What is this? how do I fix this?

Sounds like your server.dll wasn't built. You can double check it by going into the server folder and checking the Release folder, and look for server.dll.

In the event that server.dll didn't build, highly likely because you did not have python installed to generate the necessary vscript files

Thx

[KeylimeDreams]

I keep getting errors like'g_Script_spawn_helper': undeclared identifier & 'g_Script_vscript_server': undeclared identifier

Install python 3, verify that the folder it's installed to is in your PATH environment variables, then clean the solution and rebuild

#635 goes over this

@AnOldLady where can i find server.dll ? i've been searching this on the whole vs solutions but there is nothing to find, and i have a bug for the server spawn, the #635 didn't helped me so much to fix that

[NepJr]

Did you actually verify python works in cmd by opening a cmd terminal and typing python?

Also did you make sure to clean the solution and rebuild?

[Abdoujumper]

no but i will, thank you, if there is an error ima inform y'all here !

I'm having a similar issue with the error:

Exception thrown at 0x0000000000000000 in hl2_win64.exe: 0xC0000005: Access violation executing location 0x0000000000000000.

With the call stack:

 	ntdll.dll!00007ffddcd5c34c()	Unknown

I can see both client.dll and server.dll in game\mod_hl2mp\bin\x64 with correct modified dates.

Without the PDB for the engine.dll I don't know how to investigate this further. Could you please help? Thank you in advance.

Edit: Update to this: A lib linked in the project was failing to initialise due to missing dependencies - fixing it solved the issue :)
