Default game hangs after launching the binary generated by make on cygwin

[lewis-carson]

A command prompt window opens, and then becomes unresponsive immediately.

[solenum]

I'm assuming this is Windows 10? Could you paste the make output and also any output you get when running the .exe. Also knowing your system specs might help.

Is this hang constant, or does it resume eventually?

[lewis-carson]

It never resumes, I have to force quit eventually.

I'm running windows 10 version 1809 and an nvidea 1050 with an 15 7th gen.

Here's what the command prompt window shows:

[solenum]

Oof, appears there was some whitespaced added to a file path in an older commit, should be fixed now. Could you confirm this for me?

[lewis-carson]

Sorry, still not working, same problem!

[solenum]

Rather difficult to debug without much to go on, I'm assuming your GPU drivers are up to date? Make sure you've pulled the very latest version of the engine with all the changes, run 'make clean' and re-run 'make' to get a new build.

Also try running the .exe from the Cygwin terminal (./game.exe) and from the Windows file explorer.

[solenum]

Wait, if I recall there's an issue with PhysFS on Windows 10 ver. 1809. There's been no new PhysFS release for a while.

Could you download this and extract it to src/lib/physfs (replacing all of the files), and do a full re-compile?

https://icculus.org/physfs/downloads/physfs-3.0.1.tar.bz2

I have no idea if the fix for 1809 is in that physfs release as it doesn't specify on when it was last updated, assuming it doesn't work for you I'll have to implement the fix myself.

Edit; I should specify, you need to extract the contents of the src/ dir in that tar.bz2 into src/lib/physfs, replacing all of the files in that directory.

[lewis-carson]

Unfortunately, this isn't working. When launching from cygwin it gives a seg fault and same as with the physfs patch. Have you any more possible fixes?

[solenum]

I'll need to update to build 1809 of Windows 10 myself and see if I can debug this, I'm sure its related to the physfs issue and I'm still not sure they've had a release yet that includes the fix for the API change in 1809.

The changes are listed below, if you want to attempt to modify the physfs source yourself to see if these fixes resolve the issue:

https://hg.icculus.org/icculus/physfs/rev/93b4c3bc6b9d https://hg.icculus.org/icculus/physfs/rev/ece6769c0676 https://hg.icculus.org/icculus/physfs/rev/ea88839fe34f

Edit;

Could you send me the compiled .exe? (Just the .exe, nothing else). I'll try it on my machine to confirm that the issue is in either the Windows version, or your hardware/driver setup.

[solenum]

After a lot of faffing about I finally got my Windows to build 1809. I can replicate the issue and I'm working on a fix at the moment :)

[solenum]

Alright I've pushed some changes, this should be resolved now. @torvim could you confirm this fix resolves the issue on your end?

[lewis-carson]

Sorry, I'm not at home at the moment, I'll be able to test in a few hours and confirm it for you.

[lewis-carson]

Sorry, still not working. Getting this (below), and then it hangs.

Loading config file data/conf.cfg Config variables: window_width = 1280 window_height = 720 Failed to initialize window Cleaning up scene

[solenum]

Well, that's progress. Could you post your (full) system specs please? And I'm assuming you're on a 64bit version of Windows? Including GPU driver versions if possible.

(Also are you on a laptop with a dual GPU setup?)

[solenum]

@torvim boop

[BenjaminGu]

I get the same error message.

[solenum]

@BenjaminGu Could you try changing argument 4 in glfwCreateWindow (src/exengine/window.c line 20) from NULL to 'glfwGetPrimaryMonitor()' and see if that resolves the issue?

- display.window = glfwCreateWindow(width, height, title, NULL, NULL);
+ display.window = glfwCreateWindow(width, height, title, glfwGetPrimaryMonitor(), NULL);

[BenjaminGu]

- display.window = glfwCreateWindow(width, height, title, NULL, NULL);
+ display.window = glfwCreateWindow(width, height, title, glfwGetPrimaryMonitor(), NULL);

I'm sorry. But, Still not working with the same error message.

[solenum]

Could you confirm that your system supports at least GL 3.3 and your GPU drivers are up to date?

I've just pushed some changes that add error logging for GLFW, could you compile/run the latest changes I have made and let me know if GLFW throws an error?

[BenjaminGu]

GLFW throws an error as follows.

GLFW ERR (65540)
Invalid window size 0x0

src/exengine/engine.c line 60 and 61

width = conf_get_int(&conf, "window_width");
height = conf_get_int(&conf, "window_height");

both conf_get_int return 0 conf_get_int function return 0 at exe_conf.h line 173.

I set the width and height as follows and run game.exe successfully.

width = 1280;
height = 800;

[solenum]

Huh, that's bizarre. The conf vars for the window resolution are indeed window_width and window_height, I'm surprised it worked with just width and height. I'll need to investigate the config loader and figure out whats going wrong. (Whole thing needs a re-write to be honest)

Strange that I can't replicate this on Windows 10 myself.

[solenum]

As of https://github.com/exezin/exengine/commit/a0919fc6f2900a12d099b12623805bbb62c064da the config loader has been replaced with a more robust ini-esque one, so I assume this issue is resolved.

Feel free to re-open if the issue persists for you.
