Perhaps someone can assist me make gfortran-7 as the alternative to gfortran-5. I use aptitude on the command line for everything in ubuntu. ![]() I am now trying to figure out how to make gfortran-7 the default, currently -version shows gfortran-5. Perhaps because of gcc-7, gofrtran-7 has installed. ![]() I managed to install gfortran-7 with sudo apt-get install gfortran In the following example, we will install the latest three versions of GCC and G++. Hello again, my apologies to those who have spent time looking at my problem. At the time of writing this article, the default Ubuntu repositories include several GCC versions, from 7.x.x to 10.x.x. Installing gfortran from gcc source, which provides for specifying languages to be installed gives an error (sfp-exceptions.c) at the make stage.ĭoes anyone know how I can have gfortran-7 installed. Please consider using a longer keyword or more keywords. Your keyword was too generic, for optimizing reasons some results might have been suppressed. You have searched for packages that names contain gfortran in all suites, all sections, and all architectures. I have successfully installed gcc-7 with sudo sed -i 's/xenial/zesty/g' /etc//ubuntu-toolchain-r*.list Ubuntu Package - gfortran.
