Failed to run make -j8

[lomograb]

After I ran command make -j8, I'm getting this error :
/usr/include/google/protobuf/arenastring.h:219:31: note: candidate expects 1 argument, 0 provided Makefile:575: recipe for target '.build_release/src/caffe/data_transformer.o' failed make: *** [.build_release/src/caffe/data_transformer.o] Error 1
I'm using Ubuntu 16.04. Protobuf 3.2
Downgrading Protobuf to 3.1 also didn't work

@lomograb Can you install Caffe successfully in your system?

[lomograb]

Yes, I have done succesfully install Caffe on my system. But I'm not sure this is installation issue. Correct me please

[lomograb]

what version of Protobuf do you using ?

[MhLiao]

I use the 2.6.1 version.

The only solution was dowgrade Ubuntu to Trusty Tahr which have gcc 4 as the default compiler. One more question: Could it be possible to reduce the recognition time ? I got 3 - 7 seconds for every execution
