Hullo, I’m working on a SLES 11 SP3 system, with the gfortran 4.7 compiler. I’d like to update gfortran to one of the latest releases (6 or 7). Could anyone tell me step by step what I should do for the installation, and all the related dependencies issues? Thank you very much. Alessandro ---

Checking my test servers I believe the latest version of GNU Fortran available for SLES11 SP3 is 4.7 (or 4.8 for later releases) through the corresponding Software Development Kit (SDK). However with SLES12 SUSE introduced the Modules and Extensions with one being the Toolchain Module precisely to provide later versions of compilers - see [https://www.suse.com/communities/blog/suse-linux-enterprise-server-12-toolchain-module-released/](https://www.suse.com/communities/blog/suse-linux-enterprise-server-12-toolchain-module-released/) .. This provides GNU Fortran 5.3.1 and 6.2.1 and I expect in due course will provide 7.x. Basically if you want a later and supported version of GNU Fortran you should upgrade your server to SLES12 SP2. ## HTH.

Hi Not possible to look at updating the whole system to a supported release? There is a build on OBS, totally unsupported etc at; [https://build.opensuse.org/package/binaries/devel:languages:go/gcc6?repository=SLE\_11\_SP3](https://build.opensuse.org/package/binaries/devel:languages:go/gcc6?repository=SLE_11_SP3) Repository here; [http://download.opensuse.org/repositories/devel:/languages:/go/SLE\_11\_SP3/](http://download.opensuse.org/repositories/devel:/languages:/go/SLE_11_SP3/) Backup your system before adding this repo and installing gcc6, fortran etc. ---

A.[/QUOTE] Hi If you add the repository via YaST (or zypper) then install gcc6-fortran it will pull in dependencies. For example via zypper; ```auto zypper ar -f -g -n "SLE-11-SP3-gcc6" http://download.opensuse.org/repositories/devel:/languages:/go/SLE_11_SP3/ repo-gcc6 zypper ref zypper -vvvv in gcc6-fortran ``` The -vvvv will add verbosity so you can see what it’s going to do, then can make a choice to accept, any potential errors etc… ---

The last step with zypper gave me an error, but I was finally able to install gfortran-6 using yast.
