Attention: this is an archived repository!

As time goes by, the OpenFST 1.8.1 (or maybe even earlier versions) stopped cross-compiling. Already the configure script tells you so.

Hence, remembering the original cause of this little project, specifically being able to work with OpenFST and OpenGRM on Windows, I decided to steer everyone with the same cause to another project of mine, opengrm-vagrant, which enables the same, even in three different ways:

1. Use Vagrantfile to configure a working environment
2. Use Dockerfile to create a Docker container
3. Use the shell script install-opengrm.sh with WSL (Windows Subsystem for Linux) to have an almost native environment

As implied above, this project will not be developed anymore.

OpenFST + OpenGRM-NGram + Thrax compilation for Windows using MinGW

The script compile_openfst.sh compiles static Windows binaries of OpenFST, OpenGRM-NGram and Thrax using the included Dockerfile.

Software versions

You can see the versions of the compiled libraries in the Dockerfile. Just search therein for the string ENV OPENFST_VERSION.

Prerequisites

Ensure that your Docker host has at least 3 GB RAM! This is required when compiling OpenFST and/or Thrax.

Results

The script/Dockerfile combination compiles both 32-bit and 64-bit binaries. After compilation, all resulting files are compressed to a .zip-file and are exported into the working directory of the script. The 32-bit binaries land in the openfst+ngram+thrax-mingw32.zip, the 64-bit binaries in the openfst+ngram+thrax-mingw64.zip respectively.

The binaries are static and thus self-sufficient. They reside in the bin directory in the archive.

In the directory lib you will find only static libraries (.a and .la files) for further developments.

Other directories contain supplementary files.
