Libsearpc build error

Hi all,

I tried to build seafile server using the following link:
https://seafile.gitbook.io/seafile-server-manual/developing/how-to-build-seafile/server

But i got a error when i try to build “libsearpc” and the error is:

config.status: error: cannot find input file: `lib/Makefile.in’

Can someone help me to pass through this error?
