Hi,

I think I had similar problems with gsl on a non-standard installation. The following steps seemed to work (but are merely the results of struggling around...)

1. Download and extract source code of R-package 'gsl'
2. Use gsl-config --libs to get the path to GSL's lib directory (-L<path-to-lib>), use gsl-config --cflags to get the path to GSL's include directory (-I<path-to-include>)
3. Change Makevars in gsl/src:
- Add -L<path-to-lib> to PKG_LIBS
- Add (new) line: PKG_CPPFLAGS=-I<path-to-include>
4. Install gsl via
LDFLAGS=-L<path-to-lib>;export LDFLAGS;CPPFLAGS=-I<path-to-include>;export CPPFLAGS;R CMD INSTALL gsl

Best,

 Martin

Hi all, I am new to R and am writing after having contacted Robin Hankin, who
maintains the R gsl wrapper.

I am trying to use an AFNI (neuroimaging analysis) program that depends
on the R gsl package.   When I try to use the script I wrote, I get an
error that led me to suspect the gsl package was a culprit.  When I do
library("gsl") within R, I get:

Error in dyn.load(file, DLLpath = DLLpath, ...) :
  unable to load shared library
'/home/matt/R/lib64/R/library/gsl/libs/gsl.so':

  /home/matt/R/lib64/R/library/gsl/libs/gsl.so: undefined symbol:
gsl_sf_expint_En_e

Error: package/namespace load failed for 'gsl'

It looks like it is due to where my Linux (not R) gsl package is
installed.  Robin thought the problem is that I had to install my Linux
gsl package in a nontypical location (it's in /usr) because /usr/local
is not available to us.

He mentioned that others have had this problem.  Has anyone been able to
surmount this problem?
Thanks,

Matt
