Thanks, I've committed the patch to git. Not sure how to test-build it against boost1.88 though -- I can't seem to get both libboost1.88-all-dev and libleatherman-dev installed at the same time.How are you doing this?
I just removed libleatherman-dev from slic3r's dependencies and uninstalled it. ;) That was good enough for a quick test. The situation is a bit unfortunate, but it seems libleatherman needs to be rebuilt against boost 1.88 first.
