Isn't this an issue with the compiler header files?

In any case, los heavily depends on ALSA. It won't work on FreeBSD.

Isn't this an issue with the compiler header files?

I will ask experts, but clang on BSD builds hundreds/thousands of projects, so simple silly bugs preventing valid code from building are usually not found. But I will ask.

In any case, los heavily depends on ALSA.

No way to untangle and make it work with Jack?

falkTX commented 6 years ago

It already works with JACK, but ALSA is the one driving the engine. Since this is a minor project for me, there won't be major refactors to the code. Will be just Qt5 update and fixes here and there, to make it usable for me and a few others.

This is a pure-MIDI sequencer, it doens't do much. Likely you want something else. But for me, wanting something simple and quick, it fits a place in my "tool-box".

Note: the build issue is likely related to C++11 and Qt4 being mixed.

Looks like something is defining __invoke, and then including the C++ headers. That should be avoided, any identifiers starting with _ are reserved.
