This is a script to compile caffe without root permission. It hasn't been extensively tested, but it will hopefully still make things easier than going about it on your own. Please let me know if there are any bugs!

install_caffe.sh

# This script installs (or at least, attempts to install) Caffe in CPU mode
# with Python bindings without root permission. In doing so, it installs the
# following dependencies:
#
# * protobuf
# * cmake
# * gflags
# * glog
# * opencv
# * hdf5
# * python2
# * pip
# * libpng (recent version required for freetype)
# * automake (recent version required for freetype)
# * freetype (required for scikit-image)
# * various python modules
#     - numpy
#     - scipy
#     - scikit-image
#     - protobuf
#     - yaml
# * boost
# * lmdb
# * libtool
# * snappy
# * leveldb
# * openblas

should have no space after -L before path. All the rest look correct.

There is a problem with cmake installation,

When installing gflags, it gives an error cmake command not found (line 129). Please can you look into the matter.

Error at line 374
Correct:
install_protobufs

---

Error at line 112 and 113.
Line should be swaped.
Correct:
untar_to_dir "cmake-3.2.3-Linux-x86_64.tar.gz"
cd ${LOCAL_INSTALL_DIR}

Thank you!
