I tried to compile the sane-backends from source but getting the following messages after running make, to configure, I ran ./configure --enable-avahi BACKENDS='canon genesys test'

make[1]: Leaving directory /home/.../sane-backends/po'
Making all in testsuite
make[1]: Entering directory/home/.../sane-backends/testsuite' Making all in sanei make[2]: Entering directory /home/.../sane-backends/testsuite/sanei'
run 'make check' to run tests

Use 'make check' to run the tests.
run 'make check' to run tests

What's wrong with for all-am?

  • Which part(s) do you consider error messages? I don't see any. – David Foerster Feb 28 '16 at 9:43
  • why it saying 'Nothing to be done for all-am'??? – Pavel Sayekat Feb 28 '16 at 9:47
  • Ok, I see what you mean… – David Foerster Feb 28 '16 at 14:43

You seem to be mistaken as to what is considered an error condition of the make program. "Nothing to be done" is not an error; it means that there is nothing left to do because the job was already done at a previous invocation of make. You can also look at the exit status of the make invocation if you run echo $? just afterwards. "0" means "no error encountered, everything was done as you asked".

Occasionally "Nothing to be done" is caused by a faulty Makefile (a. k. a. "job description") that doesn't reflect the intended action. You should report this as a bug to the author(s)/maintainer(s) of the Makefile.
