Hi Beatriz, hi all, in addition to Mattia's and zyx' posts:
Messages beginning with "undefined reference to" are frequently also linker error messages. To correct the error(s), it is then necessary to provide the correct library name and path specifications to the compiling/building environment/program in use. For example for GNU GCC in a shell (command line) it is (for PoDoFo) the option -lpodofo to give the library name and -L/path/to where "/path/to" has to be replaced by the path where the libpodofo.so library (symlink) is located (not required when libpodofo has been installed from a package, for default-repository ones at least).
