Re: [R] Source installation error: gfortran and gcc disagree on int and double ...
First, you replied to the list and not to me, which was discourteous. Your error does indeed appear to be an incorrectly installed compiler. conftestf.o: In function `cftest_': /home/mike/Desktop/R-2.3.1/conftestf.f:9: undefined reference to `_gfortran_pow_r8_i4' this is in -lgfortran, so that is not being found or is broken. One possibility is a missing symlink that is in a -devel RPM. This is not an R issue.

First, you do not need -fPIC: it is the same as -fpic which R selects on your platform.

Dear list, This problem has been posted before (http://finzi.psych.upenn.edu/R/Rhelp02a/archive/7982.html), That was over three years ago, for R 1.6.0 on Solaris, so I am not sure why you thought it would help. but suggestions did not help. My machine: AMD Duron 800 MHz, MandrivaLinux 10.2, gcc (and gfortran): 4.0.1, R source: 2.3.1. I had to set CPICFLAGS and FPICFLAGS to -fPIC. I tried ./configure with default CFLAGS and FFLAGS flags and with -O3 -g with the same error message. How can I pass the error?
