Hi,
if you use emacs you might do the following (tested in Linux, but
ideally possible in Windows too):
1) open R in emacs (M-x R) and load the *.so. At developement stage it
might be useful to use sourceCpp
2) open gdb (M-x gdb) in emacs
3) look for R session id (see "ps" command), let's assume it's 1234
4) In the gdb shell:
a) attach 1234
b) set breakpoints
c) signal 0
5) now run R commands and you'll get the debugger stop once into you code

Hi,
Pardon me. I am relatively new.
What is a way ( or effective way ) to debug an Rcpp/RCppArmadillo
program that is running within R?
Do I try somehow to set an inline RCpp/RCppArmidillo
script attribute to 'Debug' ( if this exists? )
Do I recompile R ( with perhaps 'g++ -g -O0' and try to debug an
Rcpp/RCpp Armadillo file (.so/.dll) in an attached process in the gdb
debugger?
Do I just create an ( independent from R ) Armadillo C++ program .exe
( made with 'g++ -g -O0 )
( and use my own BLAS/LAPACK ) outside of R, and just debug the .exe
it using gdb?
Or, do I simply, in R, just put many 'print statements' in the inline
RCpp/RCppArmidillo script?
What is a strategy?
Thank you,
