Installation on Ubuntu 16.04

[Piotr Mitros]

Hello,

I just install caffe on Ubuntu 16.04. There were some steps beyond what was described in the instructions, and I thought I'd post here in case it was helpful for others. This was the set of additional apt packages needed: 

  libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler

  libboost-all-dev libatlas-base-dev libopenblas-dev libgflags-dev libhdf5-dev liblmdb-dev

Looking at my logs, I also installed libgoogle-glog-dev from Ubuntu 16.10 in the process, but I think that was for an additional package on top of caffe, and not caffe itself. 

In addition, in Makefile.config, I needed to change:

< CPU_ONLY := 1

---

> # CPU_ONLY := 1

94,95c94,95

< INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial/

< LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu/hdf5/serial

---

> INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include
> LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib

Obviously, many people will not want to change CPU_ONLY. I'm also not sure whether I needed to add both additional library directories. I added the first. It didn't work. I added the second. It did. Both had what looked like files relevant to errors I saw. 

In addition, I needed to include the library dependencies for OpenCV in the Makefile itself (error was: "undefined reference to cv::imread(std::string const&, int)" and solution was found at https://stackoverflow.com/questions/25476466/error-undefined-reference-to-cvimreadstdstring-const-int)

< LIBRARIES += opencv_core opencv_highgui opencv_imgproc opencv_shape opencv_stitching opencv_objdetect opencv_superres opencv_videostab opencv_calib3d opencv_features2d opencv_highgui opencv_videoio opencv_imgcodecs opencv_video opencv_photo opencv_ml opencv_imgproc opencv_flann opencv_viz opencv_core opencv_hal

---

> LIBRARIES += opencv_core opencv_highgui opencv_imgproc

I'm not using caffe itself, but a package which depends on it (at least for the next day or two; I may need to dive deeper depending on what performance I see), so I have not done a complete test of whether things work beyond the caffe command not crashing on the command line and the tool I am using working. 

This post is purely intended to be informational for future developers so they might have a complete list of changes needed to make caffe build. No response required.

Hi Piotr,

I noticed a lot of what did also, although the opencv changes didn't seem to be required. The following is my Makefile.config for 16.04:
https://gist.github.com/williford/aa13f6bc4b676e9cb75d71b3e76cde13

The Ubuntu 14.04 dependencies are also dependencies for 16.04, I (or someone else) should really submit a PR to update that. If you include those dependencies, I think all the dependencies you listed are covered.

Cheers,

Jonathan
