question about compile flags

Hi
Im new C++ programmer. I've got question how to compile Exiv2 examples under linux? which flags I should use to compile it? I added flag -lexiv2 but it does not work - got a lot of errors:
/usr/lib/gcc/i486-linux-gnu/4.4.3/../../../../lib/libexiv2.a(pngchunk.o)||In function `Exiv2::Internal::PngChunk::zlibUncompress(unsigned char const*, unsigned int, Exiv2::DataBuf&)':|
(.text+0x79)||undefined reference to `uncompress'|
/usr/lib/gcc/i486-linux-gnu/4.4.3/../../../../lib/libexiv2.a(pngchunk.o)||In function `Exiv2::Internal::PngChunk::zlibCompress(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)':|

Thanks!

See the README, samples/Makefile and the output of "make samples". It is recommended to use the pkg-config utility to help you get the right options for your environment and exiv2 configuration. (The errors in your example are probably caused by a missing -lz.)
