Socket.cpp | Easy C Socket Class | Socket library

I have been working on a C++ project which depends on RPLidar SDK. I have already installed the SDK as per the instructions in the README. (FYI: I couldn't install it in the /usr/local/ directory using sudo make install command). As per the SDK documentation:

When developing via RPLIDAR SDK, developers only need to include SDK’s external header files (under sdk\include) into their own source code and link the application with SDK’s static library (rplidar_driver.lib or rplidar_driver.a).

So, in my CMakeLists.txt, I have already added:

I have this makefile:

I am currently running Azerothcore via docker on my centos 7 server. I am trying to update it with the updates since i originally set it up.

current docker version: Docker version 19.03.12, build 48a66213fe

current docker-compose version: docker-compose version 1.18.0, build 8dd22a9

Here is the build command i ran: ./bin/acore-docker-build

When i run the docker build command i am getting the following errors:

I'm getting undefined reference to dlsym@@GLIBC_2.2.5 even after linking it before and after the libraries. However in the linking output it appears that it's linking just before, but linking before all libraries should work, I guess.

I have problems connecting to my TCP server socket. I have had it working before, but after adding threads I had problems compiling it with just g++ main.cpp, and had to use a higher version, and after that it won't connect. The threads should really not mess with the execution of TCP connection. And it seems that it could be a compiler version or flag which is missing that could be the problem, but I'm not sure.

I have the firewall disabled, and have also tried with firewall on and accepting connections, but with no luck.

My client is returning the perror "Connection refused".

Wireshark packets show only two packets, which makes sense since the handshake is not complete.

I compile the server with g++ main.cpp -std=gnu++2a -pthread and run it with ./a.out, and compile the client with g++ testClientSocket.cpp -o testClient -std=gnu++2a -pthread and run it with ./testClient

The server is called in another file with code:

I have a library which uses templates very much to avoid rewriting the same code many times . But as known this leads to horrible compile times and in visual studio also leads to heavy and slow intellisense which makes coding on a computer with 4 GB of ram very noisy .

However most classes are designed so that they only can be instantiated with particular types and templates are there to avoid rewriting for each type , this made me move most of the implementations to .cpp files and use explicit template instantiation there .

For example I have :

I have a vector of unique_ptr for an ethernet_socket class. If I reset the pointer, I am seeing the constructor called first in my logs before the destructor. Is this right, or is my boost logging lagging?

I'm following the guide from:

I'm having issues at the very last instructions under "compiling on windows" where I am asked to move a series of DLLs to a folder called CMAKE_INSTALL_PREFIX. I cannot find this folder, despite getting no errors from the compiler? visual studio I don't think things are building properly.

I get 3 warnings when compiling in visual studio,

Warning LNK4221 This object file does not define any previously undefined public symbols, so it will not be used by and link operation that consumes this library scripts Build\src\server\scripts\zone_alterac_mountains.obj 1

Warning LNK4221 This object file does not define any previously undefined public symbols, so it will not be used by any link operation that consumes this library scripts \Build\src\server\scripts\zone_burning_steppes.obj 1

Warning C4715 'WorldSocket::ProcessIncoming': not all control paths return a value game c:\users\frith\azerothcore\src\server\game\server\worldsocket.cpp 727

I've restarted the entire process a few times and have made no progress. I'm under the impression I should see something in the destination folder, it is empty.

After some digging I found this in an error log in build/CMakefies

\Build\CMakeFiles\CMakeTmp\CheckIncludeFile.c(1): fatal error C1083: Cannot open include file: 'pthread.h': No such file or directory [\Build\CMakeFiles\CMakeTmp\cmTC_0e035.vcxproj]

I'm totally stuck.

I am trying to create C++ socket client for python server. Because I am new to C++ before creating the C++ client I checked if the python socket server with python client. After creating and running the C++ client the server do not get any connection
