David, thanks so much!
I´ll try asap with those files!
☺️

Hey @whale-av,
thanks so much for the answer, sounds pretty legit. however I tried and i am still getting the same answer without the double slash:

pd_helios-master % make PDINCLUDEDIR=../pure-data/src
ls: ../pure-data/src/m_pd.h: No such file or directory
++++ info: using Makefile.pdlibbuilder version 0.5.1
src/pd-lib-builder/Makefile.pdlibbuilder:759: Where is Pd API m_pd.h? Do 'make help' for info.
++++ info: making target all in lib helios
++++ info: evaluating implicit prerequisites in lib helios.....
src/helios.cpp:12:10: fatal error: 'm_pd.h' file not found
#include "m_pd.h"
^~~~~~~~
1 error generated.
src/pd-lib-builder/Makefile.pdlibbuilder:974: *** missing separator. Stop.

i also do not find the m_pd.h file in my finder (if thats even poissible)

i first do:
cd /Users/jakobschauer/Documents/Pd/externals/pd_helios-master
then:
PDINCLUDEDIR=../pure-data/src
right? 🤔

i also tried on another machine IOS 12.0.1. same same

Hey there,
i am also trying to get this lib working on an old ios 10.14.6.
https://github.com/timredfern/pd_helios
I followed all the steps described in the readme including "brew install libusb".
however i am getting an fatal error when I try to: make PDINCLUDEDIR=../pure-data/src/

my terminal says:
ls: ../pure-data/src//m_pd.h: No such file or directory
++++ info: using Makefile.pdlibbuilder version 0.5.1
src/pd-lib-builder/Makefile.pdlibbuilder:759: Where is Pd API m_pd.h? Do 'make help' for info.

#include "m_pd.h"
^~~~~~~~
1 error generated.
src/pd-lib-builder/Makefile.pdlibbuilder:974: *** missing separator. Stop.

it seams like there is a m_pd.h missing.
do you guys know what this error means? am i doing something wrong?

i downloaded the package and copied it to my /Documents/pd/externals folder. is that correct?
i am a max user and never really used pd + not to versed in using the terminal.

thanks
Jakob
