Use libgfrotran.so.3 and GFORTRAN_1.0 on fedora 27

Question

I am trying to use fortran code called SAMMY-8 which has its binary ready for use.

I was using without any issue while I had f25 installed. When upgrading to f27 I got the following error when trying to run the software

sammy: error while loading shared libraries: libgfortran.so.3: cannot open shared object file: No such file or directory

At first I though of making a soft link to libgfortran.so.4 by using

ln -s /usr/lib/libgfortran.so.4 /usr/lib/libgfortran.so.3

but when trying to run the code I got

sammy: /lib64/libgfortran.so.3: version `GFORTRAN_1.0' not found (required by sammy) 
sammy: /lib64/libgfortran.so.3: version `GFORTRAN_1.4' not found (required by sammy)

I also tried to install gcc-4.9.2 by installing the following rpm files

• devtoolset-3-gcc-4.9.2-6.2.el7.x86_64.rpm
• devtoolset-3-gcc-c++-4.9.2-6.2.el7.x86_64.rpm
• devtoolset-3-libstdc++-devel-4.9.2-6.2.el7.x86_64.rpm
• devtoolset-3-runtime-3.1-12.el7.x86_64.rpm

The installation was successful so I typed scl enable devtoolset-3 bash in order to be able to use gcc-4.9.2 and then run SAMMY again, but I still get

sammy: /lib64/libgfortran.so.3: version `GFORTRAN_1.0' not found (required by sammy)
sammy: /lib64/libgfortran.so.3: version `GFORTRAN_1.4' not found (required by sammy)

Any idea on how to GFORTRAN_1.0 and GFORTRAN_1.4 on f27?

Answer 1

libgfortran.so.3 from Fedora 9 : provides.log →

libgfortran.so.3(GFORTRAN_1.0)(64bit)    
libgfortran = 4.3.0-8

The original package libgfortran-4.3.0-8.x86_64.rpm will conflict, if any fortran dependent applications are installed (e.g. 'openblas-thread'), so a rebuild to a new name is required.

compat-libgfortran-4.3.0-8.fc27.x86_64.rpm installs with no issues. Link → https://drive.google.com/file/d/18uMtX2n4-bwM2V2TfOl-w_Fk8t6YSlsk/view?usp=sharing

Install: # cd Downloads/ && yum install ./compat-libgfortran-4.3.0-8.fc27.x86_64.rpm

P.S.: The objects GFORTRAN_1.0), GFORTRAN_1.4) are also present in later versions, till v.6.x : Fedora 24 → v. 6.3.1 ,

"compat" package = compat-libgfortran-6.3.1-1.fc27.x86_64.rpm : Updates the previous installed compat-libgfortran. Link https://drive.google.com/file/d/1f9nPFjuMBGg1XIza_Ajokkm_d7VYmF0_/view?usp=sharing

describe how you built the renamed packages

Write a new spec file ( I used pkgtool2 to create compat-libgfortran.spec https://drive.google.com/file/d/0B7S255p3kFXNQ0ZEbHB1V1BUa0E/view?usp=sharing )
