Error when compiling AudioClassifier app using VisualStudio #21

Closed Pems closed 5 years ago

Pems commented 6 years ago

Hello. So, I downloaded the latest version of openFrameworks as well as the ml4a-ofx repository, and used the Project Generator to create a Visual Studio solution for the AudioClassifier app. Next I got the addons that the app uses, and placed them in the addons folder. At first I was getting some errors with the GRT addon, but I realized that the ofxGrt repo didn't have the GRT folder that appears here, so I placed the folder inside the addon's folder and it solved the issue.

However, with the ofxMaxim addon I get another issue: I noticed the github repo links to another repo which contains the same addon, but updated more recently. I have tried copying both folders into the addons folder, but I get different results with each. I attach screenshots. I have tried merging the contents of both folders into one, but I still get errors.

This is from the falcon4ever repo: falcon4ever_ofxmaxim

And this is from the Maximilian repo: micknoise_maximilian

I haven't tried the other apps yet, but any help with this would be very appreciated.

can you get any of the examples working with ofxMaxim? this appears to be an issue with ofxMaxim, not the ml4a-ofx examples.

Hi. Well, kinda... I managed to make the ofMaximExampleVS2010 run, but it doesn't recognize the keyboard input. I got some errors at first, but they were due to being made in an erlier version of Visual Studio and openFrameworks.

Now, when I try to compile again the AudioClassifier app I get only this error: "Error LNK2001 unresolved external symbol "public: __thiscall GRT::FFT::FFT(unsigned int,unsigned int,unsigned int,unsigned int,bool,bool)" (??0FFT@GRT@@QAE@IIII_N0@Z) AudioClassifier D:\Open Frameworks\ml4a-ofx-master\apps\AudioClassifier\FFTFeatures.obj". I really have no idea what to make out of this, especially because when I browse the folder there's no FFTFeatures.obj file, which I'm asuming is part of the build process from Visual Studio... but beyond that I have no idea what could it be.

Do you have testimonies of people making it work on windows so far?

EDIT: Oh, reading the error, I notice the GRT. Could this be an issue with the GRT library? I only copied the GRT folder inside the ofxGrt folder, but I don't know if perhaps I should add or remove files from there?

it seems perhaps you didn't download the GRT libs with the submodule. see the instructions in the ofxGRT github page.

cd ofxGRT
git submodule init
git submodule update
