对“GDALAllRegister”的未定义引用

我在使用 gdal 时遇到了问题。我目前正在使用 Ubuntu，IDE 是 Eclipse CDT，我在下面给出了我的代码，并且还安装了 gdal 包，但它给出了构建错误

#include <stdio.h>
#include<unistd.h>
#include "gdal/gdal_priv.h"
#include "gdal/cpl_conv.h"
#include<gdal/gdal.h>
int main(int argc,char* argv[])
{
    void *hLib_Comm;
    char exePath[800];
    if(getcwd(exePath,sizeof(exePath))== NULL)  {
        printf("Exe path access error\n");
    }
    GDALDataset  *poDataset;

    GDALAllRegister();

    poDataset = (GDALDataset *) GDALOpen( exePath, GA_ReadOnly );
    if( poDataset == NULL )
    {
        printf("Exe path access error\n");
    }
}

根据这你没有build-essentials安装该软件包。只需运行以下命令即可解决此问题：

sudo apt-get install build-essential

我尝试运行你的代码，但是由于一些标题依赖关系而遇到了另一个问题：

gcc gdal.c
