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!

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

@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)

/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

/Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/libusb-1.0.so: is not an object file

@didipiman Hm.

Try:

install_name_tool -id /Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/libusb-1.0.so /Applications/Pd-l2ork.app/Contents/Resources/app.nw/extra/pd_helios/libusb-1.0.so
