Hello
I have a linking problem in the picoserver CAmkES-application which was added 2 days ago.
Steps I did:
1) repo init -u https://github.com/seL4/camkes-manifest.git 2) repo sync 3) start docker container 4) (in new subfolder) ../init-build.sh -DPLATFORM=x86_64 -DSIMULATION=1 -DCAMKES_APP=picoserver (side note: aborts because picotcp folder is missing in projects folder, but that's easy fixed) 5) ninja

I checked all the files in the Ethdriver component and for me it seems that all should be fine, thus I cannot find/see the error (or the missing configuration). (The only file I edited was picoserver.camkes but that is irrelevant.)
Any help/hint would be very appreciated.
Best regards,
