I'm not sure why it doesn't occur on my recent Fedora machine with elfutils-0.182, but seems that -lpthread should be put after -ldw, so the change looks good to me. Would you post a formal patch? or I can fix it with your tag like Signed-off-by or Reported-by. > Also, I tried the master and version 1.6.7 on Linux kernel 5.10 and > got a kernel not supported error. Do we know when 5.10 will be > supported? Thanks. The latest is makedumpfile-1.6.8, but it was tested with up to kernel 5.9. I've tested the current master with kernel 5.10 to 5.11-rc5 on x86_64, it's ok so far. The next version will support 5.10 officially and will be released this spring or summer, but not scheduled yet.
