This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle.
Changing version to '24'.

More information and reason for this action is here:
https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora24#Rawhide_Rebase

lv2gui.cpp: In function 'void* extgui_instantiate(const _LV2UI_Descriptor*, const char*, const char*, LV2UI_Write_Function, LV2UI_Controller, void**, const LV2_Feature* const*)':
lv2gui.cpp:585:16: error: cannot convert 'bool' to 'LV2UI_Handle {aka void*}' in return
         return false;
                ^~~~~

See "Cannot convert 'bool' to 'T*'" in https://gcc.gnu.org/gcc-6/porting_to.html

I switched to NULL, which worked, and allowed me to get to this:

modules.cpp: In member function 'virtual bool calf_plugins::analyzer_audio_module::get_graph(int, int, float*, int, calf_plugins::cairo_iface*, int*) const':
modules.cpp:1430:74: error: no matching function for call to 'max(float, double)'
                                     fabs(fft_outL[_iter]) - var1L , 1e-20);
                                                                          ^

I know it's related to the <algorithm> header but I can't make out what I'm missing.

Ah, progress. . .

modules.cpp:1430:74: error: no matching function for call to 'max(float, double)'
                                     fabs(fft_outL[_iter]) - var1L , 1e-20);

That needs to be cast, e.g. float(1e-20)

I used that for make_pair, but for max I converted to >?:.

Thanks!
