Hello,

I'm struggling to install the helios external library (https://github.com/timredfern/pd_helios) in Purr-Data on a mac running 10.15.6
I think I managed to build the library (it created a darwin file) and i moved the whole folder to

/Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios

My startup preferences have that same path in the search path window and "helios" in the libraries one. but when i open Purr-Data i get "helios: can't load library"
What obvious thing am i missing? I have not used Pd in years...

I also tried copying the helios folder to /Library/Pd-l2ork and adding that path to the search path preferences, to no avail.

THANKS ALL!

@didipiman What happens if you type this in an object box and try to instantiate it:

/Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/pd_helios

Also, what's the output if you run this command in a terminal:

file /Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/pd_helios.pd_darwin

the object won't create

and the output of the terminal is:
/Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/pd_helios.pd_darwin: cannot open `/Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/pd_helios.pd_darwin' (No such file or directory)

Oops, try instantiating:

/Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/helios

mmmmm sadly still no luck. red dotted line object...

Any errors printed to the Pd window?

yes, a ton
too many to paste. should i look for anything in particular?

anything about missing symbol

i don't see anything about a missing symbol printed there...

Also try this in the terminal:

file /Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/helios.pd_darwin

/Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/helios.pd_darwin: Mach-O universal binary with 2 architectures: [i386:Mach-O bundle i386] [x86_64:Mach-O 64-bit bundle x86_64]
/Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/helios.pd_darwin (for architecture i386): Mach-O bundle i386
/Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/helios.pd_darwin (for architecture x86_64): Mach-O 64-bit bundle x86_64

Back to instantiating this in an object box:

/Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/helios

Does any of the output in the Pd window have the word "succeeded" in it?

yes, twice (tho they look identical):

tried /Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/helios.pd_darwin and succeeded

tried /Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/helios.pd_darwin and succeeded

@didipiman Hm, it shouldn't print it twice. What are the errors after the 2nd one?

pasting the next few lines, though there are many more after this:

tried /Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/helios.pd_darwin and succeeded
verbose( 1):/Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/helios.pd_darwin: dlopen(/Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/helios.pd_darwin, 10): Library not loaded: @rpath/libusb-1.0.0.dylib

a

@didipiman Ok. What's the output of this:

otool -L /Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/helios.pd_darwin

/Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/helios.pd_darwin:
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1281.100.1)
@rpath/libusb-1.0.0.dylib (compatibility version 1.0.0, current version 1.0.0)
/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 902.1.0)

@didipiman And now this:

otool -D /Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/helios.pd_darwin

/Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/helios.pd_darwin:

@didipiman How about:

otool -D /Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/libusb-1.0.so
