Trouble compiling Dolphin!

[Yoshimaster96]

While

Code:

cmake -DFASTLOG ..

works fine,

Code:

make

gives me this error:

Code:

What's going on?

[Yoshimaster96]

Sorry for the bump, but I want to know if this is the correct forum for this particular issue. If not, could someone move it to the proper place. Thanks! I wish to get this issue solved in a timely manner.

My operating system is Linux Mint 17.3 'Rosa' Cinnamon 64-bit, if that helps.

Looks like your system has an old version of libavformat. It builds fine here with version 3.2.5.

[Yoshimaster96]

Code:

sudo apt-get install libavformat-dev
...
libavformat-dev is already the newest version.
...

Um... what?
Also, what is libavformat used for? If it's only for video capture, I don't need that feature. If it's used in the emulator itself, disregard.

Add -DENCODE_FRAMEDUMPS=OFF to cmake's command line arguments to disable the video capture recording. (Seems it is only used for that)

Still asks for the library... Does anyone know how to install said library?

Sorry for the bump again, but, I can't seem to install it. Updating ffmpeg does nothing (if I'm doing it right that is). I honestly think there should be a guide on installing the dependencies, because it's not very obvious...

Have you tried following the "Building Dolphin on Linux" article? Should be fine to use the instructions for the latest Ubuntu.

Thanks! But, I have another error now:

Clean your build cache.

HAVE_FFMPEG may still be defined somewhere, causing that function to be defined twice.
