  10 # Installation j1939 for AGL
  11
  12 #### Minimum kernel version : 4.19
  13
  14 ## Compilation of kernel j1939
  15
  16 ##### Clone linux-can-next repository on kernel.org
  17
  18 ```bash
  19 git clone https://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next.git/
  20 ```
  21
  22 ##### Checkout on j1939 branch
  23
  24 ```bash
  25 git checkout j1939
  26 ```
  27
  28 ##### Add the compilation of the j1939
  29
  30 ```bash
  31 make menuconfig
  32         - Networking Support
  33                 - Can bus subsystem support
  34                         - <M> SAE J1939
  35                         - [*]   debug SAE J1939
  36 ```
  37
  38 ##### Compile
  39
  40 ```bash
  41 make
  42 ```
  43
  44 ##### Install
  45
  46 ```bash
  47 make modules_install
  48 make install
  49 ```
  50
  51 ##### Update grub
  52
  53 ###### CentOS/RHEL/Oracle/Scientific and Fedora Linux
  54
  55 ```bash
  56 grub2-mkconfig -o /boot/grub2/grub.cfg
  57 grubby --set-default /boot/vmlinuz-...
  58 reboot
  59 ```
  60
  61 ###### Debian/Ubuntu Linux
  62
  63 ```bash
  64 update-grub
  65 reboot
  66 ```
  67
  68 ##### Check if the installation is correct
  69
  70 ```bash
  71 modprobe can-j1939
  72 ```
  73
  74 If no errors are generated you have successfully install a kernel with j1939 module.
  75
  76 You can have a problem with header file, to check that go in the file /usr/include/linux/can.h
  77
  78 ```bash
  79 vi /usr/include/linux/can.h
  80 ```
  81
  82 If in the struct sockaddr_can you don't see j1939, the header are not upgrade.
  83
  84 So you need to do this manually, go to you're linux-can-next repository and do the following command:
  85
  86 ```bash
  87 cp include/uapi/linux/can.h /usr/include/linux/can.h
  88 cp include/uapi/linux/can/j1939.h /usr/include/linux/can/
  89 ```
