Daos source code

Download daos source code using the following command:

Code Block
languagebash
titlegit clone
linenumberstrue
 git clone --recurse-submodules -b v1.2-rc1 https://github.com/daos-stack/daos.git


Building DAOS & Dependencies

Once the sources are downloaded, the pre-requisites to build the source code can be installed by:

Note:

CentOS

Code Block
languagebash
titleBuild in Centos
linenumberstrue
cd daos
scons-3 --config=force --build-deps=yes install -j 8


SuSE

Code Block
languagebash
titleBuild in SuSE
linenumberstrue
cd daos
scons --config=force --build-deps=yes install -j 8


Environment setup

Once DAOS has been built, the environment must be modified to search for binaries and header files in the installation path. 


Code Block
languagebash
titleenv setup
# Within daos repository, after build step
source utils/sl/setup_local.sh
