Having trouble compiling

[MichaelHinrichs]

im trying to compile in codeblocks, and every line in Matrix44.cpp that begins with Matrix44 causes the error "'Matrix44' does not name a type". Every line that begins In Matrix44 with something like bool of void in front of it causes the error "expected initializer before '<' token. I tried including Matrix44.h, but that just makes it say "error: redefinition of" whatever the line with Matrix44 in it says.
