python版本是3.7.2,之前编了python2版本的caffe一直在用,切换一下python3。
先贴一下makeconfig,不想看可以直接往下拉。

Q ?= @
可能会遇到如下问题:
CXX .build_release/src/caffe/proto/caffe.pb.cc
PROTOC (python) src/caffe/proto/caffe.proto
LD -o .build_release/lib/libcaffe.so.1.0.0-rc3
CXX/LD -o python/caffe/_caffe.so python/caffe/_caffe.cpp
/usr/bin/ld: cannot find -lboost_python3
collect2: error: ld returned 1 exit status
make: *** [python/caffe/_caffe.so] 错误 1
因为在配置文件的第 74 行中有 PYTHON_LIBRARIES := boost_python3 ,但是在系统中无法找到 boost_python3.lib 这个库文件。
解决方案如下:
检查是否有如下文件(末尾的数字可能根据版本有所不同):
ls /usr/lib/x86_64-linux-gnu/libboost_python-py35.so
如果有,说明我们的系统中已经有了这种库文件,只是文件名不同。
cd /usr/lib/x86_64-linux-gnu/
sudo ln -s libboost_python-py35.so libboost_python3.so
编译过程中报c++11的问题,在Makefile文件中加-std=c++11
# Linux
ifeq ($(LINUX), 1)
CXX ?= /usr/bin/g++
GCCVERSION := $(shell $(CXX) -dumpversion | cut -f1,2 -d.)
# older versions of gcc are too dumb to build boost with -Wuninitalized
ifeq ($(shell echo | awk '{exit $(GCCVERSION) < 4.6;}'), 1)
WARNINGS += -Wno-uninitialized
endif
# boost::thread is reasonably called boost_thread (compare OS X)
# We will also explicitly add stdc++ to the link target.
LIBRARIES += boost_thread stdc++
VERSIONFLAGS += -Wl,-soname,$(DYNAMIC_VERSIONED_NAME_SHORT) -Wl,-rpath,$(ORIGIN)/../lib
CXXFLAGS += -std=c++11//嗯就是这一行
endif
编译pycaffe的时候同样遇到c++11问题,同样在Makefile里加,这个难找一点
$(PY$(PROJECT)_SO): $(PY$(PROJECT)_SRC) $(PY$(PROJECT)_HXX) | $(DYNAMIC_NAME)
@ echo CXX/LD -o $@ $<
$(Q)$(CXX) -shared -o $@ $(PY$(PROJECT)_SRC) \
-std=c++11 \ //没错就是这一行
-o $@ $(LINKFLAGS) -l$(LIBRARY_NAME) $(PYTHON_LDFLAGS) \
-Wl,-rpath,$(ORIGIN)/../../build/lib
