==Installing LLVM & Clang from svn (tested on linux) inst_llvm.sh==
Use this if you cant get a pre-compiled llvm/clang or if you want to have the lastest clang.

This script installs llvm & clang from source, re-running will update the installation.
<source lang="bash">#!/bin/sh

SRCDIR="/opt/src"
INSTDIR="/opt/llvm"

echo ""

if [ -d $SRCDIR/llvm/.svn ] ; then
echo "Updating "$SRCDIR"/llvm ..."
svn up $SRCDIR/llvm $SRCDIR/llvm/tools/clang
else
echo "Checking out "$SRCDIR"/llvm ..."
svn checkout http://llvm.org/svn/llvm-project/llvm/trunk $SRCDIR/llvm
svn checkout http://llvm.org/svn/llvm-project/cfe/trunk $SRCDIR/llvm/tools/clang
fi

rm -rf $INSTDIR

mkdir $SRCDIR/llvm_cmake
cd $SRCDIR/llvm_cmake

echo ""
echo "Building..."

cmake ../llvm \
-DCMAKE_INSTALL_PREFIX:STRING=$INSTDIR \
-DCMAKE_BUILD_TYPE:STRING=Debug \
-DLLVM_ENABLE_THREADS:BOOL=ON

make -j6

echo ""
echo "Installing..."

make install

cp $SRCDIR/llvm/tools/clang/tools/scan-view/scan-view $INSTDIR/bin/
cp $SRCDIR/llvm/tools/clang/tools/scan-view/*.py $INSTDIR/bin/

cp $SRCDIR/llvm/tools/clang/tools/scan-build/scan-build $INSTDIR/bin/
cp $SRCDIR/llvm/tools/clang/tools/scan-build/ccc-analyzer $INSTDIR/bin/
cp $SRCDIR/llvm/tools/clang/tools/scan-build/c++-analyzer $INSTDIR/bin/
cp $SRCDIR/llvm/tools/clang/tools/scan-build/sorttable.js $INSTDIR/bin/
cp $SRCDIR/llvm/tools/clang/tools/scan-build/scanview.css $INSTDIR/bin/

echo ""
echo "Done!"
</source>

== Configuring CMake ==
Assuming you know about building with cmake and blender
see: [[Dev:2.5/Doc/Building_Blender/Linux/Ubuntu/CMake]]

clang will need to be added to the $PATH, edit your ~/.bashrc and add this line.
export PATH=$PATH:/opt/llvm/bin

Run cmake with these args.

<source lang="bash">
cmake ../blender \
-DCMAKE_CXX_COMPILER:FILEPATH=/opt/clang/bin/c++-analyzer \
-DCMAKE_C_COMPILER:FILEPATH=/opt/clang/bin/ccc-analyzer
</source>

note:
* You may need to explicitly add in GCC includes, eg:<br>-DCMAKE_CXX_FLAGS:STRING="-I/usr/include/c++/4.5.2 -I/usr/include/c++/4.5.2/x86_64-unknown-linux-gnu"
* /usr/share/clang/scan-build/c++-analyzer is the default path if you use a pre-compiled build
* on GCC 4.6 you may get an error with __extern_always_inline<br>In this case you can use -DCMAKE_CXX_FLAGS:STRING="-D__extern_always_inline=inline"

== Compiling Blender ==

The usual make in the cmake dir will build blender however clang can output nice error html like this
http://www.graphicall.org/ftp/ideasman42/2011-01-07-2/

To get this html output run...
<source lang=bash>
export CCC_ANALYZER_CPLUSPLUS=1 # for C++ analysis
scan-build -o /tmp/clang make -j6
</source>
After building (takes about an 1.5 hrs for me), you will have a directory like /tmp/clang/2011-01-07-2/ with html ouput of scan-build.

== Continuous Static Checker Server ==
Currently we have blender static check running on a server.

* http://clang.blenderheads.org/trunk - Main Page
* http://clang.blenderheads.org/trunk.clang.txt - Build Output for LLVM/CLang
* http://clang.blenderheads.org/trunk.blender.txt - Build Output for Blender

This is doing C checks only because there is a header issue with clang and gcc headers on this system.
