libharu, how to compile (undefined reference to)

[Igor Yalovecky]

g++ /usr/local/lib/libhpdf.a /usr/local/lib/libhpdf.so pdf.cpp

gives me:

pdf.cpp.text+0xb7): undefined reference to `HPDF_New'
pdf.cpp.text+0xf9): undefined reference to `HPDF_Free'
pdf.cpp.text+0x10f): undefined reference to `HPDF_AddPage'
.....

ok, eventually i compiled it with "gcc pdf.cpp -lhpdf -lpng -lz -lm"

but now it says:
./a.out: error while loading shared libraries: libhpdf-2.2.1.so: cannot open shared object file: No such file or directory

even after i copied this file into current dir((
