Caffe-segnet：重新定义参数'compiler-bindir'

Question

[尝试编译caffe-segnet已经好几天了，现在停留在此错误上，我正在使用gcc gcc (Ubuntu 4.8.5-4ubuntu8) 4.8.5 来编译caffe-segnet。我正在使用caffe和opencv文档中提到的Cuda 9.0，cudnn v2和opencv 3.3.0。如cudnn所述，是否在Makefile.config中禁用here不会更改任何内容。

在我使用cuda 10.0和cudnn 7.0并删除所有内容之前，因为在启动模型时出现了很多错误。这是使用make all时的输出错误：

以及错误来自Makefile的第544行：

...
    @ 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)
...

注意，我尝试使用gcc 5和gcc 7进行编译，并且会出现相同的错误！有什么主意吗？

编辑1：我也将此CUSTOM_CXX := /usr/bin/g++-4.8添加到了Makefile.config

Answer 1

由于没有人问我最终还是找到了解决方案，因此导致此错误是因为两次调用相同的参数，因此在Makefile中添加了以下代码行：

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

为避免此错误/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.

在同一文件中在完整的构建标志中]，我们具有相同的标志：

...
# 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
...
我所做的是评论我添加的标志：

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
并将-std=c++11参数添加到完整构建标志

部分的NVCCFLAGS中，结果变成了这样：

...
# 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
...
在编辑Makefile之后执行make all之前，请确保执行make clean，否则会收到相同的错误！
