Hi,
it seams that I cannot build criu-dev (I can still build the master branch):
In file included from soccr/soccr.c:9:0:
soccr/soccr.h:14:8: error: redefinition of ‘struct tcp_repair_window’
struct tcp_repair_window {
^~~~~~~~~~~~~~~~~
In file included from soccr/soccr.c:5:0:
/usr/include/netinet/tcp.h:319:8: note: originally defined here
struct tcp_repair_window
^~~~~~~~~~~~~~~~~
Currently using: Linux criu-devel 4.15.0-20-generic
Any idea?
cheers,
rodrigo
