But now that we are here I took a look, and you "almost" got it right. Your
mistake was in using src/Makevars.in and not using a configure script to
create src/Makevars. So it remained unused. You can tell: with your setting
my box did
g++ -Wl,-S -shared -L/usr/lib/R/lib -Wl,-Bsymbolic-functions -Wl,-z,relro \
-o Temporal.so MatrixOps.o RcppExports.o -L/usr/lib/R/lib -lR
ie no linking the desired form! Where once fixed we see
g++ -std=gnu++11 -Wl,-S -shared -L/usr/lib/R/lib -Wl,-Bsymbolic-functions \
-Wl,-z,relro -o Temporal.so MatrixOps.o RcppExports.o \
-fopenmp -llapack -lblas -lgfortran -lm -lquadmath -L/usr/lib/R/lib -lR
which has the link instruction.
I send you a pull request with the simple fix. If you just the merge button
you should be all set.
