Re: [Qemu-discuss] Error in compiling migration-checkpoint.o

[Dave Gosselin]

A quick search of ‘rtnl_tc_get_ops’ on the Google machine revealed that it’s part of libnl (netlink protocol ibrary suite).  Please check and ensure that you have libnl devel package installed on your system.

Hi,

I am new to QEMU and want to use its fault tolerance feature by "Michael Hines" described in this page

http://wiki.qemu.org/Features/MicroCheckpointing

I followed these steps 

git clone http://github.com/hinesmr/qemu.git

$ git checkout 'mc'

$ ./configure --enable-mc

and installed the required libraries, but when I run the 'make' command I get the following error:

  CC    migration-checkpoint.o

migration-checkpoint.c: In function ‘mc_enable_buffering’:

migration-checkpoint.c:482:5: error: implicit declaration of function ‘rtnl_tc_get_ops’ [-Werror=implicit-function-declaration]

     if (!(ops = rtnl_tc_get_ops(tc))) {

migration-checkpoint.c:482:15: error: assignment makes pointer from integer without a cast [-Werror]

     if (!(ops = rtnl_tc_get_ops(tc))) {

               ^

cc1: all warnings being treated as errors

make: *** [migration-checkpoint.o] Error 1

Is this due to compiler version? Please advise.

Thanks,
