Although, now that I think of it, the shown CMakeLists.txt file didn't use imported targets, so perhaps the order of libraries is literal and putting log_setup before log may indeed solve things. -----Original Message----- From: Peter Dimov Sent: Tuesday, September 15, 2020 20:28 To: boost@lists.boost.org Subject: Re: [boost] Boost Log 1.65.1 Linking Issue Andrey Semashev wrote:
I'm not sure, but I think the above would generate incorrect order of libraries in the linker command line. You need to ensure that boost_log comes after boost_log_setup, and their dependencies come after still.
CMake automatically orders libraries so that the dependencies come after. Unfortunately, FindBoost has a bug and declares log as depending on log_setup, rather than vice versa. https://github.com/Kitware/CMake/blob/bdcde7762c71cd27fcba6dc1a3efe12fa7a09f... No matter how you order the libraries in target_link_libraries, the order between these two will never be correct. Not sure if this is the problem here though.
