Project built on Windows 10, with CMake/VS 2019. it seems to crash on calling std::string::clear(). when trying to obtain a crypto key.

0.0.0.0 is not the right address to connect to your server. 0.0.0.0 means "any local IP" and it's a valid thing to use when listening, but not when connecting

127.0.0.1 is the right IP to connect.

I'll see what is causing that assert, but I suspect it is downstrram of that.

I tried to connect to my server with 127.0.0.1 but the error still pops up.

Nope, I haven't seen that one! I'll see if I can reproduce it. Is this a debug build or a release build?

Just had an idea. Is the Windows firewall prompt coming up and stalling any of the socket calls?

Also, can you explain briefly how do I link a new project with this library ?

Ah, ordinary (non-CMake) Visual Studio projects. That's something I know about! (I really don't know anything about CMake). For that, you would just link with the import library GameNetworkingSockets.lib and have the .dll nearby your executable when it runs.

I got the error mentioned when I tried to run the example_chat.exe, the one created after building the project as explained in BUILDING.md.

After that, I tried to build the example on my own in a VS project. On debug as well as on release, the client crashes on line 529: m_hConnection = m_pInterface->ConnectByIPAddress(serverAddr); with Access violation reading location; It seems that m_pInterface is a null pointer.

Same Error
any Updates about this Error how to fix it?

from gamenetworkingsockets.

I had the same error, it occurred because I mixed debug and release builds (my OpenSSL & protobuf were release builds, while my GameNetworkingSockets build was a debug build), so make sure you are building all your dependencies and GameNetworkingSockets with the same build type. I guess it's the same with #54.

Nice yes that worked for me
Thank you very much :D
