I'm getting this compilation error

You likely don’t need those tools, they are KLIPS only, not used for the native Linux IPsec stack. Try compiling without klips support enabled (with libreswan that’s USE_KLIPS=false) Sent from mobile device

I have suppressed the error by making just a warning, by passing -Wno-stringop-truncation to GCC.
