LAPACK95 is a Fortran95 interface to LAPACK. This repository provides a facility to build LAPACK95 by using CMake build system. This repository is build mainly for satisfying the dependencies to build EASIFEM library. I would recommend you to use scivision's Lapack95 library instead of this one, which is avaiable here.

• The build process produces library called liblapack95 and modules. The archive library can be shared or static.
• The library is build for single and double precision.
• Complex data type is not included.

Following options are defined:

• -DUSE_OPENMP=ON/OFF : to enable and disable openmp
• -DCMAKE_BUILD_TYPE=Release/Debug for release or debug type build
• BUILD_SHARED_LIBS=ON/OFF to build shared or static lib
• -DCMAKE_INSTALL_PREFIX, location of the installion directory

git clone https://github.com/vickysharma0812/LAPACK95.git
cd LAPACK95
cmake -DUSE_OPENMP=ON -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX=${EASIFEM_EXTPKGS} -S ./ -B ./build
cmake --build ./build --target install

git clone https://github.com/vickysharma0812/LAPACK95.git
cd LAPACK95
python3 install.py

! Double precision
use la_precision, only: wp => dp
use f95_lapack, only: la_gesv

real(wp) :: A(3,3), b(3)

call random_number(A)
b(:) = 3*A(:,1) + 2*A(:,2) - A(:,3)

! Solve Ax=b, overwrite b with solution
call la_gesv(A,b)

print *, b
end program
