[Rd] problem adding gdb to RTOOLS40 on Windows

[Voeten, C.C.]

Hi Mark,

Try pacman -Suy first to update pacman's package database. It's quite possible that the versions pacman is trying to install are no longer available due to being out of date.

HTH,
Cesko

Subject: [Rd] problem adding gdb to RTOOLS40 on Windows

I've not been able to install gdb for RTOOLS40 on Windows 10. The rtools installer (rtools40-x64_86.exe) doesn't seem to include gdb by default, and when I follow the instructions for adding gdb (which I tracked down at https://github.com/r-windows/docs/blob/master/faq.md) this is what happened:

<cd to c:\rtools\rtools40>
<run mingw64.exe>
$ pacman -S mingw-w64-x86_64-gdb

Something very similar happens if I try the 32bit version.

Do you have any suggestions?

 - I used to have this stuff working OK with R3.6/RTOOLS35 but have not needed to go back to C for a while. The version of gdb in RTOOLS is 7.9.1; I tried copying that gdb.exe into RTOOLS40 but it just exited instantly when I tried to run it from there. 
 
 - NB I have absolutely no idea what is meant by msys2 or pacman or any of that, I'm just following instructions... 


Thanks
Mark
