First of all, I'm not really skilled with these kind of stuff, so I may write stupid question, please be kind ;-)

I have an R code that call a c++ code. Unfortunately, there is a problem with my code, probably memory not mapped, and i would like to use valgrind to try to understand where the error is.

I already use it a couple of years ago, but now it seems to not work. When I lunch the following command

R -d valgrind

I get this output

and R is then not loaded. I don't know how to solve it.
I know that the error "Fatal error: cannot create 'R_TempDir'" could mean that there is no more space on the hard drive, but this is not the case.

I'm on macbook pro, with High Sierra, and R 3.5.0

Valgrind produces an error message telling that the unix:475 syscall is not handled.

In such a case, it reports to the guest application that the syscall failed,
with errno ENOSYS.

Syscall 475 on darwin is the mkdirat syscall. I guess that when this syscall fails,
R then reports the fatal error that it cannot create R_Tempdir.

As indicated in the error message, you should file a bug report on valgrind bugzilla.

You could also try to fix this : it might be a trivial change in the valgrind file
m_syswrap/priv_syswrap-darwin.h, to make something similar to e.g. the line
readlinkat a few lines above.
