As a beginner, I want to use oat++ as a third-party library in visual studio, but I encountered some configuration problems.
First I downloaded the source file of the oat++ project and opened it in visual studio and cmake

->configuration properties
->VC++ Directories
- set the
Include Directories
includeC:\Users\13925\Documents\cpp\oatpp\out\install\x64-Debug\include\oatpp-1.2.5\oatpp
That is great. The compiler can find the #include "file"
After that I'm having trouble,An error occurred when I tried to compile.
...ANSWER
Answered 2021-Apr-09 at 02:14As far as I'm concerned, the problem is you are not linking against the Ws2_32.lib library. To fix this you could try to add that to your additional dependencies tab of linker/Input settings for your project. And you could also try to add: #pragma comment(lib, "Ws2_32.lib")

QUESTION
We are currently using Oat++ (https://oatpp.io/) as a webserver for an embedded project. It is working wonder with several environments: docker container, ubuntu VM, Raspberry Pi 3.
However, for this project we have our own linux distribution built with Yocto (https://www.yoctoproject.org/) and after some debugging, we realize that the getaddrinfo
(http://man7.org/linux/man-pages/man3/getaddrinfo.3.html) function is not working.
Here's a sample code of what is happening:
...ANSWER
Answered 2020-Jan-15 at 16:38Well, we found that the problem was not with getaddrinfo... Sorry for that.
The problem was because of IPv6 (the implementation of SimpleTCPConnectionProvider for linux is only using INET6) and our system is built only with IPv4.
So I created my own ServerConnectionProvider that implements a socket with INET instead of INET6.
