linux下R安装会遇到问题以及解决方法

How to install R on a local machine, the problems faced and troubleshooting

1. Download the tarball of R-2.6.2 from  http://www.icewalkers.com/Linux/Software/530020/R.html onto your local machine, for eg: ~/dist/R-2.6.2.tar.gzR-2.6.2 is the version currently in use by SSG

2. unpack it with

      ~src>tar xvfz ~/dist/R-2.6.2.tar.gz
   

3. cd to R-2.6.2
4. Read the INSTALL text file, the first instruction is to do

      ./configure
   

5. Will get an error for the above command

      configure: error: No F77 compiler found 
   

6. R requires Fortran compiler. Our desktop machines do have a Fortran compiler (gcc42-fortran). If your desktop machine does not have it, go to Yast and search for Fortran. Select gcc42-fortran and install
7. So we need to change the search variable in R-2.6.2/.configure file to accept the fortran compiler we have. Apply the patch below in order to do this

8. ~/src/R-2.6.2>patch --ignore-whitespace --backup ./configure << EOF
   6180c6180
   <            F95_compilers="f95 fort xlf95 ifort ifc efc pgf95 lf95 gfortran ftn g95"
   ---
   >            F95_compilers="f95 fort xlf95 ifort ifc efc pgf95 lf95 gfortran gcc42-fortran ftn g95"
   6192c6192
   <         3.*) GCC_Fortran_compiler=g77 ;;
   ---
   >         3.*) GCC_Fortran_compiler=gcc42-fortran ;;
   EOF
   

9. configure with readline=no like this

      ~/src/R-2.6.2> ./configure --with-readline=no 
   

10. Issue the following command make
11. link the bin/R so that R can be invoked from anywhere

        ~/src/R-2.6.2> ln bin/R R
