Package: dpkg-dev Version: 1.19.2 Severity: normal The header comment in vendor.mk says:
# The snippet also defines a macro "dpkg_vendor_derives_from" that you can # use to verify if the current vendor derives from another vendor with a # simple test like this one: # ifeq ($(call dpkg_vendor_derives_from ubuntu),yes) # ... # endif But dpkg_vendor_derives_from is defined like this: dpkg_vendor_derives_from = dpkg-vendor --derives-from $(1) && echo yes || echo no So the documentation is wrong in two ways: * that's not how passing arguments to $(call) works * the result of the macro needs to be passed to $(shell) A working version of the test in the header comment would be: # ifeq ($(shell $(call dpkg_vendor_derives_from,ubuntu)),yes) This seems a bit cumbersome and I don't know whether it's actually the interface you intended, although presumably there would be compatibility concerns with changing it. (I noticed this because I tried to use dpkg_vendor_derives_from in openssh, and then Jeremy Bicha pointed out to me that it broke: https://salsa.debian.org/ssh-team/openssh/commit/2df9bff12640a33749f0f20ae806b6efac327116#note_52100) Thanks, -- Colin Watson [cjwat...@debian.org]
