I’ve been having success building out a pure CMake GUI app using the JUCE’s CMake setup instructions… until I tried to use AudioThumbnail.
For instance, these compile and build fine:
#include <juce_audio_formats/juce_audio_formats.h> #include <juce_audio_devices/juce_audio_devices.h> #include <juce_gui_extra/juce_gui_extra.h> #include <juce_audio_utils/gui/juce_AudioAppComponent.h>
But as soon as I add these:
#include <juce_audio_utils/gui/juce_AudioThumbnail.h> #include <juce_audio_utils/gui/juce_AudioThumbnailCache.h>
and declare them:
I get this compile error, followed by a series of follow-on cascade errors for
<path-to>/JUCE/include/JUCE-6.0.1/modules/juce_audio_utils/gui/juce_AudioThumbnail.h:50:44: error: unknown class name 'AudioThumbnailBase'; did you mean 'AudioThumbnail'? class JUCE_API AudioThumbnail : public AudioThumbnailBase ^~~~~~~~~~~~~~~~~~ AudioThumbnail
FWIW, CLion’s code navigation can find
juce_AudioThumbnailCache.h and I can see the file in
I have rebuilt the JUCE lib and my app multiple times, and I’m stumped how to diagnose this kind of problem where some of the lib files are not available. Is this an optional class in the JUCE distribution; is there an additional build flags I have to use when I’m building the JUCE lib?
