请问如何在Linux上编译源码?

[Igamegum]

我直接操作如下
1. cd ncnn 2. mkdir build && cd build 3. cmake .. 4. make

make 的时候报错如下
[ 90%] Linking CXX executable ncnn2mem [ 90%] Built target ncnn2mem make[2]: *** No rule to make target '../tools/PROTOBUF_PROTOC_EXECUTABLE-NOTFOUND', needed by 'tools/caffe.pb.cc'. Stop. CMakeFiles/Makefile2:179: recipe for target 'tools/CMakeFiles/caffe2ncnn.dir/all' failed make[1]: *** [tools/CMakeFiles/caffe2ncnn.dir/all] Error 2 Makefile:127: recipe for target 'all' failed make: *** [all] Error 2

需要先安装protobuf devel

少了protobuf-compiler

已解决，谢谢

install opencv for building example 的时候遇到这么一个问题：ncnn/examples/fasterrcnn.cpp:3:33: fatal error: opencv2/core/core.hpp: 没有那个文件或目录

已解决，谢谢

一样的问题， 请问是如何解决的？

Did anyone (@522730312, @creat2012) solve this issue? I am also getting the same problem of opencv2/core/core.hpp file not found.

make编译出现以下问题：
