Using clang with YouCompleteMe for IntelliSense auto-complete in Vim

Installing vim (must be 7.3.584 w/ python2 support):

If you have root:

https://github.com/Valloric/YouCompleteMe/wiki/Building-Vim-from-source

If you don't have root:

http://www.vim.org/sources.php
Copy the version you want, extract and cd into it
./configure --with-features=huge --enable-multibyte --enable-rubyinterp --enable-pythoninterp --with-python-config-dir=/tools/devkits/lnx64/python-2.7.5/lib/python2.7/config/ --enable-perlinterp --enable-luainterp --enable-gui=gtk2 --enable-cscope --prefix=<install_dir>
# I used ~/vim74_install/
# Also I had some problems with ruby, so I removed --enable-rubyinterp

make
make install

# remember to setup paths to bin e.g. setenv PATH ~/vim74_install/bin:$PATH

gvim --version

Installing clang (only if your OS isn't supported here http://llvm.org/releases/download.html#3.3)

http://clang.llvm.org/get_started.html

Download llvm, clang, compiler rt, and clang tools extra, from:

http://llvm.org/releases/download.html#3.3

tar xzf llvm-3.4.1.src.tar.gz 

mv llvm-3.4.1.src llvm-3.4.1

cd llvm-3.4.1/tools/

tar xzf ../../cfe-3.4.1.src.tar.gz 

mv cfe-3.4.1.src clang

cd ../..

cd llvm-3.4.1/tools/clang/tools

tar xzf ../../../../clang-tools-extra-3.4.src.tar.gz 

mv clang-tools-extra-3.4/ extra/

cd ../../../..

cd llvm-3.4.1/projects/

tar xzf ../../compiler-rt-3.4.src.tar.gz 

mv compiler-rt-3.4/ compiler-rt/

cd ../..

mkdir llvm-3.4.1_build/

cd llvm-3.4.1_build/

../llvm-3.4.1/configure --prefix=~/llvm-3.4.1_install

make

#mkdir llvm-3.4.1_linstall/

# remember to setup paths to bin e.g. setenv PATH ~/llvm-3.4.1_linstall/bin:$PATH

Installing CMake

wget http://www.cmake.org/files/v2.8/cmake-2.8.12.2.tar.gz
tar xzf cmake-2.8.12.2.tar.gz
cd cmake-2.8.12.2
./configure --prefix=<install_dir>
# I used ~/cmake-2.8.12.2_install/

# ERROR: version `GLIBCXX_3.4.15' not found
# Luckily I had gcc-4.8.2 installed which has libstdc++.so.6 with the correct GLIBCXX.  To point to that I used:
setenv LD_LIBRARY_PATH /tools/devkits/lnx64/gcc-4.8.2/lib64:$LD_LIBRARY_PATH
# rerun config

gmake

# remember to setup paths to bin e.g. setenv PATH ~/cmake-2.8.12.2_install//bin:$PATH

cmake -version

Installing YouCompleteMe

Reference: https://github.com/Valloric/YouCompleteMe && http://valloric.github.io/YouCompleteMe/

cd ~/.vim/bundle/
git clone https://github.com/Valloric/YouCompleteMe
cd YouCompleteMe
git submodule update --init --recursive
#./install.sh --clang-completer << didn't work for me

Download the binary unless you built clang:
http://llvm.org/releases/download.html#3.3
Extract the archive and this path that you extract llvm to is used below as ~/ycm_temp/llvm_root_dircd

cmake -G "Unix Makefiles" -DPATH_TO_LLVM_ROOT=~/ycm_temp/llvm_root_dir . ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp

make ycm_support_libs

# -- If you get this:

# Then the c++/cpp/g++/cpp compile being used by cmake is incorrect.  This is represented by 

# CMAKE_CXX_COMPILER && CMAKE_C_COMPILER
# -- Then do this:

Being Pragmatic

Intro

1. Care about your craft
2. Think! About your work
3. Provide options, no excuses
4. Don't live with broken windows
5. Be a catalyst for change
6. Remember the big picture
7. Make quality a requirements issue
8. Invest regularly in your knowledge
9. Critically analyze what you read and hear
10. It's both what you say and how you say it

Thinking
    What
    Interest
    Sophistication
    Detail
    Own
    Motivation

• Know what you want to say
• Know your audience
• Choose your moment
• Choose a style
• Make it look good
• Involve the audience
• Be a listener
• Respond

Tackling

1. DRY - Don't Repeat Yourself
2. Make it easy to reuse
3. Eliminate effects between unrelated objects
4. There are no final decisions
5. Use tracer bullets to find the target
6. Prototype to learn
7. Program close to the problem domain
8. Estimate to avoid surprises
9. Iterate the schedule with the code

Tools

1. Keep knowledge in plain text
2. Use command shells
3. Use a single editor well
4. Always use source control management software
5. Fix the problem not the blame
6. Don't panic
7. Take the signs for what they are
8. Don't assume it - Prove it
9. Learn a text manipulation language

• Debugging steps

1. Are you seeing a symptom, or the root cause?
2. Write down the problem as in an email to a co-worker
3. If we see problems and the tests are passing, then are the tests complete?
4. Where else does this problem exist, or need to be checked?

__fix__
the problem is associated with x window forwarding

I was in a vnc session initiated from user admin and the .run file I was trying to execute was not able to forward the window through the terminal to the vncserver I was using

root cause is still unknown

_workaround_
start a vnc session under root (not generally supported) and then execute the file

this correctly opened the GUI
