Subject: test: get list of objects from main Makefile
X-Git-Tag: 3.4~7
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=637530779815cdf61a95e830abffbc116d91d1aa;p=thirdparty%2Fchrony.git

test: get list of objects from main Makefile

Instead of linking unit tests with *.o in the root directory, which may
include conflicting objects from a different configuration (e.g. hash),
add a print target to the main Makefile and use it in the unit test
Makefile to link only with objects that are relevant in the current
configuration.
