codegen.cc:150:32: error: use of deleted function #4596

Not sure if it's correct, but I just adding line 18 to exclude the codegen.cc from default compilation. 18 if(USE_DNNL_CODEGEN STREQUAL "ON") |

According to this post, it seems like we triggered the stream move constructor that has not yet supported in gcc 4.8. We'll try to find out the root cause, although we don't have gcc 4.8 to reproduce the issue. The most efficient solution would be upgrading gcc version I think. btw, the solution @kevinyuan proposed could work, but it's just a workaround. |

Given that we do not really have to move the code generator class, I would say we can simply disable copy and move. If we need to move it, consider wrap it in an unique_ptr |
|
copy constructor is triggered by This should be fixed by #4597 |
