The problem is due to an optimization of the dtls library which I use for arm platforms.
I have to adjust the compiler options.
Which hardware platform and OS do you use?

see here

I am using Armbian(Xenial) on a Orange PI One

please try:
login to shell and install manually

export CFLAGS='-fomit-frame-pointer'
cd /path-to-pimatic/node_modules
git clone https://github.com/treban/pimatic-tradfri.git
cd pimatic-tradfri
npm install

The workaround above worked. I have installed the plugin correctly. This evening I will try to configure and connect to the Tradfri gateway. Thanks!!!

Nice to hear. I will find a general solution. This requires changes to the library package. I would come back to you again to test the result.

HI @bkrijg,
i will publish a new library version soon, so this error should be fixed.
Can you run a test afterwards, please?

[bkrijg]

Hi, I will run the test afterwards.
