sudo yum groupinstall 'Development Tools'

Ubuntu

sudo apt install build-essential

Install cmake

openEuler

sudo yum install cmake

Ubuntu

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:george-edison55/cmake-3.x

安装dbus
sudo yum install dbus-devel
查找dbus.h位置
$ sudo locate dbus.h
如果提示错误，执行 $ sudo updatedb
/usr/local/include/dbus-1.0/dbus/dbus.h
/usr/include/dbus-1.0/dbus/dbus.h
dbus默认安装到了dbus-1.0位置，需要调整dbus头文件位置，调整方法如下：
$cd /usr/include
$ ln -sf dbus-1.0/dbus

出现错误dbus/dbus-arch-deps.h：No such file or directory
查找该文件
$ locate dbus-arch-deps.h
/usr/local/lib/dbus-1.0/include/dbus/dbus-arch-deps.h
/usr/lib/dbus-1.0/include/dbus/dbus-arch-deps.h
将/usr/lib/dbus-1.0/include/dbus/dbus-arch-deps.h文件复制到/usr/include/dbus目录下

Ubuntu

sudo apt-get update
sudo apt-get install libdbus-1-dev

How to build

1. cd como

2. source build/envsetup.sh

   You will get these commands:

   $ help
   - comotools:            Switch to build como tools.
   - como_linux_x64:       Switch to build como for linux x64.
   - como_android_aarch64: Switch to build como for android aarch64.
   - debug:                Switch to build debug version.
   - release:              Switch to build release version.
   - build:                Build source codes.
   - build install:        Build source codes and install the building results.
   - rebuild:              Rebuild source codes.
   - rebuild install:      Rebuild source codes and install the building results.
   - clobber:              Clean the building results and generated files of the current project.
   - clobber all:          Clean all of the building results and generated files.

3. choose build target:

   • comotools to build tools
   • como_linux_x64 to build como for linux x64
   • como_android_aarch64 to build como for android aarch64

4. build or build -jn for release build

Change build type

1. in any build target:
   • debug for debug build
   • release for release build

Rebuild

1. rebuild or rebuild -jn

Clobber

1. clobber

Copy building results

if the build target is android aarch64, you need copy building results to the device.

• drop or drop all to copy all modules
• drop core to copy core modules
• drop test to copy testcase modules

Other commands

• root to change to como root directory
• out to change to out directory
• bin to change to bin directory
