I have several related questions.
1. Is it possible to use a GUI: Rstudio/Eclipse/Visual-studio to debug
compiled code on Windows? Things that work on Eclipse for Windows do not
work on Eclipse for Windows.
2. R CMD INSTALL seems to override default attempts to provide
CFLAGS="-DDEBUG -g3 -O0"
3. Is it necessary to compile R with debug turned on? One of the FAQs
mentioned to compile R with make DEBUG=T.
4. Using Rtools 4.0 and Jeroen's scripts for building R works great (many
thanks). But does not seem to have an impact on optimization, other than
including -gwarf-2. It adds -DNDEBUG flag. Is that sufficient for
debugging compiled code in a package? Obviously, I just need to debug
package code, so does it matter?
I am happy to write-up a FAQ.
Thanks, SM
