Thanks for the suggestion, but touching the unit test cpp doesn't cause
the test to rebuild when I just build the "final" target. Even running
bjam -a doesn't cause it to the link the unit test. I also even tried
putting the implicit-dependency onto the final target, which is
problematic because the library client shouldn't know what unit tests to
run, but unfortunately that doesn't trigger a link either.
Exact code below. I'm running Boost Build V2 (Milestone 12) and
Thanks for your help,
# To create needed cpp files for test, run:
# touch first.cpp final.cpp first_test.cpp
project dependency ;
using gcc : g++ ;
# test library definition
lib first : first.cpp ;
alias second : : : : <include>justforunittest ;
exe first_test : second first first_test.cpp ;
alias tested_first : first : : : <implicit-dependency>first_test ;
# client code that only wants to use tested library
exe final : tested_first final.cpp ;
$ touch first_test.cpp
$ bjam final
$ bjam -a final
