How to Build

  • For buildroot-2019.02.3, Ubuntu 14.04 32bit
    $ sudo apt-get update
    $ sudo apt-get install g++ git libncurses5-dev
    $ cd buildroot-2019.02.3
    (Please patch first, see uppon, see buildroot-2019.02.3_bpi-m2z_patch/)
    $ make help
    $ make list-defconfigs
    $ make bananapi_m2_plus_defconfig
    $ make menuconfig
    (Enable Toolchain->Enable C++ support)
    $ make
    (Get sdcard.img under output/images/)
    (Put hellocpp and helloworld to package/)
    (Modify package/Config.in)
    ...
    menu "Miscellaneous"
    ...
    source "package/helloworld/Config.in"
    source "package/hellocpp/Config.in"
    $ make menuconfig
    (Enable Package->Misc->helloworld, hellocpp)
    $ make
    (After modify hellocpp source)
    $ make hellocpp-dirclean && make
    (Get new sdcard.img under output/image/)
    (Flash sdcard.img to tf card using Win32DiskImager, over)
