出现该问题有两种情况,可以先尝试下面的链接:https://github.com/BVLC/caffe/issues/1358 如果不行,那说明是 Makefile
文件除了问题。一般来说,按照 https://github.com/BVLC/caffe/pull/1740里的 33a56e0
那个 post 来修改 Makefile
文件就解决了。 在出错之前,Makefile
相关内容如下:
ifeq ($(OSX), 1)
CXX := /usr/bin/clang++
CXXFLAGS += -stdlib=libstdc++
LINKFLAGS += -stdlib=libstdc++
# clang throws this warning for cuda headers
WARNINGS += -Wno-unneeded-internal-declaration
ifneq ($(findstring 10.10, $(shell sw_vers -productVersion)),)
CXXFLAGS += -stdlib=libc++
LINKFLAGS += -stdlib=libc++
endif
# gtest needs to use its own tuple to not conflict with clang
CXXFLAGS += -DGTEST_USE_OWN_TR1_TUPLE=1
# boost::thread is called boost_thread-mt to mark multithreading on OS X
LIBRARIES += boost_thread-mt
NVCCFLAGS += -DOSX
然后修改成 33a56e0
的样子就成功了。
解决方法 https://github.com/BVLC/caffe/issues/1212
解决方法 存在上一次安装的残留文件。用 make clean
清除之前的安装,重新编译即可
解决方法:adna 没有安装 hdf5
。重新安装 hdf5

解决办法:出处忘记了... @reking, I see boost errors, which I vaguely recall getting myself. If I recall, Caffe was seeing Matlab's internal libraries earlier in the library path than my local homebrew libraries in /usr/local/lib. Caffe might be trying to link Matlab's version of the boost library, which, needless to say, isn't compatible with Caffe.
Try changing the LIBRARY_DIRS := ... line in your Makefile.config so that the /usr/local/lib
directory is before your Matlab library directory.
Mine looks like this:
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib $(MATLAB_DIR)/bin/maci64 /usr/lib

解决办法: 9) 的错误和 8)很相似。但是我注意到错误提示: clang++ .build_release/src/caffe/proto/caffe.pb.cc -stdlib=libstdc++ -DGTEST_USE_OWN_TR1_TUPLE=1
有这么一行。在这一行里,有 -stdlib=libstdc++
字段。如果其他依赖库用 libc++ 编译的话,那么就会出现 9)的错误。解决办法是在 Makefile 文件里,将带有 libstdc++ 的行注释掉即可。
2015.7.2 补充。今天在编译老版本 caffe-rc2
版本的时候,又出现了一次该错误。但当时我是把最新版本的 makefile.config
文件给复制过来用了,并没有重新填写。所以,考虑到这个情况。我又重新解压了一次 caffe-rc2.zip 压缩包,重新手动填写了一次 makefile.config
文件。再次编译就好了。
出现这种错误的原因解释在下面链接的 OSX 一节:http://kyamagu.github.io/mexopencv/ 解决方法上面链接也给了。但是下面的链接讨论的更为详细:https://github.com/kyamagu/mexopencv/issues/71
我自己的解决办法是,在 terminal
里输入DYLD_INSERT_LIBRARIES=/usr/local/lib/libopencv_highgui.2.4.dylib:/usr/local/lib/libtiff.5.dylib /Applications/MATLAB_R2014b.app/bin/matlab
因为,matlab
运行 RCNN
代码时提示 libopencv_highgui.2.4.dylib
使用的是 Matlab
自己的。所以就在终端里插入系统库。 而libopencv_highgui.2.4.dylib
系统库又要调用 libtiff.5.dylib
, 所以再继续插入libtiff.5.dylib
。
在编译 caffe
中的最后一步,运行 make runtest
时,出现了 caffe
无法找到libopenblas.so.0
的错误。出现这个错误的原因是,从源码编译 openblas
时手动更改了安装路径。 解决方法是,建立一个软连接到 openblas
的默认安装路径即可。 cd /opt sudo ln -s /usr/local/OpenBLAS/ .
然后将 openblas
的库所在位置添加到系统环境变量 LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/opt/OpenBLAS/lib/ sudo ldconfig
这时,在编译就不会出错了。

Invalid MEX-file '/home/coldmoon/ComputerVision/Caffe/matlab/caffe/caffe.mexa64':
/home/coldmoon/MATLAB/R2014b/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.20'
not found (required by /home/coldmoon/ComputerVision/Caffe/matlab/caffe/caffe.mexa64)
参考 http://askubuntu.com/questions/575505/glibcxx-3-4-20-not-found-how-to-fix-this-error http://stackoverflow.com/questions/16605623/where-can-i-get-a-copy-of-the-file-libstdc-so-6-0-15
上面两个链接指出的是,在 libstdc++.so.6
中无法找到 GLIBCXX_3.4.20
时的解决办法。但在我系统里 OSX(10.10),情况跟上述不一样。 通过下列命令 find / -name "libstdc++.so.6"
可以找到官方提供的库所在路径。 然后进入该路径: strings ./libstdc++.so.6 | grep GLIBCXX
可以看到,官方提供的 libstdc++.so.6
已经包含了 GLIBCXX_3.4.20
。这说明 caffe.mexa64
所使用的库并非官方的库,而是 matlab
自己提供的库 根据https://github.com/rbgirshick/rcnn/issues/13 的说法,这是LD_LIBRARY_PATH
设置不当造成的。导致了程序优先寻找 matlab
目录下的 libstdc++.so.6
。至于 matlab
究竟引用了哪里的库,可以通过 ldd
命令查看。 根据 https://github.com/rbgirshick/rcnn/issues/9 在终端下,输入ldd caffe.mexa64
,可以看到一堆所引用的库路径。而在 matlab
的命令窗口中输入 !ldd caffe.mexa64
则可以看到 matlab
运行 caffe
函数时,究竟在引用哪些库。不出意外的发现,matlab
引用的库路径果真都是 matlab
自己的。因为其中列出一条: libstdc++.so.6 => /home/coldmoon/MATLAB/R2014b/sys/os/glnxa64/libstdc++.so.6 (0x00007f2664bb6000)
再次运行 strings ./libstdc++.so.6 | grep GLIBCXX
,就可以发现,果真没有 GLIBCXX_3.4.20
.
解决方法,参考 https://github.com/BVLC/caffe/issues/655https://github.com/kyamagu/mexopencv/issues/64https://github.com/kyamagu/mexopencv/issues/62#issuecomment-15054244
当我把所有 !ldd caffe.mexa64
输出的结果都放到 LD_PRELOAD
中是,!ldd
这个命令会出错,即使不给它参数也会出错。因此, 我只把libstdc++
放到了这个环境变量里。最终形成一个脚本文件来运行 matlab
:
#!/bin/bash
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6
echo "LDPRELOAD is:"
echo $LD_PRELOAD
