Building on Windows using Cygwin

Tested on Cygwin 2.10.0 under Windows 10, with link-grammar version RC 5.5.2.

Language bindings

The build system produces successful Python3 and Java bindings. Other language bindings have not been tested.

For the Java bindings, install Java and Ant under Windows. Make sure, under Windows, that JAVA_HOME is set correctly and ant is the PATH.

Building

Install all the prerequisite tools, Also install the desired optional libraries

Note: Installing the library pcre2 is required for correct operation since the default REGEX implementation (in libc) is not capable enough.

Use the configure command as outlined in the main README. Note that compiling with more than one concurrent process may be extremely slow. To make sure only a single process is used supply make with -j 1. Also, the make built-in rules cause a lot of I/O and are not needed here, so supplying make with the -r argument makes it much faster.

$ make -r -j 1

$ make -r install

The dictionaries are installed by default under /usr/local/share/link-grammar.

Running link-parser

  • From the sources directory, using cmd.exe Windows console:

Note: ^Z/^D/^C are not supported when running under Cygwin! In particular, don't press ^Z - it may crash or stuck the window. To exit, use the !exit command.

  > PATH-TO-LG-CONF-DIRECTORY\link-parser\link-parser [arguments]
  • Form the Cygwin shell:

Before installation (supposing no installed version yet):

  `$ PATH-TO-LG-CONF-DIRECTORY/link-parser/link-parser [args]`

After "make install" (supposing /usr/local/bin is in the PATH):

  `$ link-parser [arguments]`

To run the executable from other location, liblink-grammar-5.dll needs to be in a directory in PATH (e.g. in the directory of the executable).

A helper BAT file link-parser-cygwin.bat is provided (currently under the mingw directory) for invoking link-parser.

For more details, see "RUNNING the program" in the main README.

Tests

All the tests pass (the Python and C++ tests in the tests directory). However, the C++ tests that involve multi-threading severely trash the system and take very much time to complete.
