make: *** [tcldoc] Error 1

I was able to figure this out eventually, but it wasn't entirely clear to me... This should either be automatically set in the makefile when configuring, or at least documented with a comment in the makefile or something...

cal removed the tcldoc target entirely in r117902, so I guess that this can be considered to be "fixed" now...

Replying to mf2k@…:

Thanks for closing for me. While you are at it, #39778 can be closed similarly, as it is also about tcldoc in base.
