Source: tmux Version: 3.2a-3 Tags: patch upstream User: debian-cr...@lists.debian.org Usertags: ftcbfs
tmux fails to cross build from source (but 3.1 built), because 3.2 introduced a couple of AC_RUN_IFELSE without a guess for cross compilation or a suitable cache variable. I think for the relevant tests, it is best to assume the functions to work when they are present (during cross compilation). Please consider applying the attached patch. Helmut
