This symbol is defined in JUCE/modules/juce_audio_processors/format_types/juce_VST3PluginFormat.cpp. So why doesn't the linker find it?

[probonopd]

As a workaround, disable JUCE_PLUGINHOST_VST3 in Projucer under juce_audio_processors, and enable JUCE_PLUGINHOST_VST. Also see #3.

I built Projucer from the develop branch https://github.com/juce-framework/JUCE/tree/develop. It seems to run well on FreeBSD, and it seems to be able to produce "Linux" (read: GNU Makefile) targets.

However, it seems like for FreeBSD one has to use a special VST3 SDK that is compatible with FreeBSD.

But when setting "JUCE_CUSTOM_VST3_SDK" to "Enabled" in Projucer and entering /usr/local/include/vst3sdk under "Header Search Paths", then I get:

What gives?

[probonopd]

When I change the JUCE path and JUCE modules path in Projucer to the FreeBSD-provided /usr/local/include/JUCE-7.0.3, then I get:

[probonopd]

Maybe @yurivict knows?

[yurivict]

I just updated the devel/juce port to 7.0.5 - please try to build with it.

[probonopd]

Thanks @yurivict. Does building the 7.0.5 port with the examples (make config, check the checkbox) work for you?

[probonopd]

With the JUCE 7.0.5 port, when setting "JUCE_CUSTOM_VST3_SDK" to "Enabled" in Projucer and entering /usr/local/include/vst3sdk under "Header Search Paths", then I get:

Similar when I git clone https://github.com/steinbergmedia/vst3sdk/ --recursive and use that path.

@yurivict had you succeeded in building this repo, or just generally asked me to try 7.0.5? In any case, thanks for your help. I really appreciate it.

The relevant patches were in this PR created by me: https://github.com/juce-framework/JUCE/pull/881

They closed it because they merged some other BSD patches, but the ones relevant for demos were left out, particularly in modules/juce_audio_processors/format_types/VST3_SDK/pluginterfaces/base/fplatform.h.

I just don't have time to resubmit patches over and over again.

I asked JUCE maintainers to merge remaining patches.

vst3sdk has no install target (https://github.com/steinbergmedia/vst3sdk/issues/77), so users are reluctant to integrate it properly, or just copy it in, instead of doing something like find_package(vst3sdk). JUCE has some portions of vst3sdk copied in but it appears to be broken, or incomplete or outdated.
