python - OpenPose:体系结构x86_64的 undefined symbol :libcaffeproto.a(caffe.pb.cc.o)

Question

在openpose安装期间，将安装依赖项。
使用-make -j nproc进行构建时

我收到以下错误:

[  3%] Built target caffeproto
[  3%] Linking CXX shared library ../../lib/libcaffe.dylib

[解决]

这基本上是由于CmakeList.txt和可用的protobuf编译器版本不同而引起的。

如果您遇到此问题，请尝试删除过时的问题。

即使它不起作用，也可以使用

protoc src/caffe/proto/caffe.proto --cpp_out=.
mkdir include/caffe/proto
mv src/caffe/proto/caffe.pb.h include/caffe/proto
