R devel - Jan 2026 - Error when building R (89301+) on Windows 11 - but not every platform

I am compiling R on two different Windows 11 platforms. On one, my
home desktop, the process completes (89301) and passes check-all. On
my work laptop, however, the process consistently (89301, 89303,
89309) errors out during the making of the manuals right after
building refman.pdf. Please see below for the actual error. On both
platforms I use Rtools45, always up to date, and MikTex, always up to
date. The only functional difference I can think of is that my laptop
has severe security restrictions. I actually have some folders
whitelisted by my IT department solely to allow me to build R from
source. However, I have no idea which restrictions?if any?are
interfering. The fullrefman.log file seems to end without an issue
(see below). Line 127 in /trunk/doc/manual/Makefile.win is
opt="$(R_RD4PDF)"; \. Why that would be an issue on the laptop and not
my desktop is beyond me, especially as I am not even sure what that is
doing.

I ran this by Tomas on r-sig-windows first, thinking it may be a
windows issue, but he believes it is not.

Any thoughts, suggestions, or corrections would be appreciated.

Thank you,

Avi

You should scan the complete log for error messages. That a PDF was 
produced does not imply there were no errors (pdflatex is run with 
-interaction=nonstopmode), but a non-zero exit code usually means there 
were.

This is probably unrelated. Maybe the reported line number does not 
match the "physical" lines in the Makefile because some recipe lines
are
split. I believe the error happens in the first pdflatex run. You could 
call make with --trace to see more (force printing the recipe lines 
during execution), but you should really check the LaTeX log. I guess 
there is a problem with one of your LaTeX installations.
