I am having trouble to try profile my code using the simple -gf profiler. I find that I am unable to actually compile my code with the switch in. I have been use to use the profile for a very simple piece of code (i.e. one file). I think the problems relates to the way I am including files and my make files for example. this is my make file: all: Sim Sim: FileHandling/FileHandling.o FileHandling/StructureFile.o Initialize/Initialize.o MC/MC.o Random/Random.o Rotation/Rotation.o Display/Display.o Stress/TBstress.o Vectors/Vectors.o CellIndex/Cell.o Energy/Energy.o Clash/Clash.o Main.o g++ -O3 -o Sim FileHandling/FileHandling.o FileHandling/StructureFile.o Initialize/Initialize.o MC/MC.o Random/Random.o Rotation/Rotation.o Display/Display.o Stress/TBstress.o Vectors/Vectors.o CellIndex/Cell.o Energy/Energy.o Clash/Clash.o Main.o Vectors/Vectors.o: Vectors/Vectors.cpp g++ -O3 -c -Wno-deprecated -g -Wall Vectors/Vectors.cpp -o Vectors/Vectors.o ------------------------------ The makefile works fine with the -pg switch. However upon insertion into the linking part complains with a myriad of errors which are complaints that functions have already been declared. I never get these errors when I normally compile. In each of my files I include normally all other files and wonder if there is an easy way to solve the problem without messing around to see what files go where? i.e. in my Mainfile I have #include "Variables/Variables.h" #include "Clash/Clash.h" #include "Energy/Energy.h" #include "FileHandling/StructureFile.h" #include "FileHandling/FileHandling.h" #include "Initialize/Initialize.h" #include "Random/Random.h" #include "Rotation/Rotation.h" #include "CellIndex/Cell.h" #include "MC/MC.h" #include "Display/Display.h" #include "Stress/TBstress.h" I have tried compiling as a single line....and find I get similar errors. Ideally I would like to keep my Makefile structure rather than move to a single line. Can anyone suggest what to do?
