Dude I think they gonna take your issue seriously

I saw they where discussing your issue on chat

I saw they where discussing your issue on chat

ohhh

can you send me the emails where they talked about?

I talked to you in a private chat

You can subscribe them on GitHub

You will get the mail

Actually I remember they have long term problem in this issue

There were many bugs related to napi and events loop

In version 11.0

ahhhh

i understand

I hope it will be interesting for them

I also have integrated node gyp in CMake

and other improvements, I don't know

I think it may be interesting for them

I think that should be instant ban

does any body here now? )

i participate in kaggle competitions and try compile top c++ kernel and have problem with compiler

i am absolutly novice with c++

i am absolutly novice with c++

Me too

Me too

sad

I'm happy because I'm learning 😬

Aren't kaggle competitions all for A.I.?

problem is that compiler return that function return value declared with attribute warn_unused_result

couse its kaggle santa

problem is that compiler return that function return value declared with attribute warn_unused_result

Oh i see. Post the original compiler complaints please?

one of kernels use c++

sec

kernel

In static member function static std::vector<int> santa::ArrayTourReadVec(const char*, int): dp.cc: 157:10 warning: ignoring return value of char fgets(char*, int, FILE*)`, declared with attribute warn_unused_result

In static member function static std::vector<int> santa::ArrayTourReadVec(const char*, int): dp.cc: 157:10 warning: ignoring return value of char fgets(char*, int, FILE*)`, declared with attribute warn_unused_result

OK that's not a problem.

any error?

no just this

Find the first error.

Find the first error.

does compiler must compile file with this warning?

does compiler must compile file with this warning?

You can turn off the warn_unused_result by some option. Generally speaking, if you're sure what causes the warning, then it won't be a problem.

Did it just succeed?

It should generate an executable file dp

i dont see dp file after compiliation

OK then there must be some `error`s reported by the compiler

w8 min plz

take your time 🙂

re-definition error dude

smoke manual? ^)

what's the exact g++ command you used?

its strange cause its public kernel what works well at kaggle server

!g++ --std=c++17 -Wall -g -Ofast -mtune=native -march=native -fopenmp -DNDEBUG -o dp dp.cc

Yes it's correct, but why multiple *.o files were generated?

What I saw was --

You copied and pasted some options for too many times

no its was once
