rosmake errors when using g2o::RobustKernelDCS to createRobustKernel

[giepy]

Hi,

I tried to use g2o::RobustKernelDCS to replace g2o::RobustKernelCauchy to createRobustKernel. When I run "rosmake dvo_slam", there were several errors as follows:

make[3]: Entering directory `/home/islab511/Desktop/ljw_dvo/dvo_slam-fuerte/dvo_slam/build'

And I found that we cannot modify the code of 'g2o'. If I modify the code of 'g2o', in the next compiling the code return to the original. I have no idea with these problem. Please help me!

Thanks.

add the modified createRobustKernel() as follows:
g2o::RobustKernel* createRobustKernel()
{
if(cfg_.UseRobustKernel)
{
//2015-5-23: g2o::RobustKernel Cauchy
//g2o::RobustKernel* k = new g2o::RobustKernelCauchy();
//k->setDelta(5);
g2o::RobustKernel* k = new g2o::RobustKernelDCS();
k->setDelta(5);
return k;
}
else
{
return 0;
}
}
'namespace' had been added in the code. But the problem exists, too. What problem ? What can I do for it ? Is there someone to help me?
