OK,
I have downloaded the iemlib from Deken.
The iemlib from Deken (iemlib[v1.22] (Linux-armv7-32).dek is in one single folder called "iemlib". The file "iemlib.pd_linux" is inside of the folder.
I have tried these options:
[declare -lib iemlib] [declare -lib iemlib -path iemlib] [declare -lib iemlib -path /usr/lib/puredata/extra/iemlib]
[declare -path iemlib] [declare -path /usr/lib/puredata/extra/iemlib]
Both! Declare -path AND -lib as many others have shown before! [declare -path /usr/lib/puredata/extra/iemlib -lib iemlib]
Turn on "verbose Messages" in Pd's preferences to see if/where Pd is looking for iemlib.pd_linux.
You are almost there, we halten our Daumen gedrückt!
