https://bugs.kde.org/show_bug.cgi?id=435493 --- Comment #4 from Paul Floyd --- I recently setup a 10.13 VM so I might be able to look at this. And it looks like I previously befuddled Darwin and macOS versions. R is saying x86_64-apple-darwin17.0 (64-bit) which would be macOS. That's macOS 10.13 High Sierra. It doesn't seem to have been implemented here https://github.com/LouisBrunner/valgrind-macos/blob/master/coregrind/m_syswrap/syswrap-darwin.c -- You are receiving this mail because: You are watching all bug changes.

Ah I see, Big Sur. So this isn't built from the 'official' Valgrind source. You need to contact the maintainer of the homebrew fork. As Tom said, adding support for the missing syscall shouldn't be too hard. -- You are receiving this mail because: You are watching all bug changes.

I guess that when this syscall fails, R then reports the fatal error that it cannot create R_Tempdir. I do not have access to a macos system so cannot fix this but you might maybe try : it might be an easy 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, and then do a PRE(sys_mkdirat) in syswrap-darwin.c somewhat similar to the PRE(sys_mkdirat) in syswrap-linux.c (I guess only the syscall convention will have to be updated) -- You are receiving this mail because: You are watching all bug changes.
