<div>| Hi,</div>
<div>| </div>
<div>| Recently I am trying to use GSL for improving my code and I found RcppGSL is</div>
<div>| really great. BUT I am stuck by configuring it for a few days. What I've done</div>
<div>| is as:</div>
<div>| </div>
<div>| 1. Install Rcpp and RcppGSL;</div>
<div>| 2. Download "local320.zip" file and unzipped it as "LIB_GSL"</div>
<div> </div>
<div>You don't "unzip it as 'LIB_GSL'. You can ubzip it anywhere. Say you use </div>
<div>c:/libs/gsl/ -- but then you have to set the _environment variable_ named</div>
<div>LIB_GSL to the _value_ of the location you used, eg c:/lib/gsl</div>
<div> </div>
<div>| 3. Add an environment variable LIB_GSL, and make it as "D:/LIB_GSL"</div>
<div>| 4. Edit the "Makevars.win" as follows:</div>
<div>| </div>
<div>| PKG_CPPFLAGS=-I$(LIB_GSL)/include -I../inst/include</div>
<div>| PKG_LIBS=-L$(LIB_GSL)/lib/x64 -lgsl -lgslcblas $(shell "${R_HOME}/bin$</div>
<div>| {R_ARCH_BIN}/Rscript.exe" -e "Rcpp:::LdFlags()")</div>
<div> </div>
<div>What did you edit? Why did you think you needed to edit?</div>
<div>| </div>
<div>| Then I started to run the example code:</div>
<div>| </div>
<div>| > sourceCpp("bSpline.cpp")</div>
<div>| </div>
<div>| I got the following errors:</div>

<div>| </div>
<div>| I've no idea what happened. Did I miss anything or do something wrongly? Many</div>
<div>| thanks!</div>
<div> </div>
<div>It seems to have found the headers (or else it would not have compiled) but</div>
<div>not the library. Check D:/LIB_GSL/lib/ and see if it has the missing</div>
<div>libraries libgsl and libgslcblas.</div>
<div> </div>
<div>All this is used the same way at CRAN so it works there....</div>
