thank you really much for all suggestions. I tried them but I have always the same problem.
After times I tried also to install boardland c++ and use the function make as in the foolowing way:
C:\Users\PC\Desktop\libharu-2.0.8>make -f script/Makefile.bcc
MAKE Version 5.0 Copyright (c) 1987, 1997 Borland International
Fatal: Unable to open makefile
But doesn't work.
In the folder script there are Makefiles with other format: bcc32, bcc32_dll, cygwin, cywin_dll, gcc, gcc_so, in, mingw, mingw_dll, msvc, msvc_dll.
In particular, If you have time to look better the files in the folder is possibile to find all files in the zip folder from the link
http://libharu.org/. But I don't want to disturb you excessively.
Until now I thank you very much for all your answers and I will continue to try to succeed.
Best regards
