compiling_HFS T3

Run these commands:

On Mac:

curl http://apertium.projectjj.com/osx/install-nightly.sh > install-nightly.sh
chmod a+x install-nightly.sh
sudo ./install-nightly.sh

On Linux ubuntu:

wget https://apertium.projectjj.com/apt/install-nightly.sh -O - | sudo bash
sudo apt-get -f install apertium-all-dev

On Linux fedora (e.g. on gtlab):

curl https://apertium.projectjj.com/rpm/install-nightly.sh |sudo bash
sudo apt-get -f install apertium-all-devel

This downloads a shell script (1), makes it executable (2), and runs it (3). The shell script in turn will download and install prebuilt binaries for:

• hfst
• vislcg3
• apertium

You get the latest version of all required tools in one go, no compilation required! : ) Rerun with regular intervals to get the latest updates.

If you want to configure and compile the source code, do as follows:

Checkout and configuration

We assume installation from svn here. You can downloaded a tarball from the Hfst Github site. Then unzip and untar, and go directly to the ./configure step.

svn co https://github.com/hfst/hfst.git/trunk hfst
cd hfst/
./autogen.sh
./configure --enable-all-tools --with-unicode-handler=glib

The configuration above is the default used by the Giella infra. To check what other options there are, do ./configure --help.

To avoid the very wordy output of make, and get only essential messages, add the following ./configure option:

--enable-silent-rules

Make and install

The final steps to build and install hfst after the configuration are as follows:

make
sudo make install

installing the SWIG Python binding

NB!! The following info is most likely outdated. See the Hfst readme file for further details.

If you want to run hfst from Python, you need to install the Python binding provided through SWIG. First you need to install swig and the Swig submodule for Python using MacPorts:

sudo port install swig
sudo port install swig-python

When done, you are ready to build and install the Python bindings:

python3.3 setup.py build_ext --inplace

Special configuration on MacOSX 10.9

Due to a new default compiler on MacOSX 10.9 (with which the hfst code - presumably the openfst backend - is not compatible), one needs additional configuration flags. Try one of these:

./configure --without-foma --with-unicode-handler=glib --enable-all-tools \
            LDFLAGS=" -stdlib=libstdc++"

Or:

./configure --without-foma --with-unicode-handler=glib --enable-all-tools \
            CXXFLAGS=" -stdlib=libstdc++" LDFLAGS=" -stdlib=libstdc++"

Or:

./configure --without-foma --with-unicode-handler=glib --enable-all-tools \
            CXXFLAGS="-I/usr/include/c++/4.2.1" LDFLAGS=" -stdlib=libstdc++"

NB! Remember to make clean after each ./configure run, and before you make

NB2! This does NOT apply to MacOSX 10.10 - in this case, just configure without any extra flags, as described earlier. This might be because the hfst build instructions are improved, or because of changes in Apple's compilers. If it is because of changes in the Hfst code base, the above workaround is probably obsolete also on MacOSX 10.9, but this needs to be tested.

Extra preparations on MacOSX 10.6

When building from the github source code, OSX 10.6 and earlier requires newer versions of automake and autoconf than provided by the system, and hfst-ospell requires pkg-config to configure. Also the flex and bison versions installed breaks hfst compilation. Ensure you have MacPorts installed, then do the following before anything else:

sudo port install automake autoconf flex bison pkgconfig

After this, do ./autogen.sh etc. as above.
