| R CMD config --ldflags

| -Wl,--export-dynamic -fopenmp  -L/home/prana/prana_R/third-party/install/lib/R/lib -lR -lrt -ldl -lm

| R CMD config CXXFLAGS

| 
|  R CMD config --ldflags
| 
| -Wl,--export-dynamic -fopenmp  -L/usr/lib/R/lib -lR -lpcre -llzma -lbz2 -lz -lrt -ldl -lm
| 
| R CMD config CXXFLAGS
| 
| -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -g

| These are the steps that I followed to install from sources
| 
| ./configure  --enable-R-shlib --with-x=no --with-readline=no
| --prefix=/home/prana/software/install/
| make
| make install

If I understand this question correctly then it has nothing to do with Rcpp
but wants to know how R is configured as an Ubuntu (or Debian) binary versus
a from-source installation.

The R-SIG-Debian list is appropriate for those questions. 

But it is off-topic for the Rcpp list. Please ask on rcpp-devel.
