The above sample program may be found in /src/main/simple examples/sample.cc in
FreeLing tarball.
Once you have compiled and installed FreeLing, you can build this sample program (or any
other you may want to write) with the command:
g++ -o sample sample.cc -lmorfo -ldb cxx -lpcre -lomlet -fries
Check the README file in the directory to learn more about compiling and using the sample
programs.
Option -lmorfo links with libmorfo library, which is the final result of the FreeLing compilation
process. The oher options refer to other libraries required by FreeLing.
You may have to add some -I and/or -L options to the compilation command depending on
where the headers and code of required libraries are located. For instance, if you installed some
of the libraries in /usr/local/mylib instead of the default place /usr/local, you’ll have to add
the options -I/usr/local/mylib/include -L/usr/local/mylib/lib to the command above.
