Installation of easifemBase on Linux

Ubuntu

System requirements

Then download the requirements by copying following code and paste it in terminal.

sudo apt-get update && sudo apt-get install -y gfortran gcc libomp-dev curl git \
python3 python3-pip cmake ninja-build \
liblapack-dev libopenblas-dev libhdf5-dev \
libplplot-dev plplot-driver-cairo libboost-all-dev \
gnuplot doxygen libgtk-4-dev

Install easifem CLI

The easiest way and the recommended way to install the components of easifem is through easifem command line interface.

python3 -m pip install --upgrade easifem

Set environment variables

After downloading the easifem CLI, we need to set three environment variables related to the location of the source files, build files, and installation of the easifem.

You can read about the environment variables here

easifem setenv --install ~/.easifem/install --build ~/.easifem/build --source ~/.easifem/src

Install External packages

easifem install extpkgs

You can also install individual package by using following:

easifem install openblas superlu lis metis scotch arpack fftw gtk-fortran lapack95 sparsekit gmsh

• The packages will be stored at EASIFEM_SOURCE_DIR/extpkgs/<pkg-name>
• The packages will be build at EASIFEM_BUILD_DIR/extpkgs/<pkg-name>
• The packages will be installed at EASIFEM_INSTALL_DIR/extpkgs/<pkg-name>

Install easifemBase

easifem install base

Installation by using CMake

Download the source code:

git clone https://github.com/vickysharma0812/easifem-base.git

or

git clone git@github.com:vickysharma0812/easifem-base.git

or

gh repo clone vickysharma0812/easifem-base

After downloading the source code, enter the source directory, and make a build directory.

cd easifem-base
mkdir ./build

EASIFEM uses CMake build system. You can install the Base library from CMake by using following steps

1. Configuration
2. Build
3. Install

To configure the Base library you can define following variables:

Variable	Type	Options
USE_OpenMP	BOOL	ON, OFF
CMAKE_BUILD_TYPE	STRING	Release, Debug
BUILD_SHARED_LIBS	BOOL	ON, OFF
USE_PLPLOT	BOOL	ON, OFF
CMAKE_INSTALL_PREFIX	PATH
USE_BLAS95	BOOL	ON, OFF
USE_LAPACK95	BOOL	ON, OFF
USE_FFTW	BOOL	ON, OFF
USE_GTK	BOOL	ON, OFF
USE_ARPACK	BOOL	ON, OFF
USE_SUPERLU	BOOL	ON, OFF
USE_LIS	BOOL	ON, OFF
USE_PARPACK	BOOL	ON, OFF
USE_METIS	BOOL	ON, OFF
USE_Int32	BOOL	ON, OFF
USE_Real64	BOOL	ON, OFF

An example of configuration step is given below:

export EASIFEM_BASE=${HOME}/.local/easifem/base
cmake -G "Ninja" -S ./ -B ./build \
-D USE_OpenMP:BOOL=ON \
-D CMAKE_BUILD_TYPE:STRING=Release \
-D BUILD_SHARED_LIBS:BOOL=ON \
-D USE_PLPLOT:BOOL=ON \
-D CMAKE_INSTALL_PREFIX:PATH=${EASIFEM_BASE} \
-D USE_BLAS95:BOOL=ON \
-D USE_LAPACK95:BOOL=ON \
-D USE_FFTW:BOOL=ON \
-D USE_GTK:BOOL=ON \
-D USE_ARPACK:BOOL=ON \
-D USE_PARPACK:BOOL=ON \
-D USE_METIS:BOOL=ON \
-D USE_Int32:BOOL=ON \
-D USE_Real64:BOOL=ON

After configuration, you can build and install the library by using:

cmake --build ./build --target --install
