--- Comment #3 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > I downloaded the source tar file from the gnu gcc repository. > As I stated 4.3.0 is not on the system, the latest version of gcc is 3.4.6. Am I correct to understand that you built gcc5.2 yourself using gcc3.4.6 as the bootstrap compiler? > I don't have any fortran code, the failure was during the build of > the R-3.2.2 package Could you post the outputs of which gfortran and gfortran -v Do you still have the directory in which R is built? If yes, you should find fortran codes inside it.
