Build with gfortran on Mac

Environment Construction

First, install brew on a terminal.

% /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

At the end of the installation, “====> Next steps:” appears, indicating the work to be done after the installation. If it indicates that you need to add a description to the .zprofile, follow the instructions. After that, update the package as follows.

% brew update
% brew upgrade

Then, install gfortran and gnuplot.

% brew install gfortran
% brew install gnuplot

Build for AkaiKKR

After creating a working directory for AkaiKKR, use “cd” to move there.

% mkdir AkaiKKR
% cd AkaiKKR

Put the latest version of AkaiKKR you downloaded into the AkaiKKR directory you created. After extracting the file, use “cd” to move to the extracted directory.

% tar zxvf cpa2021v01.tgz
% cd cpa2021

Then, open the makefile with your favorite editor such as “vi”, “nano”, etc. Followings are lines 15 and 16.

fort = ifort
#fort = gfortran

Add “#” to the beginning of line 15 and delete “#” from the beginning of line 16.

#fort = ifort
fort = gfortran

This operation switches the compiler from ifort to gfortran. After editing, save and exit. Then, build.

% make
% make gpd
% make spc

If executables “specx”, “gpd”, and “spc” are present, the build has succeeded.

Operation Check

The operation can be checked by executing the following command in the directory where the build was performed.

$ ./specx < in/fe
