I am getting multiple definition errors when linking for loads of functions, and im pretty sure it is due to my makefile. I cannot post much of the project, as it is pretty large, but the makefile is below, does anything stand out as obviously wrong? I had multiple definition of some functions declared + defined in a header, and moving their definitions into a cpp removed those functions from the linker errors - but I cannot do this for all of them (EDIT: The rest of the functions that are being multiply defined are not in headers, they are in cpp/cc files as standard, saying "i cannot do this for all of them" implied they were all like that, sorry), as a large portion is a codebase I cannot edit. There shouldnt be any errors in the code though as it is building fine in a separate project without my additions (none of which are causing linker errors), so I figure it must be my makefile, but I cant figure out what I am doing wrong. Any Ideas? # Compiler CXX = g++ # Linker settings LDFLAGS = -lGL -lGLU -lXext -lX11 # Executable name EXEC = SplotchPreviewer # Optimizations for compilation OPTIMIZE = -std=c++98 -pedantic -Wno-long-long -Wfatal-errors -Wextra -Wall -Wstrict-aliasing=2 -Wundef -Wshadow -Wwrite-strings -Wredundant-decls -Woverloaded-virtual -Wcast-qual -Wcast-align -Wpointer-arith -O2 -g # Pre-processor settings CPPFLAGS = $(OPTIMIZE) -I. -Icxxsupport -Ic_utils # Default Splotch objects OBJS_SPLOTCH_DEFAULT = cxxsupport/error_handling.o reader/mesh_reader.o cxxsupport/mpi_support.o cxxsupport/paramfile.o \ cxxsupport/string_utils.o cxxsupport/announce.o reader/gadget_reader.o reader/millenium_reader.o \ reader/bin_reader.o reader/tipsy_reader.o splotch/splotchutils.o splotch/scenemaker.o \ cxxsupport/walltimer.o c_utils/walltime_c.o booster/mesh_creator.o booster/randomizer.o \ booster/p_selector.o booster/m_rotation.o cxx
