Building SDL2 VICE from current code base from Sourceforge

svn checkout https://svn.code.sf.net/p/vice-emu/code/trunk vice-emu-code
cd vice-emu-code/vice/ 
./autogen.sh
./configure --enable-sdlui2              ##add other configuration options here
make -j $(nproc --all)                   ## Will use all processors 
sudo make install

Note: The latest version doesn't include the "x64" executable. However, you can get the same execution with "x128 -go64"
