I am trying to compile on MacBook Pro Retina with CUDA Driver Version: 7.0.36 and cuda toolkit 7.0 in a nVidia GT 750 M, the following code with its makefile but it gives me this error:
nvcc fatal : redefinition of argument 'optimize'.
Despite I have been able to compile and execute other programes with nvcc, with makefiles and so, now I am not.
Also, I have not been able to find something useful about this error so I ask it here if someone knows how to solve it. I am new with CUDA so if you need more information please ask for it.
Here is my Makefile.inc
:
CXX := nvcc
OPTIM := -O3
DEBUG := -g -DOLB_DEBUG
CXXFLAGS := $(OPTIM)
ARPRG := ar
LDFLAGS := -O3
PARALLEL_MODE := OFF
OMPFLAGS := -fopenmp
BUILDTYPE := precompiled
INPUTDIR := ./input
OUTPUTDIR := ./output
INCDIR := ./inc
OBJDIR := ./obj
SRCDIR := ./HeatTransfer
BINDIR := ./bin

The complete messege when I try to compile is this:
...Heat_Transfer_CUDA$ make
Compile HeatTransfer/mesh.cu
nvcc -O3 -I./inc -c HeatTransfer/mesh.cu -o obj/mesh.o
Compile HeatTransfer/stack.cu
nvcc -O3 -I./inc -c HeatTransfer/stack.cu -o obj/stack.o
Link bin/program
nvcc -O3 -I./inc ./obj/mesh.o ./obj/stack.o -O3 -I./inc -o bin/program
nvcc fatal : redefinition of argument 'optimize'
make: *** [bin/program] Error 1
The problem is arising due to the fact that your link command is specifying the -O3
switch twice:
nvcc -O3 -I./inc ./obj/mesh.o ./obj/stack.o -O3 -I./inc -o bin/program
^^^ ^^^
And this is not allowed - it will produce that error.
The problem seems to occur due to the fact that your makefile
specifies the use of LDFLAGS
twice here:
$(CXX) $(LDFLAGS) -I$(INCDIR) $(foreach file, $(HeatTransfer), $(OBJDIR)/$(file).o) $(LDFLAGS) -I$(INCDIR) -o $@
which should not be necessary. Something like this instead:
$(CXX) $(LDFLAGS) -I$(INCDIR) $(foreach file, $(HeatTransfer), $(OBJDIR)/$(file).o) -o $@
should probably fix the issue.
