Just got back into Freespace after years of it just sitting on my GoG. Been back playing for a week, but now my Knossos.net is not recognizing the FSO build engine. It states that I need to download a FSO build to enable this setting.

I have the latest stable build of FSO 23.2.1 installed, but the Settings refuses to see it for whatever reason.

[wookieejedi]

Good question, from the screenshots I'm not sure why it might not be recognizing it. If you are able to I recommend asking on the Knossos Discord subchannel (link here: https://discord.gg/xckku4bgxB). The Discord channel allows use to very quickly help troubleshoot. If you are unable to join the Discord though just let us know and we can continue troubleshooting here, thanks!

[Sevanti]

Well, I did not manage to solve the issue with Knossos.net. However, using Knossos, I was able to get the game running once more. Silent Threat was an issue, and I had to go back to the 1.7.1 version of ST:R to get it to work without erroring.

I think I have a similar issue. After playing Wing Commander and the X-Wing trilogy, the next logical step is for me to try Freespace 2 (GOG version). I installed Knossos.net 1.0, but unfortunately, the download of any version of a FSO build is not detected by Knossos, and several options of the "settings" panel are not available. I also cannot launch the Freespace upgrade media/VP or any others mods.

The downloading is marked "complete!", the decompression step stays at 100 %, and there is nothing for "getting tile image" and "getting banner image". The FSO build seems to be correctly installed inside the "Library" folder. I tried to deinstall/reinstall everything, without any effect.

Any help or advice will be appreciated

I have to admit that I am not a user of Discord, and English is (clearly) not my native language, so if you could help me through this forum that will be wonderful.

[wookieejedi]

Sounds good. First off, are you on Windows? 

[Pikaia]

Yes, I am on Windows 10 Pro 22H2.

Edit : two screenshots of my issue. The first one shows the "settings" panel. The build downloaded and installed is recognized by the stats, but several options are grayed or not available (error message in red : "first download a FSO build to enable the setting").

The second shows what happens when I download a build : the downloading appears to be complete, the decompressing is at 100 % (and the files are on my disk), but there is no tile or banner images.

[wookieejedi]

Thanks for the screenshots. Can you also show screenshots of your knossos library folder, specifically the `bin` folder, which is where the FSO builds are downloaded.

Also do you get the same error if you try downloading FSO version 23.1?

[Pikaia]

A screenshot of the bin directory, and a maybe more convenient DOS listing of the files. I unfortunately also have the issue with the FSO 23.1 version.

Thanks, to me that all looks reasonable. Could you also upload your Knossos Consoloe File (Debug tab in Knossos)? 

[Pikaia]

The Knossos console file upload link : https://fsnebula.org/log/65e08c9cd85c7c3f3ec9d0b6

These lines are maybe linked to my problem :

*Error* : (FsoBuild.GetFlags()) The input does not contain any JSON tokens. Expected the input to start with a valid JSON token, when isFinalBlock is true. Path: $ | LineNumber: 0 | BytePositionInLine: 0.
*Error* : (FsoBuild.GetFlags()) The input does not contain any JSON tokens. Expected the input to start with a valid JSON token, when isFinalBlock is true. LineNumber: 0 | BytePositionInLine: 0.
*Error* : (FSO EXE OUTPUT )

[wookieejedi]

Thanks, I checked with one of our advanced developers, who thought perhaps the system does not actually support AVX builds even though those are being autodetected. Can you try to download and set a nightly build instead? (Nightly builds are SSE not AVX). 

[Pikaia]

I have unfortunately the same issue with the nightly build (with the same errors in the console log). I tested lot of builds, without any success so far. Not sure if it could help, but my gaming rig is quite recent (even if I use it a lot for retro-gaming !) : i7-12700, RTX 4080, 32 Go RAM, M2 SSD.

[wookieejedi]

Thanks for that clarification. At this point I'm not sure what may be causing it. But running FS2 through GoG does currently work correct?

[Pikaia]

Yes, I am able to launch and play Freespace 2 through GoG.

[wookieejedi]

Good to know. In Knossos, can you go to the Home tab, hover over the Retail Freespace 2 tile, click Settings, then click browse, and manually browse and select a build? Once you have selected a build then click the Save button and close the popup Settings window, then try running the game.

[Pikaia]

When I do that, the game (Freespace 2 retail) crashes (I tried different builds), and a dump file (*.mdmp) is created inside the FSO build folder.

[wookieejedi]

Thanks for the update. Can you try manually browsing and running to a debug build and then posting the log on a nightly build?

Hello everyone,

I seem to be having a similar problem, difference being Im on Ubuntu (22.04) Linux.

Here is my log, short version - this repeats each time I try to launch. Also, I get red text in Knossos settings all the time: "First download a FSO build to enable this setting"
It is downloaded. Tried nigthly or RC builds, result is the same. The files and folders themselves are there after download. I even modified permissions for them to be sure.
Launching the .AppImage files directly deos nothing.

Any ideas please? Thanks!
