Compile error 0.11.6

[Edmond Chu]

Hi,

I found an error to compile the version 0.11.6 which is no problem on
compiling 0.11.5

  AR       libopts.a
make[3]: Leaving directory `/root/ocserv-0.11.6/libopts'
make[2]: Leaving directory `/root/ocserv-0.11.6/libopts'

                rm -f ./ocserv-args.c; \
                rm -f ./ocserv-args.h; \
                cp ./autogen/ocserv-args.c ./; \
                cp ./autogen/ocserv-args.h ./; \
        else \
                : ocserv-args.def; \
                if test -d ./autogen;then \
                        cp ./ocserv-args.c ./autogen; \
                        cp ./ocserv-args.h ./autogen; \
                fi; \
        fi

I am using CentOS 6.5, it should be no libopts things on previously ??
and autogen things also.

how can I fix it??
