hi guys,
when trying to compile openssh-server openwrt for carambola2 , it fails with the following error:

Does anyone have any idea whats going on?

this error persists probably in the carambola2 packages.
In order to fix it temporarily ( though it works fine ) i copied the ./feeds/packages/net/openssh from a compilation of carambola1 to the same folder of carambola2 and recompiled carambola2. it works fine now
