巨大なプロジェクトを Qt4.x から Qt5 に移行しています。現在、私は解決できないこの問題を抱えています：

C:\Qt5\5.2.1\mingw48_32\lib/libQt5Core.a(d003170.o):(.text+0x0): multiple definition of `QString::fromUtf8(char const*, int)'

いくつかのインクルードが重複しているに違いないことは知っていますが、プロジェクトが非常に大きいため、それを見つける方法がわかりません。それは奇妙QStringです。デフォルトで追加されているため、何もする必要はないと思いますインクルードまたは何かの。この同じ問題についてウェブで検索しましたが、どうやらそれについては何もありません。含まれるものは次のとおりです。

aisinfowidget.cpp:

#include "aisinfowidget.h"
#include "appcommon.h"
#include "shipdata.h"
#include "messagebox.h"
#include "touchswibz.h"
#include "customwidgets.h"
#include "riskwidget.h"
#include "aisradarmodule.h"
#include "mapmodulelist.h"
#include "eventswidget.h"

#include <HDP.h>

#include <QTextTable>
#include <QDesktopServices>
#include <QUuid>
#include <QUrlQuery>

gpssettingswidget.cpp (ここから未定義の参照が来ます)

#include "gpssettingswidget.h"
#include "gpsmodule.h"

#include <QtSerialPort/QSerialPort>
#include <QtSerialPort/QSerialPortInfo>
#include "QtSerialPort/qserialportglobal.h"
#include "QtSerialPort/qserialportinfo.h"
//#include <qextserialenumerator.h>

#include <QLineEdit>
#include <QtDebug>

そして、ここに私の.proファイルがあります:

ご覧のとおり、serialport を QT 変数に追加し、ライブラリをリンクしたので、未定義の参照の理由がわかりません。QString の多重定義を解決すると、これらの問題が解決する可能性があります。誰かが私を正しい方向に向けてくれることを願っています。

どうもありがとうございました。

PS: コードは私のものではないため、問題を見つけるのがさらに難しくなっています。

ライブラリへのリンケージと gpssettingswidget.cpp のすべてのインクルードにコメントを付けてみましたが、同じ未定義の参照エラーが発生しました。それでも多重定義エラーの可能性があります。私がそれを解決するまで、私は他のものを確信することはできません.

どうやら、これによると、 Qt5では追加するだけです

#include <QtSerialPort/QtSerialPort>

ファイルで、QT += serialport で .pro ファイルですが、それでも同じエラーが発生します。コンパイラが何らかの形でライブラリを見つけることができないと確信していますが、他に何をすべきかわかりません。また、Qt4 または Qt5 でコンパイルされたライブラリを使用する必要があるかどうかもわかりません。
私は両方を試しましたが、同じエラーが何度も発生しました。

編集 3 いいね！

千の異なる方法でコンパイルした後、エラーを解決することができましQtSerialPortた.未定義の参照を解決したファイルを取得しました. *

もっと。

最終編集

Qxmpp ライブラリについても同じことを行い、これらの厄介なエラーをすべて解決しました。現在、他のエラーがありますが、その時点を過ぎたので、質問は回答済みであると言えます。どうもありがとうございました。

サードパーティのライブラリQtSerialPortとQextSerialPort. 幸運なことに、私は最近、この 2 人の素敵な男と格闘してきました。

QString::fromUtf8「おそらく」エラーは、QStringLiteralで定義され たマクロから発生しますqserialportglobal.h

#ifndef QStringLiteral
#define QStringLiteral(str) QString::fromUtf8(str)
#endif

PS私はQt 4.8.5を使用していますが、多少の違いがあるかもしれません。

gpssettingswidget.cppには に含まれているため、再度含める必要はありません。qserialportglobal.hQSerialPort

インクルージョンを削除して、改善されるかどうかを確認してください。これらの複数のエラーに対処するのは骨の折れる作業であることはわかっています。この回答は最終的な解決策ではありません。

少なくとも何が変わるかを見て、ここで議論することができます.

[編集] あなたも使っているのを見ましたが、と を一緒Qwtに使うときに問題がありました。問題はここにありますが、まだ解決されていません。に移行することで競合を回避しました。ライブラリの競合があるかもしれませんが、私は疑います。QwtQtSerialPortQextSerialPort
