Maybe you want to check out the R package gsl and take a look how it is
solved there using a configure script that looks up the gsl installation.
Best wishes,

I have been working on an R package that calls C code using .C(). I recently
started including some functions from the GNU Scientific Library in my code.
The code runs fine on my machine when not wrapped in the package. But I get the

Clearly there is some difficulty linking up with
gsl_multimin_fminimizer_nmsimplex.
I noticed the QRMlib library also includes gsl functions. In that package they
include a src/gsl directory with the required .h files and in Makevars they
have "PKG_CFLAGS = -I./gsl". I have copied this approach, but wonder if using
the standard
"R CMD build myPackage"
"R CMD check myPackage"
needs modifying in some way?
All hints or ideas welcome.
Thanks
David
