase-make_first] Error 2

错误原因
这是由于在源码文件qtbase/src/corelib/thread/qmutex.cpp中有以下代码：

#ifdef QT_LINUX_FUTEX
#  include "qmutex_linux.cpp"
#elif defined(Q_OS_MAC)
#  include "qmutex_mac.cpp"
#elif defined(Q_OS_WIN)
#  include "qmutex_win.cpp"
#else
#  include "qmutex_unix.cpp"
#endif

这是为了兼容不同平台的代码。但是在工程文件qtbase/src/corelib/thread/thread.pri中同时又包含以下代码：

SOURCES += \
   thread/qatomic.cpp \
   thread/qmutex.cpp \
   thread/qreadwritelock.cpp \
   thread/qsemaphore.cpp \
   thread/qthreadpool.cpp \
   thread/qthreadstorage.cpp

win32 {
    SOURCES += \
        thread/qmutex_win.cpp \
        thread/qwaitcondition_win.cpp
} else {
    darwin {
        SOURCES += thread/qmutex_mac.cpp
    } else: linux {
        SOURCES += thread/qmutex_linux.cpp
    } else {
        SOURCES += thread/qmutex_unix.cpp
    }
    SOURCES += thread/qwaitcondition_unix.cpp
}

这两个地方对文件qmutex_linux.cpp进行了重复包含，所以造成了在编译期间检测到两个文件中有相同的符号。
解决方法

可以删除qtbase/src/corelib/thread/thread.pri文件中SOURCES对qmutex_linux.cpp的引用，例如：

SOURCES += \
   thread/qatomic.cpp \
   thread/qmutex.cpp \
   thread/qreadwritelock.cpp \
   thread/qsemaphore.cpp \
   thread/qthreadpool.cpp \
   thread/qthreadstorage.cpp

win32 {
    SOURCES += \
    	thread/qmutex_win.cpp \    			/* 手动删除本行 */
        thread/qwaitcondition_win.cpp
} else {
    darwin {
        SOURCES += thread/qmutex_mac.cpp	/* 手动删除本行 */
    } else: linux {
        SOURCES += thread/qmutex_linux.cpp	/* 手动删除本行 */
    } else {
        SOURCES += thread/qmutex_unix.cpp	/* 手动删除本行 */
    }
    SOURCES += thread/qwaitcondition_unix.cpp
}
