Visual Studio CMake errors

[jwalway]

Hello,

I'm getting CMake errors.

Some details:

I'm using the most recent build, I assume. I cloned the repository today. I'm not sure where to find the build version number. I looked around for it on this github repository.

I'm on Windows 10, 64-bit

Graphics Card: AMD Radeon (TM) R9 380 Series

I was following the Visual Studio building instructions on the front page: https://github.com/mgba-emu/mgba

I installed these: vcpkg install ffmpeg[vpx,x264] libepoxy libpng libzip lua sdl2 sqlite3

and I installed these: vcpkg install qt5-base qt5-multimedia

This took about four hours total. I think that all went well.

I then used Visual Studio to clone the project from here https://github.com/mgba-emu/mgba.git. That worked fine.

Finally, I got to the CMake part and in Visual Studio it gave the output I show below.

It says it couldn't find the epoxy module. It says "Windows requires epoxy module!" I don't normally use CMake to build Visual Studio projects. I mean, I have used CMake on the command line, but not within Visual Studio. I also assumed this would be 32-bit build. VS seems to want a 64-bit build.

I wonder if anyone knows what I'm doing wrong here.

Make sure to run vcpkg integrate install: https://vcpkg.io/en/docs/users/buildsystems/msbuild-integration.html

Thanks. I did this, but it didn't change the results. I assume the big problem is it not being able to find the epoxy module?

[jwalway]

I've been studying CMake in an attempt to figure out how to fix this problem, but as yet I've not discovered the answer. There is a function in CMake called "find_feature()". As you can see by the output in my first post above, that's where it is failing. I tried to find a CMake function called "find_feature()", but I have not been able to.

Anyway, I'd be grateful if anyone has the answer to this. I'm still studying it.

Thanks! ...John

It sounds like the root issue is just that Visual Studio can't find vcpkg. Take a look at this article too: https://vcpkg.io/en/docs/users/buildsystems/cmake-integration.html#visual-studio

Thanks for your reply. I turned out that Visual Studio defaulted to a 64-bit configuration for CMake. So, I had to figure out how to change it to 32-bit. I ended up going through a long tortured path to figure out how you create projects with CMake through Visual Studio. I learned that they have a filed named CMakeSettings.json. I had to then figure out how to change the settings to a 32-bit build (since all of the libraries downloaded were 32 bit). However, along the way I learned that there is a new system that uses a CMakePresets.json file. I played with this for a while, and after some headaches there decided to go back to CMakeSettings.json to try and get to the end point faster.

Well, I got there and it compiled!!

However, when I load a game into the emulator it freezes.

What's the audio driver set to? You're not the first person to report this problem.

I downloaded binary for the emulator and it works great, so it's something with my build. Unless you are referring to a setting within the emulator?

I'm going to try again tomorrow. I downloaded the zip file to build. Tomorrow I'll clone from github.

[endrift]

I do mean a setting in the emulator itself, yes.

Thanks! I'll look at that tomorrow.

Hello, I have the audio driver set to SDL.

[jwalway]

I did try the Qt Multimedia... It didn't work either. It took a little longer to freeze. The executable download works fine with SDL and OpenGL. So, I'm going to try a rebuild and see if there is something I can do there.

[jwalway]

Update... I cloned the project and built it again. I don't think I did anything different that I could see. However, I was able to load the game (Pokemon) and run it.

It did want the SDL2.dll (as did the other one I built). This time I also included the SDL2.pdb file, since this is a debug build. Maybe that's why this one worked better.

It felt a little touchy and the noise was garbled, so it feels like something is still amiss.

CMake doesn't build a Visual Studio.sln project file, as well. So, this way of building within VS is new to me.

I have the same issue as @jwalway mentioned above. Until now, I can not build it successfully. Cmake outputs "Windows requires epoxy module!" although I installed libepoxy before (vcpkg install libepoxy:x64-windows) @endrift Did you build successfully mGBA on VS 2019 before?

Please take a look at the solution for that I already posted here: https://github.com/mgba-emu/mgba/issues/2591#issuecomment-1188511836

@endrift, Thank you for your support. I built successfully on VS 2019 but I can not debug. I get an error as follows: Do you have an idea for this issue? Thank you.

[endrift]

Never seen that before. I have some testing I need to do soon, I'll be updating this thread as I do that.

[uocnx]

@endrift, I have fixed it as: https://stackoverflow.com/questions/55175387/unable-to-start-program-access-is-denied#:~:text=It%20is%20because%20you%20didn,This%20will%20solve%20your%20problem. Thank you.

@endrift, I am now debugging mgba.exe with mgba.dll library in visual studio 2019. However, I can only debug mgba-qt project and can not debug through mgba.dll which includes .c files to see something more deeply (breakpoints I set on .c file never hit). I also check some guides on internet but I have not found any solution. Can you help me now? Thank you so much.
