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

Essentially, the steps are: build with DEBUG=T (to have debug symbols), possibly updating EOPTS in MkRules.local to disable optimizations, then run gdb loading RGui, "set solib-search-path", run RGui from gdb. Then you can break to debugger from RGui menu, or just run the code that segfaults, and you get to gdb and can print the stacktrace, etc. You can find some information in...

Hi, I am trying to make a debug version of R ( for use with gdb later ) on windows. I am executing the following. src\gnuwin32>make clean src\gnuwin32>make DEBUG=T? In the output, I see many -O3 flags I do not see any ?-g -O0 flags? which ( I believe/I think ) that is what I need to debug R in gdb. What is the proper way to 'make' a 'Debug version of R'? Thank you,

...pile R on Windows 10 64-bit using LTO as I always do, I encountered a segmentation fault early in the compilation. I am uncertain as to what it means (please see below for error extract). I am using the most recent version of Rtools43 (5863) and updated its libraries prior to starting the build. My EOPTS is " -march=native -pipe -mno-rtm" and my LTO/LTO_OPT/LTO_FC/LTO_FC_OPT is "-flto=1 -fuse-linker-plugin". Any explanation or suggestions would be appreciated.

Hi All, I am trying to compile R from source on a 64 bit Windows. I have downloaded and installed all the third party software as per the R - documentation. The compilation starts fine and after a while it stops with the following error message: D:/Rtools/mingw_64/bin/../lib/gcc/x86_64-w64-mingw32/4.9.3/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lRgraphapp collect2.exe: error: ld
