Re: [Rcpp-devel] how to pass -fPIC instead of -fpic when building rccp package
Hi Dirk, Yes I agree, I'm just having issues with the way the build process works, so let's make it a Rcpp problem ;) library(Rcpp) Rcpp.package.skeleton(testpackage) R CMD INSTALL --preclean --no-multiarch testpackage icpc -I/usr/include/R -DNDEBUG -I/usr/local/include -I/usr/lib64/R/library/Rcpp/include -fpic -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -c rcpp_hello_world.cpp -o rcpp_hello_world.o icpc -shared -L/usr/local/lib64 -o testpackage.so rcpp_hello_world.o -L/usr/lib64/R/library/Rcpp/lib -lRcpp -Wl,-rpath,/usr/lib64/R/library/Rcpp/lib -L/usr/lib64/R/lib -lR installing to /home/aludin/R/x86_64-redhat-linux-gnu-library/3.0/testpackage/libs Here I'm using the Intel compiler as specified in my ~/.R/Makevars file: CC=icc CXX=icpc CFLAGS=-g -O -mtune=native So basically I have no idea where all the extra flags come from, in particular -fexceptions -fstack-protector -fpic I want to get rid of the -fstack-protector -fpic flags Cheers, Anwar On Jul 12, 2013, at 12:44 AM, Dirk Eddelbuettel e...@debian.org wrote: On 11 July 2013 at 15:12, Anwar Ludin wrote: | Hello, | | When building a rcpp package is there a way of forcing -fPIC instead of -fpic during package compilation?
