Crash when trying to connect to server

[Wuzzy2]

I can't get Soldat to run. When I try to run a local server and start the client to connect to it, first, the loading screen appears, and then both server and client crash at the same time.

I have followed the build instructions to build Soldat myself, and I managed to build server and client, but they don't work.

System information:

• OS: Linux 5.7.8 (Arch Linux)
• Pascal: FPC 3.2.0
• libGameNetworkingSockets: built myself, commit 8f60b0e (as recommended here: Questions about this repository prebuilt-libs#1 (comment))
• libstb: built myself in Soldat repository
• libphysfs: 3.0.2
• make: GNU Make 4.3

CRASH LOGS:

Soldat version: 078795a

[zenyd]

I'm not sure if this will help, but can you try compiling again with an older version of the fpc (3.0.4)?

[Wuzzy2]

OK, with FPC 3.0.4 it works!

FPC 3.2.0 has a lot of changes, it could be that they break things, see here: https://wiki.freepascal.org/User_Changes_3.2.0

Maybe you want to check out how to make Soldat work with FPC 3.2.0 as well? If not, I suggest to write in the readme that the EXACT version 3.0.4 is required (instead of the usual “this version or later”).

[zenyd]

if it won't work with 3.2, maybe it's some kind of compiler bug and needs reporting to fpc folks, so it can be fixed.

[Wuzzy2]

I have no idea.

The error messages look a lot like what I saw when having problems with the GNS bindings, but I believe those issues are resolved. Feel free to reopen if you experience this again.
