Nerei@60e8f7a#commitcomment-9141630 According to this @longjon 's comment, I reverted last commit where I had reduced NumPy requirements from 1.7.1. to 1.6.1. But now python interface compilation is not tested by Travis CI. Need to update numpy there.

Re: numpy versions, Travis should use a recent version after #1473. (If we want to build pycaffe with these CMake updates before that, the Travis build script could be modified to force CMake to go ahead with an older version, either by some CMake switch that I don't know, or by actually updating the CMake script before the build.)

I noticed that some tasty python features are being implemented (Once they're done, I'm ready to prepare new PR with its support)

@Nerei thanks for the effort to improve the CMake build and align it with the features of the Makefile. Nice to have the pieces in place to include Caffe in other projects too.

Regarding the shared or static library build, I'd rather the shared library be the default since it is used more commonly (right?).

👍 for shared default

Absolutely agree that shared is better! Just it was for similarity with previous vesion.

@Nerei I'm guessing what is the support status for windows generators with this refactoring. Working VS generators could help people at #15

Great work @Nerei! Is this ready for review or are there further changes planned for this PR?

(Of course more can be done in follow ups, such as CMake support for the new Python features that are on track for merge.)

To: @bhack CC: @shelhamer @Yangqing

Absolutely, agree that can use windows generators with cmake. But now I don't think that windows is currently supported by caffe without modifications.

If you compile caffe as dynamic library, Attribute __declspec(dllexport) using macro like here should be added to the beginning of EACH class and function in caffe, otherwise the symbols won't be visible from outside of dll-library. In case of static compilation, current layer registration scheme (introduced in @Yangqing's commit 2f88dab) doesn't work because unreferenced static constructors that register layers are just excluded by linker. To fix this, caffe uses workaround in Makefile.

For Windows, one may try -DCMAKE_CXX_FLAGS=/OPT:NOREF option, But I'd rather rewrite the code since anyway it is not very cross-platform, produces difficulties with different compilers, with Matlab/Octave interface and even with clang for ubuntu (--force-load only for shared libraries not for executables). Even if I make it work for some set of compilers now, it would be difficult to support and test these scripts in future for different configurations.

@shelhamer Thanks! I think it's ready for review. At least future changes, like windows support or improvements, I would cover in separate PR.

I think better to fetch the branch and review cmake-files locally, it should be easy to read. I wanted to write them as very readable, all difficulties are separated as macros, most of which I just copy-pasted from my projects and opencv. My aim was to create some well done basis/style and standardize it, so that it would be clear where/how to write changes in future.

Regarding windows, I might be worth creating a repository with cmakeified dependencies so that one can compile and use use the dependencies for caffe compilation "in couple clicks". I can help with this since I am primary a windows user.

@Nerei I'm not a window user but in past for other projects we have used MXE on Linux to cross compile dependencies. It integrates also well with Cmake.

@bhack Interesting. But cmake scripts are required to be written anyway. And this cross-compile tool uses mingw (gcc port to windows), and its output can't be used from Visual Studio, only from mingw.

@Nerei VS generators are a feature of cmake. FindScripts need to be written or copied by other BSD project for correct multiplatform support (ones that are not already distributed by Cmake). Mxe is only for building easly I.e. widows dependencies from Linux or easily compiling caffe for windows target in Linux with almost the actual infrastructure.

Yes. you're completely right, you can compile caffe.exe from linux for windows and use the executable. there. But not cafe.lib to link into your Visual Studio application. The same with dependencies.

Static library are directly supported in VS. Also dynamic ones are supported with some additional steps

Please ask on caffe forums. Actually you should set Caffe_DIR to caffe build directory, not source one.

Hi all,

I have installed caffe and have tested with a mnist script. That one is working, also with the gpu :)

Now, I am trying to work with the matlab interface. I am testing with the basic demo from CAFFE_FOLDER/matlab/demo

However, I am getting the error:

[libprotobuf FATAL google/protobuf/stubs/common.cc:61] This program requires version 3.0.0 of the Protocol Buffer runtime library, but the installed version is 2.5.0. Please update your library. If you compiled the program yourself, make sure that your headers are from the same version of Protocol Buffers as your link-time library. (Version verification failed in "google/protobuf/any.pb.cc".)

I have verified that I have the proto version 3.00 in my path with 'protoc --version' in console and also in matlab with unix('protoc --version') and I am getting version 3.00. However, still has the previous error.

Any suggestions ?

Thanks.

I am continuously getting this error while trying to install Caffe using CMake:
/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/libglog.so: undefined reference to `google::FlagRegisterer::FlagRegisterer(char const_, char const_, char const_, char const_, void_, void_)'

Please help!

Hello,

I am trying to use Caffe API in my project in visual studio but I have the same issue as @InfiniteLifeH has, @Nerei I set Caffe_DIR to build and still have the problem. I am getting this warning in Cmake :

CMake Warning at (find_package):
By not providing "FindCaffe.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Caffe", but
CMake did not find one.

Could not find a package configuration file provided by "Caffe" with any of
the following names:

CaffeConfig.cmake
caffe-config.cmake

Add the installation prefix of "Caffe" to CMAKE_PREFIX_PATH or set
"Caffe_DIR" to a directory containing one of the above files. If "Caffe"
provides a separate development package or SDK, be sure it has been
installed.
Any suggestions?

Thanks,

I have solved this problem. I tried to edit CMakeCache.txt in the build file and changed

//Path to a library.
Atlas_CBLAS_LIBRARY:FILEPATH=<path to libcblas.a>

into

//Path to a library.
Atlas_CBLAS_LIBRARY:FILEPATH=/usr/lib/libcblas.so //<path to libcblas.so in my machine>

and it works.
i suppose it is because i have tried to install atlas things to many times LOL
thanks a lot @flowirin

@riteshpradh
hi,I met the same question as yours,could you share the solution?thanks a lot.
my email is 714789880@qq.com

@longjon
hi,there is a question I met:
make symlink
make: *** No rule to make targetsymlink'. Stop.`
I am lack of experience on the CMake and Linux ,could you tell me what shoud I do ?
Thanks a lot.

Hi, I have error like this:

CMake Error at CMakeLists.txt:83 (add_dependencies):
  The dependency target "pycaffe" of target "pytest" does not exist.

I can still do next steps to finish compiling. What should I do to solve this error?
Hoping to get help, thanks a lot! ^_^

Who can tell me how to use intel mkl to compile caffe with cmake????

@viscropst In case you are still wondering, to build w/ Intel MLK, you can do the following:
cmake -DBLAS=MLK ..
I haven't tried MLK specifically, but BLAS=Open works for me (for OpenBLAS). Take a look at the file cmake/Dependencies.cmake.

Compilation crushed on the following errors. Can anyone help?
