1. YodaOS Build Environment

This article introduces how to build environment/download/build/upgrade.

1.1. Build Compiling Environment

Linux Compiling Enviroment

YodaOS supports Ubuntu 14.04/16.04 LTS

Install depended-upon packages

sudo apt-get install build-essential subversion libncurses5-dev zlib1g-dev gawk gcc-multilib flex git-core gettext libssl-dev unzip texinfo device-tree-compiler dosfstools libusb

1.2. Download Source Code

YodaOS Project use Gerrit system from Google to manage the source code, will be open with github later.

Login Method Search https://openai-corp.rokid.com , the Rokid Developer website. If you are not already registered to Rokid Developer, sign up for a free account and within seconds you will get the gerrit page.
Access Permission Gerrit service supports SSH download only, you must add public key to the account.（the account->Settings->ssh public keys->add key）The developer must have specific authorization before downloading.

Install repo

Create a new bin directory in your home directory.

$ mkdir ~/bin
$ PATH=~/bin:$PATH

Get repo tool（circumvention technology）

$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

get repo tool (harmonious society)

  $ curl https://scm-deps-library.rokid-inc.com/linux/buildroot_dl_aml/tools/repo > ~/bin/repo
  $ chmod a+x ~/bin/repo

Download source code

Take the stable branch 7.30.x for example

repo init (google)

  repo init -u ssh://username@openai-corp.rokid.com:29418/kamino_universal_cust/open-platform/manifest -m yodaos-v7.30.x-20190103.xml

repo init (rokid)

  repo init -u ssh://username@openai-corp.rokid.com:29418/kamino_universal_cust/open-platform/manifest -m yodaos-v7.30.x-20190103.xml -repo-url=ssh://username@openai-corp.rokid.com:29418/tools/repo  --no-repo-verify

repo sync

1.5. Configure System and Application

YodaOS Project is based on the openWRT，so you would like have a general outline to begin with.

Openwrt directory

Original

scripts contains some compiling scripts, such as bash/python/perl scripts and so on.
tools automake, autoconf, sed, cmake
config contains the system configs
configs contains the board defconfigs
docs contains the openWRT module guide.
toolchain contains cross compilation tool chains，such as binutils/uClibc/gcc/glibc and so on.
target contains many board firmware and kernel modules, to generate the kernel and firmware image.
package The OpenWrt distributions provide several thousand packages to extend the functionality of your device.
package/rokid/ some rokid packages for YodaOS Project
include Contains some *.mk files for compiling, are included in makefiles.
feeds feeds are retrieved and managed by scripts/feeds, a perl script. The feeds script reads the configured feeds, obtains the current or specified version of each of them, and “installs” them. The default package contains packages、management、luci、routing and telephony. If want install other package, you can modify feeds.conf.default and update it.
- Update the package: ./scripts/feeds update -a
- Install the downloaded package: ./scripts/feeds install -a
dl download source code of packages when compiling.
others
- Makefile: This file is executed by make command in the top-level directory.
- rules.mk define some generic variables and functions for makefile
- Config.in The file associated with the configure by making menuconfig.
- feeds.conf.default The file used to download some third-party software packages.
- LICENSE & README the software license and the basic description of the software

build directory

build_dir contains host, toolchain-XXX and toolchain-XXX.
- host compile the tools used by the host in this directory.
- toolchain-XXX compile the cross-compile toolchain in this directory.
- target-XXX compile the target platform and packages in this directory.
bin contain the binary files and all the ipk files.
staging_dir store the compiled packages and install the cross-compile toolchain in the build_dir directory.
tmp the temp directory
logs This folder, sometimes you can see it, sometimes you don't. It appears while wrong, so you can get and analyze the wrong information.

Custom configure

make menuconfig and modify configure
diffconfig.sh

./scripts/diffconfig.sh > configs/<board>_defconfig

Compile package

clean, compile, install package

make package/<name>/{clean,compile,install}

clean, compile, install toolchain

make toolchain/{clean,compile,install}

Compile uboot

compile

make package/uboot-leo/compile

install

make package/uboot-leo/install

Compile kernel

compile modules

make target/linux/compile

compile zImage、dts and install

make target/linux/install

Configure kernel

make kernel_menuconfig

Choose Debug/Release

source envsetup.sh

...
...
You are building on Linux
Lunch menu... pick a image style:
1. debug(root filesystem bin is not striped)（limited by the size of K18, the root filesystem bin is striped）
2. release(root filesystem bin is striped)

./build.sh add the -d option

./build.sh -p leo_k18_universal_node -n openwrt-leo-k18-universal -f leo-k18-universal  -j32 -r -d

Release mode

1. the debugger doesn't need to package into image file.   
2. change the RKlog's default level to info.

Debug mode

1. enable macro CONFIG_DEBUG.
2. copy and install test tools into the image according to the macro definition.
3. change the RKlog's default level to debug.
4. add gdb/strace/valgrind and so on.

add custom package

please refer to https://openwrt.org/docs/guide-developer/helloworld/chapter3

add system service

take alab-libs for example, the customer does not want to run it while booting.

modify configure by the macro definition.

menu "Configuration"

config TURENPROC_AUTO_RUN
   bool "auto run"
   default y
   help
       turenproc service auto run

endmenu

determine whether to start up by the macro TURENPROC_AUTO_RUN definition.

if [ "$(CONFIG_TURENPROC_AUTO_RUN)" != "y" ]; then \
$(SED) "s/^START/#START/g" $(1)/etc/init.d/turenproc; \
fi
