error: undefined reference to `get_crc_table’

I was facing these errors:

: undefined reference to `get_crc_table'
: undefined reference to `inflate'
: undefined reference to `crc32'
: undefined reference to `deflate'
: undefined reference to `deflateInit2_'
: undefined reference to `inflateEnd'
: undefined reference to `deflateEnd'
: undefined reference to `inflateInit2_'

I just fixed it adding “-lz” to end of gcc command line.
