Package: libtool Version: 2.4.6-14 Severity: important Tags: upstream Forwarded: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=44605
As originally discussed in upstream bug report 44684, any package bootstrapped using the upstream libtool.m4 will fail to recognise macOS BigSur and use the wrong linker flags, which could result in issues when the libraries are later dlopen (ex: libgcrypt when used by Guile 3.0.7 through guile-gcrypt[2]) A partial fix for this was committed as debian/patches/0070-libtool-bigsur.patch but it only corrected the default call, and will break if MACOSX_DEPLOYMENT_TARGET=12.0 is provided (which will happen with the release of Monterrey next week) The simplest solution would be to change the last condition to match all versions instead of only "10.*|11.*" [1] https://debbugs.gnu.org/cgi/bugreport.cgi?bug=44684 [2] https://dev.gnupg.org/T5610
