Compile error with USE_DIST_PS=1

[ffmpbgrnn]

Hi, I'm using the latest version of cxxnet with all other components in the latest version. When I disable PS with USE_DIST_PS=0, everything works fine. But when I use USE_DIST_PS=1, it can't compile with the following error:

I think it might be that nvcc doesn't support C++11 well. I am using Centos5.6 with g++ version 4.9.2 and cuda version 6.5. Thank you!

Hi, I solved this by compiling with g++4.8.2, can you guys add a compiler requirement in the guide? Furthermore, ps-lite use glog(ps-lite/src/base/resource_usage.h:L3) which is now conflict with dmlc/logging, and I don't know whether I should report this issue to ps-lite as the conflict is happened when combines components together. The current master branch didn't even pass compiling (with ps-lite). And in tools directory, im2rec can't compile neither. Thank you!

Same on Ubuntu 15.04, I had to use gcc and g++ 4.8.4 to avoid this error.

hi Linchao,

thanks for the comment. cuda version 6.5 has problem with gcc 4.9 when using c++11. but it should be fixed in cuda 7.0.

i fixed the logging.h problem in ps-lite, please have pull.

best mu

@mli https://github.com/mli The bug still exists.

Could you please modify DEPS_PATH as the same way of CORE_PTH in https://github.com/dmlc/ps-lite/blob/master/Makefile#L17 ?

Should be fixed currently. But it has some minor problems on glog as I mentioned in dmlc-core.
