install_linux_no_root.txt

This file contains notes on how to install all of the required libraries on
Linux to your local user directory if you don't have root access.


Required libraries:
  - cmake 3+
  - glog
  - gflags
  - opencv3
  - gtest


Replace "PATH/TO/USER/HOME" with your own username, e.g. "/home/yourusername" below.


CMAKE 3+
--------------------------------------------------------------------------------
wget https://cmake.org/files/v3.7/cmake-3.7.1.tar.gz
cd cmake-3.7.1/
mkdir build
cd build
cmake ..
make
make DESTDIR=/PATH/TO/USER/HOME install
--------------------------------------------------------------------------------


GLOG
--------------------------------------------------------------------------------
git clone https://github.com/google/glog.git
cd glog
vim configure
    => set m4 version from 14 to 13
./configure --prefix=/PATH/TO/USER/HOME/
make
make install
automake --add-missing
make install
    => this forced me to reinstall gflags (it was installed before)
--------------------------------------------------------------------------------


GFLAGS
--------------------------------------------------------------------------------
git clone https://github.com/gflags/gflags.git
cd gflags
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/PATH/TO/USER/HOME ..
vim CMakeCache
    => change line
          CMAKE_CXX_FLAGS:STRING=
       to
          CMAKE_CXX_FLAGS:STRING=-fPIC
make test
make install
--------------------------------------------------------------------------------


GTEST
--------------------------------------------------------------------------------
git clone https://github.com/google/googletest.git
cd googletest
mkdir build
cd build
cmake -D CMAKE_INSTALL_PREFIX=/PATH/TO/USER/HOME ..
make
make install
--------------------------------------------------------------------------------


OPENCV 3.2+
--------------------------------------------------------------------------------
wget http://downloads.sourceforge.net/project/opencvlibrary/opencv-unix/3.2.0/opencv-3.2.0.zip
unzip opencv-3.2.0.zip
cd opencv-3.2.0
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/PATH/TO/USER/HOME ..
make
make install
--------------------------------------------------------------------------------


BASIC TEST (SEE IF EVERYTHING WORKS):

CMakeLists.txt
 | cmake_minimum_required(VERSION 2.8)
 | project(Tests)
 |
 | find_package(OpenCV REQUIRED)
 | include_directories(${OpenCV_INCLUDE_DIRS})
 | 
 | file(GLOB SRC "${CMAKE_CURRENT_SOURCE_DIR}/src/*")
 | 
 | # Require C++ 11.
 | SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
 | 
 | add_executable(
 |   Test
 |   src/test.cpp
 | )
 | target_link_libraries(
 |   Test
 |   pthread
 |   glog
 |   gflags
 |   ${OpenCV_LIBS}
 | )

src/test.cpp:
 | #include <iostream>
 | #include "opencv2/core/core.hpp"
 | #include "gflags/gflags.h"
 | #include "glog/logging.h"
 | 
 | using namespace std;
 | 
 | DEFINE_string(testarg, "", "Test argument...");
 | 
 | int main(int argc, char** argv) {
 |   gflags::ParseCommandLineFlags(&argc, &argv, true);
 |   cout << "Hello, world!" << endl;
 |   LOG(INFO) << "Argument was: " << FLAGS_testarg;
 |   cv::Mat m = (cv::Mat_<double>(3, 3)
 |       << 5, 6, 7,
 |          8, 9, 0,
 |          1, 2, 3);
 |   cout << m << endl;
 |   return 0;
 | }

Then the following should work:
 $ mkdir build
 $ cd build
 $ cmake ..
 $ make
 $ ./Test
