[Anagh Rao]

I am not able to install caffe on my macbook pro I do not have an external GPU and followed the instructions acc to this link : https://gist.github.com/doctorpangloss/f8463bddce2a91b949639522ea1dcbe4

And when I am trying to run the command $ make

I am getting about 20 errors and I dont know what to do. 

fatal error: too many errors emitted, stopping now [-ferror-limit=]

46 warnings and 20 errors generated.

make: *** [.build_release/src/caffe/proto/caffe.pb.o] Error 1

Pls suggest what to do.

Dear Anagh,

Please try following things to debug the problem:

1. Make sure you have protobuf compiler installed
2. Make sure the config file, i.e., Makefile.config is correct 

PS: Please show us complete errors reported at the console. You may copy the whole console, after invoking make.

Regards

Ravi

I'm also running into issues with installing Caffe on my Macbook Pro (Catalina v10.15.1).

I tried building from source, and encountered a number of errors in the protobuf compilation, most of them related to C++11 extensions.

(I have the later versions of clang++ v11, and g++, so I'm puzzled by these warnings...)

Makefile.config, is set to CPU-only mode, and the remaining configs are default.

No receipt for 'com.apple.pkg.CLTools_Executables' found at '/'.

Hi, it seems like you need to change your Makefile (not Makefile.config) 

there is one line like this: CXXFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS)

and you should try to change it like this: CXXFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS) -std=c++11
