Unable to build ff_meters with latest version of Juce #12

Open mediawizrd opened 4 years ago

mediawizrd commented 4 years ago

I get errors on the following header files when I try to build ff_meters using the latest version of the Juce library:

include <juce_audio_basics/juce_audio_basics.h>

include <juce_gui_basics/juce_gui_basics.h>

include <juce_events/juce_events.h>

Thanks for using ff_meters.

Do you mind sharing a little more detail?

I must admit, that currently I don't have an active project using the meters, but I'm still happy to fix it, if we can get to the bottom of it.

I tried and didn't have a problem. If it was related to issue #13 this should be fixed now. Can you please try again? (you will need to resave with Projucer or use whatever method to update your project files)

Hi Daniel

I am attaching my build log.  These sorts of errors seem to occur every time I try to include the  ffAudio/ff_meters module in my build.  I am having trouble building the code with both VS2017 and VS2019, when I use the latest (production) release of Juce (Version 5.4.7)..

Yes, a buildlog would help massively. Unfortunately your attachment didn't go through, I guess github doesn't support attachments. Just copy it in the post...

Thanks!

I am pasting the build log errors in below.

Oh, I see. I wasn't aware that maybe_unused is a C++17 feature. You can easily fix that by switching your project to C++17, but I will move back to use ignoreUnused() so you don't have to switch just for that feature...

Thanks for the report
