Problem:
You are trying to clean your SCons build using
scons clean
but you see the following error message:
scons: Reading SConscript files ... scons: done reading SConscript files. scons: Building targets ... scons: *** Do not know how to make File target `clean' (/home/user/myproject/clean). Stop. scons: building terminated because of errors.
Solution:
When using SCons, the correct command to clean is
scons --clean
