[adegenet-forum] problem installation adegenet Ubuntu

[Didier AURELLE]

Dear all,

I tried to install adegenet on R version 3.6.3 on Ubuntu 20.04.1 with 
RStudio

I used the command :

install_github("thibautjombart/adegenet")


I first got an error that libgfortran.so.4 was not found so I created a 
symbolic link toward libgfortran.so.5 which was present in 
/usr/lib/x86_64-linux-gnu


Then I got a new error :

usr/lib/x86_64-linux-gnu/libgfortran.so.5: version `GFORTRAN_7' not 
found (required by 
/home/aurelle/R/x86_64-pc-linux-gnu-library/3.6/vegan/libs/vegan.so)


If I type in a terminal

gfortran - - version


I get

GNU Fortran (Ubuntu 9.3.0-10ubuntu2) 9.3.0


So I don’t know what to do. Do you have any idea ?


Thanks

Didier
