Errors compiling wmMatrix

[brydon10]

I've tried compiling the wmMatrix dockapp in Debian 13 and Linux Mint 22.2 and get the same "multiple definition" errors.

brydon@brydon-debian:~/dockapps/wmMatrix$ make
gcc -O2 -Wall -DLinux -c wmMatrix.c -o wmMatrix.o
gcc -O2 -Wall -DLinux -c matrix.c -o matrix.o
gcc -O2 -Wall -DLinux -c xutils.c -o xutils.o
gcc -O2 -Wall -DLinux -c yarandom.c -o yarandom.o
gcc -o wmMatrix wmMatrix.o matrix.o xutils.o yarandom.o -lXpm -lX11 -lXext

make: *** [Makefile:18: wmMatrix] Error 1

These are clean installs. I'm not sure what to do here.
