GNU APL is easy to build on your own Linux machine, though the steps aren't detailed on the website.

Benefits of building yourself locally:

• One can customize how many cores GNU APL has access to
• Customizing optional extensions like PNG image, SQLite, GTK support etc.
• Having the latest bugfixes

1. Obtain the latest source

   • mkdir apl-build
   • svn checkout http://svn.savannah.gnu.org/svn/apl/trunk

2. Configure using autotools

   • cd trunk
   • make clean
   • ./configure CORE_COUNT_WANTED=3 RATIONAL_NUMBERS_WANTED=yes --with-ctrld_del

   Use ./configure --help to see other options, adjust to taste

3. Build and install

   • make -j && sudo make install

4. Set up your default workspace

   • cd ~
   • mkdir -p GNUAPL/workspaces
