I've managed it when setting threadapi to win32, but I'm attempting to use posix threads now. One thing that is problematic is it expects a library named pthreadsGC2.a, while mingw-w64's runtime provides a dll named libwinpthread-1.dll, which has import libraries named libwinpthread.dll.a and libpthread.dll.a, and static libraries named libpthread.a and libwinpthread.a. Attached is emerge's build.log, which shows several of the above undefined reference errors." Bugs closed To Be Determined thread Boost 1.65.0 Problem duplicate
