| Subject: [PATCH 17/17] fix static detection of lock-free atomic ints |
| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |
| Content-Transfer-Encoding: 8bit |
| |
| When build statically, boost is unable to detect lock-free atomics ints |
| because it tries to link dynamically with boost_system, see |
| output/build/boost-1.67.0/bin.v2/config.log (with -d5 option): |
