ubuntu - 构建 Caffe 时找不到 protoc 错误

Question

我正在使用 Ubuntu 16、Python 3、CUDA 10.1 和 Tensorflow 2.3。我在 Caffe github repo 上使用了 git clone，然后做了

cd build
cmake ..
make all

我收到了一堆 protobuf 错误:

~/Downloads/caffe/build$ make clean

我也试过

sudo apt-get remove libprotobuf-dev protofbuf-compiler
sudo apt-get install libprotobuf-dev protofbuf-compiler

接着:

conda uninstall libprotobuf
conda uninstall protobuf

但那些没有帮助。任何人都可以帮忙吗？

如错误消息中所述:您需要在 C++11 模式下运行编译器。尝试以 cmake -DCMAKE_CXX_FLAGS='-std=c++11' .. 运行 CMake .
