Whoever compile qtiplot-0.9.8.9 in Fedora 18?

I just installed Fedora 18 DVD.iso using flash disk.
I want to compile qtiplot, bu I can't understand C++ language (I use Fortran).
who can resolve the following problems in compilation processes.

I have resolved the last two problems and encounter the new problems:


/usr/bin/ld: ../tmp/qtiplot/minigzip.o: undefined reference to symbol 'gzclose'
/usr/bin/ld: note: 'gzclose' is defined in DSO /lib64/libz.so.1 so try adding it to the linker command line
/lib64/libz.so.1: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
