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 following error from "R CMD check"
* checking whether the package can be loaded ... ERROR Loading required package: splancs Loading required package: sp Spatial Point Pattern Analysis Code in S-Plus Version 2 - Spatial and Space-Time analysis Loading required package: ellipse Loading required package: mvtnorm Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared library '/home/david/papers/inProgress/sharka_istanbull/package/sharka.Rcheck/sharka/libs/sharka.so': /home/david/papers/inProgress/sharka_istanbull/package/sharka.Rcheck/sharka/libs/sharka.so: undefined symbol: gsl_multimin_fminimizer_nmsimplex Error in library(sharka) : .First.lib failed for 'sharka' Execution halted 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.
