I don't know where you have gdb from, but it is not included in the latest
xcode, afaik.
If you install it by hand, or from brew, then you'll see what I saw.
Maybe you have a gdb version from an older xcode lying around, or I don't
know. See also

Iâm not sure whatâs going on with your setup, but this is what I get on my
machine when I press Ctrl-C just after the R prompt comes up when started with
âR -d gdb":
Program received signal SIGINT, Interrupt.

What do you mean by this? Gdb is a debugger, and LLVM is a compiler
infrastructure. Perha

Small note: if you are using a recent version of OSX, then gdb is
essentially useless, but you can use llvm, which is nicer in many respects,
anyway.

Saisai,
I haven't watched the specific video Sandip posted, but from the title it
looks to be correct. Running R with/in gdb is the correct way to debug C
code in R packages.
One thing to watch out for: The default compiler flags for C/C++ code in R
packages call for substantial optimization (I b

Hi all,
Sorry to bother you.

modified a R package with C code.
I would like to modified the C code within the R package, and want to debug the
C program. But I have no idea how to debug this kind of R package.
