<br>
<br>Recently I am trying to use GSL for improving my code and I found RcppGSL is really great. BUT I am stuck by configuring it for a few days. What I've done is as:
<br>
<br>1. Install Rcpp and RcppGSL;
<br>2. Download "local320.zip" file and unzipped it as "LIB_GSL"
<br>3. Add an environment variable LIB_GSL, and make it as "D:/LIB_GSL"
<br>4. Edit the "Makevars.win" as follows:
<br>
<br>PKG_CPPFLAGS=-I$(LIB_GSL)/include -I../inst/include
<br>PKG_LIBS=-L$(LIB_GSL)/lib/x64 -lgsl -lgslcblas $(shell "${R_HOME}/bin${R_ARCH_BIN}/Rscript.exe" -e "Rcpp:::LdFlags()")
<br>
<br>Then I started to run the example code:
<br>
<br>> sourceCpp("bSpline.cpp")
<br>
<br>I got the following errors:
<br>
<br>g++ -m64 -I"D:/PROGRA~1/R/R-31~1.1/include" -DNDEBUG -ID:/LIB_GSL/include -ID:/LIB_GSL/include -I../inst/include -I"D:/PROGRA~1/R/R-31~1.1/library/Rcpp/include" -I"D:/PROGRA~1/R/R-31~1.1/library/RcppGSL/include" -I"E:/Dropbox/Paper/HIGHPE~1/packages/RcppGSL/inst/examples/bSpline" -I"d:/RCompile/CRANpkg/extralibs64/local/include" -O2 -Wall -mtune=core2 -c bSpline.cpp -o bSpline.o

<br>
<br>I've no idea what happened. Did I miss anything or do something wrongly? Many thanks!
