Problems installing R3.1.1 on Linux CentOS release 6.5 ( check LDFLAGS for paths to Fortran libraries )

Question

I'm trying to install R3.1.1 from sources on CentOS 6.5.

The .configure raises the following error

gfortran was installed using yum

 gfortran --version

I've no idea what I should put in LDFLAGS to fix that error.

Try to locate libgfortran.so in your system and provide the path -Lthe_path -lgfortran or set the respective environment variables. If that does not help, try to find more details in the config.log (or similar) file to find out what does the configure actually try to do in that check.

Your gfortran reports it is version 4.8.2 but the libraries are from version 4.4.4. Try to locate (by which) which gfortran binary you run and where are its libraries. Try running the locate command for libgfortran.
