如何编译caffe2ncnn工具

[LiMilo84]

我在ubuntu上编译caffe2ncnn.cpp的时候一直编译不成功，头文件都已经添加了。请问还有什么需要特别注意的地方吗？

[nihui]

错误是什么呢

[LiMilo84]

打印的错误信息：
#error This file was generated by a newer version of protoc which is
#error incompatible with your Protocol Buffer headers. Please update
#error your headers.

应该是生成caffe.pb.h的PROTOBUF版本问题吧？

[nihui]

系统里有两个 protobuf ?
把 protobuf 卸载重装下，然后删除 build 重新编译

## 这是什么错误呢？修改platform.h.in 为platform.h 里面三行换为#define XXX true

[akbarxie]

遇到和楼上大叔同样的问题，求解？？

[nihui]

用顶层的 CMakeLists.txt 编译....
编译完在 ncnn/build/tools 里头有

现在报出一大堆这样的错误
