Makefile:15: recipe for target 'build/skbuff.o' failed

how to fix this error?
I just do make all on my Vbox with linux Ubuntu 18.04

install libcap-dev

same problem here, I got many errors,just like:

1. the comparison will always evaluate as ‘false’ for the address of ‘recv_wait’ will never be NULL
2. taking address of packed member of may result in an unaligned pointer value
3. ..

I solved these problems by doing this in the makefile:

1. remove -Werror
2. add -Wno-address-of-packed-member

You need to install libcap-dev:

sudo apt-get update
sudo apt-get install libcap-dev
