Thanks a lot, Luis, for this workaround!

However, I still have trouble getting it work. My steps are the following:

1) Create a shell (wrapper) script that invokes pdfroff (respectively any other needed executable):

#!/bin/sh


/cygdrive/c/cygwin64/bin/pdfroff $*

Then compile this script into a Windows executable with shc:

shc -f pdfroff.sh

...rename the resulting executable pdfroff.sh.x to pdfroff.exe and move it into a directory inside c:\ProgramFiles . (I also tried /usr/local/bin and the current working directory.)

 

However, this is still doesn't work with pandoc; I still get the error message "pdfroff not found. Please select a different --pdf-engine or install pdfroff"
