Error trying to build file for Khepera 4 mobile robot

I am trying to set up Eclipse for development with the Khepera 4 mobile robot and I'm running into errors when trying to build my test file. Specifically the error gcc: error: unrecognized command line option ‘-mfloat-abi=hard’ I've been following the manual (https://ftp.k-team.com/KheperaIV/software/Gumstix%20COM%20Y/UserManual/Khepera%20IV%20User%20Manual%204.x.pdf) and I'm unsure where the issue is.
