[RTnet-developers] [BUG] rttcp.ko: __divdi3 undefined

[Sebastian S. <sm...@rt...>]

Hello Jan,

when trying to compile RT-TCP we get the following warning:

  CC [M]  /home/smolorz/tmp/tmp/rtnet/stack/ipv4/tcp/tcp.o
  CC [M]  /home/smolorz/tmp/tmp/rtnet/stack/ipv4/tcp/timerwheel.o
  LD [M]  /home/smolorz/tmp/tmp/rtnet/stack/ipv4/tcp/rttcp.o
  Building modules, stage 2.
  MODPOST 1 modules
WARNING: "__divdi3" [/home/smolorz/tmp/tmp/rtnet/stack/ipv4/tcp/rttcp.ko] 
undefined!

The reason is line 160 in timerwheel.c (division of a 64 bit variable).

We compile for x86_32.

Trivial fix committed.
