Hi,
You'll need something like :
PKG_LIBS=-lgsl -lgslcblas
in your Makevars.
This is from package gsl (on CRAN). Or maybe you can just depend on the
gsl package and let it worry about finding where gsl is, etc ...

I have been working on an R package that calls C code using .C(). I recently

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
