Here you go:
# fgrep -r tcp_info /usr/include/*
/usr/include/linux/tcp.h:struct tcp_info {
/usr/include/netinet/tcp.h:struct tcp_info
It seems to be exactly the same that on my ubuntu 14.04.
alpine linux natively use musl, an alternative libc library. I tried to
install a "real" libc instead, with the same error as above (that said, I
wonder how much my libc library was used or not, I'm investigating in that
direction).
Note that I don't have any problem compiling HAProxy 1.6-latest on the same
OS.
