• lua5.1 - In a build step, generates the c++ bindings for lua
  

1. Open a terminal, create the directory raspberrypi and cd into it
   
2. Inside of the directory raspberrypi, create a directory named rootfs. Now the raspberry pi image is required.
   
3. For mounting the image the offset of the second partition is required. Run this with sudo or as root:
   

   fdisk -l <path to raspberry image>

   
   
4. Example of the output:
   

   Disk 2019-07-10-raspbian-buster-lite.img: 2 GiB, 2197815296 bytes, 4292608 sectors
   Units: sectors of 1 * 512 = 512 bytes
   Sector size (logical/physical): 512 bytes / 512 bytes
   I/O size (minimum/optimal): 512 bytes / 512 bytes
   Disklabel type: dos
   Disk identifier: 0x17869b7d
   
   Device                              Boot  Start    End Sectors  Size Id Type
   2019-07-10-raspbian-buster-lite.img1        8192  532480  524289  256M  c W95 FAT32 (LBA)
   2019-07-10-raspbian-buster-lite.img2      540672 4292607 3751936  1.8G 83 Linux

   
   
5. Multiply the second number under start by 512
   

   540672 * 512 = 276824064

6. This command has to be run with sudo or as a root user.
   

   mount -o offset=276824064 <path to img file> /mnt

   
   
7. Run this commands with sudo or as root, to copy the lib and usr (can take a while is over 1,5 GiB big) directory into the raspberrypi/rootfs directory:
   

   cp -r /mnt/lib $HOME/raspberrypi/rootfs
   cp -r /mnt/usr $HOME/raspberrypi/rootfs

   
   
8. Run this with sudo or as root, to unmount the raspberry pi image:
   

   umount /mnt

   
   
9. Create a file named pi.cmake in directory raspberrypi and add this content:
   

   SET(CMAKE_SYSTEM_NAME Linux)
   SET(CMAKE_SYSTEM_VERSION 1)
   SET(CMAKE_C_COMPILER arm-linux-gnueabihf-gcc)
   SET(CMAKE_CXX_COMPILER arm-linux-gnueabihf-cpp)
   SET(CMAKE_FIND_ROOT_PATH $ENV{HOME}/raspberrypi/rootfs)
   SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
   SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
   SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

   
   
10. The compiling environment has been setup. Now cd into the cuberite source or clone it if you haven't it
    
11. Inside of raspberrypi create the directory Release and cd into it:
    

    cmake -D CMAKE_TOOLCHAIN_FILE=$HOME/raspberrypi/pi.cmake -DCMAKE_BUILD_TYPE=RELEASE ..

12. For compiling you can add the number of cores / processors it should use. Run nproc to see how many threads are possible, e.g. 4
    
    

    make -j<number of cores to use>
    make - Only uses one thread
    "make -j4" - Uses up to 4 cores / processors, if available

13. If it was successful the executable is inside the directory <path to cuberite>/Server
