1. Clear all existence of apertium*, lt-*, hfst from the machine. Use which to find them (usually in /usr/local/bin)

2. This will install all of the Apertium packages, but we will replace half of them later:

   apt install apertium-dev cg3 hfst  # Ubuntu

3. Go to lttoolbox-java

   sh autogen.sh
   make
   make  # Might require running second time if the first one fails

   You should be able to run:

   > lt-proc-j -v
   org.apertium.lttoolbox.LTProc version 3.4.2

4. Go to lttoolbox

   git checkout tags/v3.4.2 -b v3.4.2
   sh autogen.sh
   make

   You should be able to run:

   > lt-proc -v
   lt-proc version 3.4.2

   Check with ls -l /usr/local/bin/

5. Go to apertium-kir

   Edit configure.ac:

   - PKG_CHECK_MODULES(APERTIUM, apertium >= 3.6.1)
   + PKG_CHECK_MODULES(APERTIUM, apertium >= 3.5.0)
   
   - PKG_CHECK_MODULES(LTTOOLBOX, lttoolbox >= 3.5.1)
   + PKG_CHECK_MODULES(LTTOOLBOX, lttoolbox >= 3.4.2)
   
   - PKG_CHECK_MODULES(CG3, cg3 >= 1.3.0)
   
   PKG_CHECK_MODULES(HFST, hfst >= 3.15.0)

   sh autogen.sh
   make  # can take 10+ minutes

6. In IntelliJ IDEA, create a new project and add lttoolbox-java/dist/lttoolbox.jar as a dependency. Check the box to copy it to lib

7. Copy apertium-kir/kir.automorf.bin to kotlin_test/src/main/resources/

Note

Currectly ther are symbolic links to lttoolbox.jar and kir.automorf.bin everywhere in the project

CLI Usage:

echo "боюнча" | java -jar lttoolbox.jar lt-proc apertium-kir/kir.automorf.bin
