Dear Maintainer, This package fails to build from source with Make 4.4.1, most likely because of changes in $(shell) environment handling: environment variables exported from Makefiles are now made available to commands invoked using $(shell), which can cause issues with recursive definitions in particular. See https://salsa.debian.org/debian/make/-/blob/master/debian/NEWS for a complete list of backward-incompatible changes since Make 4.3. Below you will find how the builds end, hopefully the most relevant part from the build log. A full build log is available here: https://people.debian.org/~sanvila/make-4.4/build-logs/ Make 4.4.1 is currently available in experimental and will hopefully soon be uploaded to unstable, at which time this bug will become release-critical. About the archive rebuild: The build was made on virtual machines from AWS, using sbuild and a reduced chroot with only build-essential packages. If you could not reproduce the bug please contact me privately, as I am willing to provide ssh access to a virtual machine where the bug is fully reproducible. If this is really a bug in one of the build-depends, please use reassign and affects, so that this is still visible in the BTS web page for this package. Please reach out to the Make maintainer, Stephen Kitt <skitt@debian.org> if you need help fixing this. -------------------------------------------------------------------------------- -- Installing:
