Why init() crashes for debug dll?

[jcyuan]

compiled 2 versions of shared dll: bgfxd.dll (debug) & bgfx.dll (release)
and in C# use #DEBUG to select dll to invoke.

but not sure why, for bgfxd.dll it alwasy crahses in the init call, it blocks there for about 2 seconds, and then crashes the whole app, but bgfx.dll (release) works well...

where can i find the crash log please? i have no clue where to start debug from.

btw, will bgfx.set_debug work for release dll too? if so, i think i don't need a debug dll maybe?

If you're on Windows, debug output goes to Visual Studio's Debug Output Window.

mmm, nothing there, i think c++ ouput won't get printed in the c# output window?
or maybe the init didn't print anything yet?
actually for release dll, the init blocks the thread a little (about 100ms or so), but it won't crashes the app.

more info:
I'm using AvaloniaUI as the main App (UI thread), and it creates DX11 (OpenGL ANGLE) as the backend,
after UI lunches (device created), i then initialize bgfx in a new thread, and bgfx.init blocks the new thread forever, after about 2seconds, App crashes. (release dll won't blocks there forever, but didn't test to see if the rendering output works or not, will try now)

btw, Blocking means my whole desktop, even i can't move my mouse! (release)

[jcyuan]

well...... the solution is really simple:

// type = bgfx.RendererType.Direct3D11,

remove this line from the init struct and let it auto select backend...... (which one gets finally selected, i don't know....), and then both release/debug dll works fine, no blocking anymore.

why i specify d3d11 is because AvaloniaUI OpenGL ANGLE uses d3d11, and i need to share texture with the UI (show bgfx main framebuffer on the UI)

why i can't use d3d11? because the device is occupied?

No clue, I would have to see repro code to understand what's going on.

You should run provided examples, and see if you have the same issue. If there is the same issue with examples then there is something wrong with your setup. If examples don't have the same issue then it's your code that causes it.

Try add: init.resolution.format = bgfx.TextureFormat.RGBA8;
