我正在尝试借助 python 的 cdsapi 模块检索数据。但给出了以下错误

    2020-10-19 12:55:52,780 INFO Sending request to https://cds.climate.copernicus.eu/api/v2/resources/reanalysis-era5-press

我有以下c程序

#include <stdio.h>

int main() 
{
    printf("hello');
    return 0;
}

当我编译这个文件

gcc -c rr2.c

然后使用带有共享选项的链接器

/ld-new -shared    -o tmpdir/dump rr2.o 

它给出以下错误

rr2.o:在创建共享对象时,不能使用针对`.rodata'的重定位R_X86_64_32; 用-fPIC重新编译

我不明白为什么会出现这种错误.任何人都可以帮我理解为什么会出现这个错误？
