FL Studio Debug/release

[JonOsterman]

Hi,

I'm experiencing something strange, I might have missed something.

In debug mode with FL Studio (on Windows) my plugin works well (even with Ctrl+F5), but if I launch first FL Studio and launch my plugin as if it was a release version it is telling me :
"Something went wrong loading the VST3 plugin. Please make sure it's installed and registered properly."

I've tried some solutions foundable on Google/StackOverflow but nothing works

Well I might not be in the right place for my problem, do you know where I could find help ?

Check your code very carefully for :

-Uninitialized variables (and class members)
-Logic errors that might lead to things like functions not returning anything when they should

In some cases the optimizations the compiler does for release builds can blow up the running code when the code has problems like the above.

If additional threads are involved, the timings will be different for debug and release builds. Release builds may more easily reveal problems related to multiple threads manipulating shared variables in an unsafe manner.

Are your CPU and the CPU instruction set release build settings compatible?

Sometimes just doing a full clean and rebuild of the project can solve mysterious problems.

I got 0 errors or warning, unless "float to int conversion"

I did not express myself well, what happened is that if I want to load in FL Studio (just launching the FL.exe without Visual Studio) the same vst file that I build in Debug Mode, it is showing me the sentence above.

Is there dependencies that Visual load in debug mode that I need to give to FL studio with my vst ?

I've cleaned, rebuild all and reinstalled FL Studio

Are you testing on the same system where you have Visual Studio installed? If yes, the Visual Studio dependencies for both debug and release builds should already be installed and available. But just in case that has been messed up somehow, you could check if changing the runtime library into statically linked helps. (You might want to statically link the runtime library anyway, to save your users the headache of the probably missing runtime dlls.)

edit : Sorry, I missed in your original post the part about "as if it was a release build".

Yes, basically I just copy/paste the vst file into the FL Studio's VstPlugins folder, as my Visual Studio post-build command does

I've already linked all my lib as static libs

that's a real conundrum here

Well, I tried to comment all my work, piece by piece, method by method, until reaching the IPlugEffect template and it doesn't worked.. Then I Cut/Paste my commented work in a text files to clean my cpp/h files without losing my work and then it worked

I tried then to reimplement my work piece by piece and when I got the same bug I commented what I added but it still wasn't working.

I do a
"cd $(VST3_32_PATH)
del *.vst3"
before each build (in "Pre-build event") so maybe it is FL Studio which store some presets somewhere ? I don't want to look ahead to a Visual Studio bug ..

EDIT : I deleted FL Studio VST3 presets, that did not fixed the problem

EDIT2 : I became crazy and started to remove the files from an SDK I need one by one, it was one of them.

For now I don't know why but I will find out and post here if it makes sense.
