[Bioc-devel] Unable to use lldb debugger

[Martin Morgan]

When I try to debug on my macOS, I need to do the following

```
R -d lldb
(lldb) process launch --environment DYLD_LIBRARY_PATH=/Users/ma38727/bin/R-devel/lib
```
where `/Users/ma38727/bin/` is the location on my system where R is installed.

    Thank you Shian & Dolors for your replies.

    Shian, the error is on the C level so it does require a C level debugger
    (lldb being most useful). It does not require an M1 Mac though, so maybe I
    could try with my older mac next time... unless what Dolors says is true
    and I can no longer do the lldb command since my package requires R 4.0 or
    later.

    Thank you Dolors for finding that, that's the most information I've gotten
    about this. I can try that out the next time I have a similar issue, though
    hopefully by then Bioconductor or someone else can have updated
    instructions for debugging on a Mac.

    Kind regards,
    Hani
