[gdal-dev] gdal unresolved external symbol for"GDALFindAssociatedFile" and "GDALWriteRPBFile"

[张斌]

Hi,
  I'm using GDAL 3.2.0 from http://www.gisinternals.com/. When I build my own program, it can not link successfully.
  Here is my code:

"
#include <iostream>
#include "gdal_priv.h"
#include "gdal_mdreader.h"

int main() {

    std::string pszFilename = R"(E:\datasets\MAR\18MAR10060250-P2AS-012787451020_01_P001.TIF)";

    GDALDataset* poDataset;
    GDALAllRegister();
    poDataset = (GDALDataset*)GDALOpen(pszFilename.c_str(), GA_ReadOnly);

    CPLString m_osRPBSourceFilename = GDALFindAssociatedFile(pszFilename.c_str(), "RPB", nullptr, 0);
    char** papszRPCMD = poDataset->GetMetadata("RPC");
    if (papszRPCMD != nullptr) {
        GDALWriteRPBFile( pszFilename.c_str(), papszRPCMD );
    }

    return 0;
}
"

  The building logs is the following:
