abel
that's the error message
Danya🔥
Probably because VS Code know nothing about how you run CMake
Danya🔥
Google how to change cmake settings in VS Code
abel
what's means that
abel
you mean this:"Adding the following to your workspace settings.json will make CMake Tools automatically use vcpkg for libraries"?
abel
that's the sentence in official guide
Danya🔥
So why don't you follow it?
abel
and i follow this guide
abel
it ask me to add
"cmake.configureSettings": {
"CMAKE_TOOLCHAIN_FILE": "C:\\src\\vcpkg\\scripts\\buildsystems\\vcpkg.cmake"
},
into the settings.json, and i did it, but it still have error
abel
err, i don't know how to say, but just now, i clean the cache, and build it again by same method
abel
and it worked
abel
but, why?

You are using Ninja Generator in the latter case and Visual Studio generator in the former case. So two different use cases. Do you have Ninja installed in your system? If not, you can use the Visual studio generator using the -G flag. CMake is a build generator and you can use it to generate builds for Ninja, Make, solution file for Visual Studio, Meson etc etc.

Guys, i am digging into nginx source code. I am wondering why author has chosen keeping sentinel for red-black tree outside of struct ngx_rbtree_t itself? Why not just to keep it inside of ngx_rbtree_t

The aes file is coded correctly but I still get the error and in the source code I added directory of the aes.h file but still getting the error

This is a linker error. Why are you passing a header file to the linker?

I have no idea what you are doing. A linker should be passed things like object files, dll files, lib files etc. The linker doesn't need header files. So I guess you either have the wrong configuration on your IDE or are just doing things plain wrong. Read up about your IDE/compiler before beginning to use it

If you kept them inside a tree node, then every node must store information on whether it is a sentinel or not. Granted you could just check the children nodes to determine if something is a sentinel or not. But keeping it outside makes some algorithms like deleting easier as you just have to iterate through the sentinel nodes rather than through the entire tree.
Also keeping it outside can help in ensuring that they always remain black.

You didnt get my question. I understand why sentinal is useful. Why is it kept outside tree structure? And i didnt ask why it is kept outside tree node but tree

Hi guys! Anybody can help me understand this code:
st = set_intersection (set1, set1 + 6, set2, set2 + 6, v.begin());    
v.resize(st - v.begin());
This program make intersection between vectors. Yet solved, but i can't understand this part the code. exactly in the resize function

set_intersection does not modify the size of container v, While resize actually modify the size of v

Set_intersection will return the first element that is not part of the intersection after reordering the vector to make that valid, you can then resize the vector to clean up and only keep the intersection in the vector
