I can not get this to work, I am still trying to get comfortable with externals. Thankful for help, sorry for my ignorance. :/
pix_motion_sector (scroll down)
"Throw the pix_motion_sector folder in Pd's Contents/Resources/extra directory. The provided macintosh binary should work as-is. To build, cd to the pix_motion_sector directory and type "make". "
I put it first in Contents/Resources/extra and did build.
Something about installing xcode, I though I had it so I just went along.
Could not create [pix_motion_sector] in pd.
Tried to move the folder to my other externals user...documents/pd/externals. No luck.
Tried to remove and all files and rebuild.
make: Nothing to be done for `all'
Dowloaded Command_Line_Tools_for_Xcode_11.3.1 (I am on Mojave).
