[Gdal-dev] why I can't use the method CSVGetField()?

[lky]

Hello,everyone:
    I use the method to read ellipsoid data from "data\ellipsoid.csv".I include the "cpl_csv.h",but there are so many build error after I include the header file.

so I have two questions:
1.Why I can't use the method CSVGetField()?
2.If I want to read the ellipsoid data from "data\ellipsoid.csv", how I can do?

Thanks a lot
