could you show me what's the version of sys-fs/btrfs-progs? I see in your log: checking for btrfs_read_and_process_send_stream in -lbtrfs... no while here mine is: checking for btrfs_read_and_process_send_stream in -lbtrfs... yes obviously, we could also improve the code base.. to better btrfs case ..

Created attachment 454026 [details, diff] patch apply to btrfs-progs-4.8.3 fix this problem btw, I haven't enumerated source file one by one to check which funtions are missing, but blindly include ${objects} ( which is all source code!), and problem sloved here.
I sent a plea for help to the btrfs list. https://marc.info/?l=linux-btrfs&m=147984059821331&w=2
I think this regression was introduced here: https://git.kernel.org/cgit/linux/kernel/git/kdave/btrfs-progs.git/commit/?id=1c85c3de5aab997ff66ea95cb0f2c9f79726ec40
http://repo.or.cz/btrfs-progs-unstable/devel.git/commit/ffe3b1ba8673d566244c3cf520a659d3f0892449
Should be fixed in btrfs-progs-4.8.4.
