Error using R via command line

Question

I am working on the mirtCAT package in R. I need to debug inside a function in this package called mirtCAT() . Inside this function there are many functions that are written in C ++. I need to see which function takes value. This is why I need to debug the C ++ functions that I am trying to use with gdb. For this, I refer to this document:

http://r-pkgs.had.co.nz/src.html#src-debugging

When I use the R --debugger=gdb command R --debugger=gdb to run R at the command prompt

It starts R, but I think it does not start the gcc compiler.

This is a warning:

unknown parameter '--debugger = gdb'

I changed the environment path variables for the gcc compiler.

Any suggestions anyone has?

PS I also referred to this topic: Debugging (line by line) a DLL created by Rcpp under Windows

Where @Dirk suggests running R with the command R -d gdb

which also does not work, he says:

 unknown option '-d' ARGUEMENT 'gdb' is _ignored_ 

Answer 1

Try:

 gdb Rgui.exe (gdb) break WinMain
