that there is no Makefile but Makefile is present. tell me what is the
problem? Please

Because do_compile runs from ${S} which by default is set to ${WORKDIR}/${PN}-${PV} (might be BPN instead of PN but does not matter). Basically it expects to be run from ${WORKDIR}/gobinet-1/.

However the content of the tar.xz is extracted directly within ${WORKDIR}. So it's looking for a Makefile in ${WORKDIR}/gobinet-1/ but it's in ${WORKDIR}.

Two possible ways to do it:
1. Set S to ${WORKDIR}
2. Put all your files in a directory named gobinet-1 and make a tarball of that directory.

Cheers,
Quentin
