在窗户中使用qt清洗

问题描述

我开始在c ++中使用rinside和rcpp。我只是想从零开始，所以我的QT项目只有创建一个RInside实例，我有一个问题，我不能解决。我在项目中只有一个对话框。

I am beginning using rinside and rcpp within c++. I just want to start from zero so my QT project has nothing but the creation of a RInside instance and I have a problem I cannot solve. I have only one dialog form in the project.

我的项目文件：

QT       += core gui

TARGET = rcpp-rinside
TEMPLATE = app


SOURCES += main.cpp\
    dialog.cpp

HEADERS  += dialog.h

FORMS    += dialog.ui


INCLUDEPATH += C:\R\R-2.15.1\include
INCLUDEPATH += C:\R\R-2.15.1\library\Rcpp\include
INCLUDEPATH += C:\R\R-2.15.1\library\RInside\include

LIBS += -LC:\R\R-2.15.1\bin\i386 -lR
LIBS += -LC:\R\R-2.15.1\library\Rcpp\lib\i386\ -lRcpp
LIBS += -LC:\R\R-2.15.1\library\RInside\lib\i386\ -lRInside

主文件：

#include <QtGui/QApplication>
#include "dialog.h"

int main(int argc, char *argv[])
{
    RInside R(argc, argv);

    QApplication a(argc, argv);

    Dialog w;

    w.show();

    return a.exec();
}

对于其他文件，没有什么，因为它只是一个空格式。
当我构建这个，我有很多错误，如下所示：

For the other files, there is nothing there because it's only an empty form.When I build this, I got a lot of errors like the following:

我使用R-2.15.1，RInside 0.2.7，Rcpp 0.9.10，QT 4.8.0，MinGW 4.6。 1。

I am using R-2.15.1, RInside 0.2.7, Rcpp 0.9.10, QT 4.8.0, MinGW 4.6.1.

推荐答案

在链接到Rcpp之前，你必须告诉链接器链接RInside。请参阅此rcpp-devel帖子。

You have to tell the linker to link against RInside before linking against Rcpp. See this rcpp-devel post.

对于qtdensity在windows下工作，您需要修改qtdensity.pro文件的第46行：

For qtdensity to work under windows, you need to modify line 46 of the qtdensity.pro file:

QMAKE_LIBS += $$RLDFLAGS $$RBLAS $$RLAPACK $$RCPPLIBS $$RINSIDELIBS

并切换$$ RCPPLIBS和$$ RINSIDELIBS的顺序：

and switch the order of $$RCPPLIBS and $$RINSIDELIBS:

QMAKE_LIBS += $$RLDFLAGS $$RBLAS $$RLAPACK $$RINSIDELIBS $$RCPPLIBS

您还必须将双引号在qtdensity.pro文件中，如上所述。这些修改将在下一版本的RInside（目前为0.2.9）。

You also have to replace single quotes with double quotes in the qtdensity.pro file, as mentioned. These modifications will be in the next version of RInside (currently 0.2.9).

此外，您必须使用相同的编译器来构建Rcpp& RInside并编译您的Qt应用程序。

In addition, you must have used the same compiler to build Rcpp & RInside and to compile your Qt application.
