Caffe Compile Error

[Jacky Wang]

Hi all, 

I have followed http://caffe.berkeleyvision.org/installation.html#compilation to use the cmake copmilation. 

I was successful in the "cmake .." step from my build folder. However, when I do "make all" inside the build folder. I reached around 85% completion and the compiler erred out with the following message. I'm on Max OSX 10.9.5 (Mavericks).

ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

make[2]: *** [lib/libcaffe.dylib] Error 1

make[1]: *** [src/caffe/CMakeFiles/caffe.dir/all] Error 2

make: *** [all] Error 2

Not sure if people have seen such error before and how they went about solving it. Any suggestion is greatly appreciated. Thank you in advance!

My advise is to use Cuda 7.0 and re-install all dependencies without the "-stdlib=libstdc++" step

Thank you Anatoly. I will try that and share the results with others here.

Hi, 

After installing CUDA 7, it did get rid of the previous linking errors that I have. Again, I'm on Mac OSX10.9.5.

However, I'm seeing new errors:

Linking CXX executable caffe

Undefined symbols for architecture x86_64:

  "google::SetUsageMessage(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&)", referenced from:

      _main in caffe.cpp.o

ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

make[2]: *** [tools/caffe] Error 1

make[1]: *** [tools/CMakeFiles/caffe.bin.dir/all] Error 2

make: *** [all] Error 2

Not sure if anyone can shed some light. Thank you in advance.

It finally finished make all without errors at the end.

I forgot to remove the formula edits that I have done previously when I had CUDA 6.5 (which is described here http://caffe.berkeleyvision.org/install_osx.html  under libstcd++ installation section).

However, upon make runtest, I eventually get

Not sure if it's still a compilation problem? 

I would really appreciate any comments. Thank you in advance!

After brew uninstalling a few formulas, boost snappy leveldb protobuf gflags glog szip lmdb, and brew installing them again.

My "make runtest" completed. However, it has this final message:

"YOU HAVE 2 DISABLED TESTS"

Not sure if that's a default behavior for others. Hopefully those tests aren't critical.

[Evan Shelhamer]

"YOU HAVE 2 DISABLED TESTS"

This is fine -- there are two tests for a math function that was not yet implemented so the test are disabled. At this point we'll likely just strip them out.
