Dakota is a flexible tool which compounds a lot of mathematical and statistical methods. Dakota is extremely useful when we combine it with a simulation procedure such as OpenFoam.

However, Sandia Lab does not provide a build version for Ubuntu. Also, when I look around some forums, there is no detailed tutorial shows how to do that. Therefore, I write this one to share my way, step by step. I hope this could help someones those are not familar with compiling app in Ubuntu. The build was done for dakota 6.4 but might work with newer versions.

“Update 2017-11-20: This build works for dakota v6.7”

### 1 Preparation:

  ~$sudo apt-get install gcc g++ gfortran cmake cmake-curses-gui libboost-dev libboost-all-dev libblas-dev liblapack-dev libopenmpi-dev openmpi-bin openmpi-doc xorg-dev libmotif-dev  ​ Explain: • GNU 4.8 compilers: gcc g++ gfortran • CMake 2.8.12: cmake cmake-curses-gui • Boost: libboost-dev libboost-all-dev • Linear Algebra: libblas-dev liblapack-dev • OpenMPI: libopenmpi-dev openmpi-bin openmpi-doc • XWindows: xorg-dev libmotif-dev • Python (optional): Python development dependencies (if using direct Python interface: python-dev, and python-numpy if you’d like a NumPy interface. #### 1.2 Download DAKOTA source code on website. • At the moment I wrote this tut, I successful compiled the newest version of Dakota (v6.7). So you can download any version you want to use from v6.4 –> 6.7. • Create DAKOTA folder and download the source into it. #### 1.3 Extract file in terminal. • Open terminal in DAKOTA folder and run the following code $ tar -xzf dakota-<version>-public-src.tar.gz

• Now we have the source code.

#### 1.4 Create and go to dakota-6.4.0 folder

• From version 6.5, if you make the build and installation in the same folder, error may occur. So, I suggest we should make separated folders for each. In the case you want to install in /usr/local/bin, you can obmit the install folder.
  $mkdir dakota_build$ mkdir dakota_installation
$export DAK_BUILD=$HOME/DAKOTA/dakota_build
$export DAK_INSTALL=$HOME/DAKOTA/dakota_installation
$export DAK_SRC=$HOME/DAKOTA/dakota-<version>-public-src
$cd$DAK_BUILD


- Note: dakota-<version>-public-src is folder where you extract dakota files.

  $cp$DAK_SRC/cmake/BuildDakotaTemplate.cmake $DAK_SRC/cmake/BuildDakotaCustom.cmake  ### 2 Building #### 2.1 Run Cmake • If you want to install dakota in specific folder, you need to config -DCMAKE_INSTALL_PREFIX to folder you want: $ ccmake -C $DAK_SRC/cmake/BuildDakotaCustom.cmake$DAK_SRC -DCMAKE_INSTALL_PREFIX=$DAK_INSTALL  • If you want to install dakota in default folder. $ ccmake -C $DAK_SRC/cmake/BuildDakotaCustom.cmake$DAK_SRC


Note:

• Cmake shows a simply GUI and when you enter in ccmake, first press the key “c” to configure the script.
• If any error appears, go to the last line to check. If no, press “e” to return the main GUI.
• In main GUI, press “t” to toggle some features. Now you can move down and up the cursor. You can turn ON and OFF the features by press Enter.
• Go down, find BUILD_SHARE_LIBS and turn it OFF (by default: it's turned ON). We turn off this since it conflicts with a library in OPENFOAM (libsampling.io).
• You also can move down to check the HAVE_X_GRAPHICS feature ON or OFF. This function shows a graph when u run dakota.
• All finish, press “c” again to configure all scripts. If no error appears, you can press “e” to back to the main menu.
• Finally press “g” to start generating the configuration.

#### 2.2 Run make

(The -j option means we will compile in parallel. In this case I am compiling with 4 processors. You can adjust this option to suit with your hardware)

   $make -j4  #### 2.3 Install $ make install


### 3 Path and Test

#### 3.1 Add Path

• If you install dakota in your specific folder, do not forget to add the following environment variables to your .bashrc file. Add the following lines at the end of bashrc and save
   $gedit ~/.bashrc$ export PATH=$PATH:~/DAKOTA/dakota_installation/bin:~/DAKOTA/dakota_installation/test$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/DAKOTA/dakota_installation/bin:~/DAKOTA/dakota_installation/lib  • If you install in default folder, just obmit this step. #### 3.2 Test build $ dakota -v


If the screen show the version and build date, the job is finished! You also can follow the steps on the Dakota website to fully check the installation.

Congratulation! Now you can use dakota in Ubuntu.
