解决方案1：在cpp文件中放置.c，且在该文件中引用变量

解决方案2：在一个cpp文件中包含.c，但在另一个cpp文件中使用结构体变量

cpp文件2

#include "dialog3.h"

#include <QDebug>

extern "C"

{

    typedef struct PRINT

    {

        unsigned char Parameters;//BitDepthAC,BitDepthDC,q

        unsigned char PlaneCodes;//指定段的某一个位平面所有的码流

        unsigned char PlaneCodesSeparate;//指定段某个位平面的所有码流，不同的码字是分开的

        unsigned char PlaneIndex;

        unsigned char PlaHit;

        unsigned char AllCodesPrint;//所有的码流，并行，串行

        unsigned short SegIndex;

        unsigned char SegHit;

        unsigned int BlockIndex;

        unsigned char BlockHit;

        unsigned char BlockScanPrint;//指定段中某个块的扫描字

        unsigned char Option;

        unsigned char WordToCode;

        unsigned char BlockCodes;//single block

        unsigned char GagHit;

        unsigned int GagIndex;

        unsigned char BlockBeforeScan;

        unsigned char Header;

        unsigned char DC_DPCM;

        unsigned char DC_RiceCodes;

        unsigned char AC_Depth_DPCM;

        unsigned char AC_DepthRiceCodes;

        unsigned char DC_Additional;

        unsigned char DC_Refinement;

        unsigned char Stage1;

        unsigned char Stage2;

        unsigned char Stage3;

        unsigned char Stage4;

        unsigned char DWT_PRINT;

        unsigned char IDWT_PRINT;

        unsigned char PlaneTime_Print;

        unsigned char ScanTime_Print;

    }PrintPara; 

    extern PrintPara Print;

}

Dialog3::Dialog3(QWidget *parent)

    : QDialog(parent)

{

    ui.setupUi(this);

    ui.checkBox_3->setChecked(true);

    ui.checkBox_4->setChecked(true);

}

不知道是什么原因，但是实验证明可行
