Hi everyone, I'm trying to compile caffe 2 but despite I followed all the instruction I finally get this error.

[ 16%] Building CXX object third_party/gloo/gloo/CMakeFiles/gloo.dir/context.cc.o In file included from /home/marco/caffe2/third_party/gloo/gloo/context.cc:12:0: /home/marco/caffe2/third_party/gloo/gloo/common/error.h:25:46: error: expected class-name before ‘{’ token /home/marco/caffe2/third_party/gloo/gloo/common/error.h: In constructor ‘gloo::Exception::Exception(const string&)’: /home/marco/caffe2/third_party/gloo/gloo/common/error.h:27:66: error: expected class-name before ‘(’ token /home/marco/caffe2/third_party/gloo/gloo/common/error.h:27:66: error: expected ‘{’ before ‘(’ token make[3]: *** [third_party/gloo/gloo/CMakeFiles/gloo.dir/context.cc.o] Error 1 make[3]: Leaving directory /home/marco/caffe2/build' make[2]: *** [third_party/gloo/gloo/CMakeFiles/gloo.dir/all] Error 2 make[2]: Leaving directory /home/marco/caffe2/build' make[1]: *** [all] Error 2 make[1]: Leaving directory /home/marco/caffe2/build' make: *** [all] Error 2 ` Can someone help me?

P.S. I tried also to configure the make file in other way but without succes.

Thanks. Caffe2 needs GCC 4.9 or higher to compile. Which version of Ubuntu are you using?
