Hi, I am trying to compile openconnect version 7.06 on my Synology NAS DS 212+ This works fine up to version 7.04 but if I try to compile 7.06 I always end up with the following error: ============================================================= ./.libs/libopenconnect.so: undefined reference to `esp_shutdown' collect2: ld returned 1 exit status ============================================================= I could not find anything in the mail archive nor on the internet about this particualt error and what could be wrong here. Any kind of help would be great. Regards Klaus
