odd linker error occuring when making program: 'multiple definition of `fnames'; src/main.o:(.data.rel.local+0x0): first defined here'

So I am programming a program that grew so much that I decided to create many files for this project (as I have done before). After creating 2 files and putting the appropriate functions in them these are the errors I get when make-ing.

/bin/ld: src/util.o:(.data.rel.local+0x0): multiple definition of `fnames'; src/main.o:(.data.rel.local+0x0): first defined here/bin/ld: src/util.o:(.data+0x0): multiple definition of `gBoard'; src/main.o:(.data+0x0): first defined here/bin/ld: src/possiblemoves.o:(.data.rel.local+0x0): multiple definition of `fnames'; src/main.o:(.data.rel.local+0x0): first defined here/bin/ld: src/possiblemoves.o:(.data+0x0): multiple definition of `gBoard'; src/main.o:(.data+0x0): first defined herecollect2: error: ld returned 1 exit statusmake: *** [Makefile:22: vgcp] Error 1

Here is my Makefile:
