Caffe-segnet: redefinition of argument 'compiler-bindir' - makefile

Question

It's been days trying to compile caffe-segnet, and now stuck at this error, I m using gcc gcc (Ubuntu 4.8.5-4ubuntu8) 4.8.5
to compile caffe-segnet. I'm using Cuda 9.0, cudnn v2 and opencv 3.3.0 as mentionned in the documentation of caffe and opencv. Disabling cudnn or not in the Makefile.config doesn't change anything as mentioned here.
Before that I was using cuda 10.0 and cudnn 7.0 and deleted all because when starting my model there was so many errors. Here is the output error when using make all:

and the line 544 in Makefile which the error come from:
...
# cat $#.$(WARNS_EXT)
$(BUILD_DIR)/cuda/%.o: %.cu | $(ALL_BUILD_DIRS)
544> # echo NVCC $<
$(Q)$(CUDA_DIR)/bin/nvcc $(NVCCFLAGS) $(CUDA_ARCH) -M $< -o ${#:.o=.d} \
-odir $(#D)
...
Notice that I tried compiling it with gcc 5 and gcc 7 and the same error occur ! Any idea guys ?
EDIT 1:
I also added this CUSTOM_CXX := /usr/bin/g++-4.8 to Makefile.config

Answer 1

Since no one aswered I finaly found a solution, the error is caused because the same argument is called twice, in my Makefile I added those lines of code:
CXXFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS) -std=c++11
NVCCFLAGS += -D_FORCE_INLINES -ccbin=$(CXX) -Xcompiler -fPIC $(COMMON_FLAGS) -std=c++11
LINKFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS) -std=c++11
to avoid this error /usr/include/c++/4.8/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options.
In the same file in the complete build flags, we have the same flag:
...
# Complete build flags.
COMMON_FLAGS += $(foreach includedir,$(INCLUDE_DIRS),-I$(includedir))
CXXFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS)
NVCCFLAGS += -ccbin=$(CXX) -Xcompiler -fPIC $(COMMON_FLAGS)
# mex may invoke an older gcc that is too liberal with -Wuninitalized
...
what I did is commenting my flag I added:
CXXFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS) -std=c++11
#NVCCFLAGS += -D_FORCE_INLINES -ccbin=$(CXX) -Xcompiler -fPIC $(COMMON_FLAGS) -std=c++11
LINKFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS) -std=c++11
and add -std=c++11 argument to NVCCFLAGS in the complete build flags section, it turned to be something like this:
...
# Complete build flags.
COMMON_FLAGS += $(foreach includedir,$(INCLUDE_DIRS),-I$(includedir))
CXXFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS)
NVCCFLAGS += -ccbin=$(CXX) -Xcompiler -fPIC $(COMMON_FLAGS) -std=c++11
# mex may invoke an older gcc that is too liberal with -Wuninitalized
...
Before doing a make all after editing your Makefile, make sure you do a make clean or you'll get the same error !
