file software_C.obj specifies ISA revision "C2800" which is not compatible with ISA revision "C28FPU32" specified in previous file or command

I have looked through many of the existing posts concerning this error and I find myself in a whirl as the error will not go away. 

I understand what the error says but when I take away the FPU support from my project in code composer, I get this issue:

Severity and Description Path Resource Location Creation Time Id
file "C:/vissim90/cg/lib/ii_F280X_fpu.lib<rtF2812.obj>" specifies ISA revision "C28FPU32", which is not compatible with ISA revision "C2800" specified in a previous file or on the command line Challenger line 0 1431107326776 1433

My project does use FPU hardware and that is why I am using that library. The issue seems to revolve around my .obj file. Any suggestions please? I am stumped at this point. Thanks.

    The original error in your subject line indicates something in your project (software_c.c seems likely) has been built without the --float_support=FPU32 compiler switch.

    Maybe the file specific options have somehow been set - right click on the file in the project view and go down to properties. Check if the file specific options have it turned off.
