I use ubuntu inside windows 10. I have a gfortran 4.8.5 and installed gfortran 9 by sudo apt-get install gfortran-9 followed https://fortran-lang.org/learn/os_setup/install_gfortran
When I type gfortran -v, it still leads to 4.8.5. Nevertheless, gfotran-9 -v leads to gcc version 9.3.0 (Ubuntu 9.3.0-11ubuntu0~14.04)
The problem is, when I use gfortran-9 compile a code, it leads to /usr/bin/ld: warning: libgfortran.so.3, needed by /usr/lib/gcc/x86_64-linux-gnu/8/../../../../lib/libblas.so, may conflict with libgfortran.so.5The code can still run, but I would like to avoid any possible conflict.
I searched a few times, still unsure what kind of configuration I need to circumvent the above message. Thank you very much.
