Hifi linux build - update 001

# Notes from setting up a linuxmint-16 laptop to be a hifi dev environment.
# We know at a minimum we need these packages:

    apt-get install git g++ cmake

# Clone the repo:

    cd $HOME
    mkdir src
    cd src
    git clone https://github.com/highfidelity/hifi.git

# Configure the build:

    mkdir build
    cd build
    cmake ../

# The configure fails for lack of GLM:
#
# "CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108 (message):
#  Could NOT find GLM (missing: GLM_INCLUDE_DIR)"

# Downloaded GLM via http://glm.g-truc.net/0.9.5/index.html
# as per the instructions in .../hifi/BUILD.md.
# (I could have put glm in my homedir, but it wasn't something I wanted to clutter up my homedir
# backup, so instead I unpacked into /usr/local/src/ using admin priviledges.)

    sudo mkdir /usr/local/src/glm-0.9.5.3
    cd ~/Downloads/
    sudo unzip -d /usr/local/src/glm-0.9.5.3 glm-0.9.5.3.zip

# I added this line to my ~/.bashrc:

export GLM_ROOT_DIR="/usr/local/src/glm-0.9.5.3/glm"

    source ~/.bashrc
    cd ~/src/hifi/build
    cmake ../

# The configure fails for lack of Qt:
#
# CMake Error at cmake/macros/SetupHifiProject.cmake:29 (find_package):
#  By not providing "FindQt5Core.cmake" in CMAKE_MODULE_PATH this project has
#  asked CMake to find a package configuration file provided by "Qt5Core", but
#  CMake did not find one.

# Download Qt at http://qt-project.org/downloads
# as per the instructions in .../hifi/BUILD.md.
# (I downloaded the 64bit version since I'm using 64-bit linuxmint)

    cd ~/Downloads

# The download is a script, but we must set the executable bit to run it:

    chmod a+x qt-opensource-linux-x64-1.5.0-2-online.run

# (Since I'm running this as a regular user but I want to install it in a protected directory
# I temporarily make the directory readable):

    sudo chmod o+w /usr/local/src

# Run the script (this can take several minutes to download some stuff).
# Install in:  /usr/local/src/Qt.
# Cleanup permissions when done.

    sudo chown -R root.root /usr/local/src/Qt
    sudo chmod go-w /usr/local/src
    sudo chmod -R go-w /usr/local/src/Qt

# add another environment variable to .bashrc

export QT_CMAKE_PREFIX_PATH=/usr/local/src/Qt/5.2.1/gcc_64/lib/cmake

    source ~/.bashrc
    cd ~/src/hifi/build
    cmake ../

# Examining the cmake logs suggests some lib headers are missing:

    sudo apt-get install libdrm-dev libgl1-mesa-dev zlib1g-dev

# Try again:

    cmake ../

# The configure may warn that it cannot find: P11_KIT, guile, and crywrap.
# It is okay to ignore these dependencies -- hifi does not use them.

# (I built as regular user and then installed with admin priviledges.  Again I didn't
# want to clutter my homedir with a lib package that I didn't want included in my
# personal backups).

    make
    sudo make install

# Go back to the hifi directory and try cmake...

    cd ~/src/hifi/build
    cmake ../

# Cmake is now complaining that it can't find GLUT

    sudo apt-get install freeglut3 freeglut3-dev

# cmake still can't find GLUT, and is also complaining about QXMPP.
# We can ignore the QXMPP warning because it is optional but the GLUT issues must
# be solved.

# After a bit of online research and poking around I figured out (can't remember how)
# that installing these packages solves the GLUT problems:

    sudo apt-get install libxmu-dev libxi-dev

EDIT:

# Openssl was recently added as a dependency.

    sudo apt-get install libssl-dev:amd64
