I was trying to install some more packages and ran into a problem
I hadn't seen before.
system sparc, solaris2.9
Fortran compilers available to me:
f77: Sun WorkShop 6 update 2 FORTRAN 77 5.3 2001/05/15
f90: Sun WorkShop 6 update 2 Fortran 95 6.2 2001/05/15
f95: Sun WorkShop 6 update 2 Fortran 95 6.2 2001/05/15
In fact I didn't ask for this one specifically, I had
"dependencies=TRUE" in a call to install.packages().
Following the installation instructions for R, I had selected F95
as my Fortran compiler.
The f95 compiler complained about nearly every line of
From the error messages as displayed on the screen, I could see no
reason for complaint. However, looking at the file with a text
editor immediately revealed the problem. The files
bsplvd.f bvalue.f bvalus.f loessf.f
qsbart.f sgram.f sinerp.f sslvrg.f
all use CR-LF line termination. The files
linear.f lo.f splsm.f
all use LF line termination expected on UNIX.
It turns out that the g77 and f77 compilers don't mind CR at the
end of a line, but f90 and f95 hate them like poison.
Removing the CRs makes f90 and f95 happy again.
I know how to fix the immediate problem. What I don't know is how
to intervene in the installation process. What I need to do is
- get and unpack files (steps normally done by install.packages)
- make changes (remove CR, edit configuration, whatever)
- resume whatever install.packages normally does
