Cling - The Interactive C++ Interpreter

Vassil Vassilev c2a0b5cece For now we will only work/check on declarations that are not deserialized. We don't want our null deref checker to deserialize the whole PCH/PCM. We should come up with an idea to work around it.		2013-08-22 13:50:56 +02:00

1.1 Dependencies

   CLING source depends on the LLVM [1] and CLANG [2] headers and libraries.
You will also need CMake [3] >= 2.6.1 or GNU Make to build all of those
packages and subversion [4] to get the source code.

   [1] http://llvm.org
   [2] http://clang.llvm.org
   [3] http://cmake.org
   [4] http://subversion.tigris.org/

1.2 Building

   To build LLVM and CLANG you must:

   * Check out the sources:

     mkdir src
     cd src
     svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm
     cd llvm/tools
     svn co http://llvm.org/svn/llvm-project/cfe/trunk clang
     svn co http://root.cern.ch/svn/root/trunk/interpreter/cling cling
     cd ..

   * Apply some patches

     cat tools/cling/patches/* | patch -p0

   * Configure, build and install them, either using CMake:

     cd ..
     mkdir build
     cd build
     cmake -DCMAKE_INSTALL_PREFIX=/some/install/dir \
           -DLLVM_TARGETS_TO_BUILD=CBackend\;CppBackend\;X86 \
           -DCMAKE_BUILD_TYPE=Debug \
           -DCMAKE_CXX_COMPILER=`which c++` \
           -DCMAKE_C_COMPILER=`which gcc` \
           ../llvm
     make
     make install

     or GNU Make (see ../src/configure --help for all options):

     cd ..
     mkdir build
     cd build
     ../llvm/configure --prefix=/some/install/dir
     make
     make install

2. U S A G E

   To interpret a C file type: "./cling test.c". To invoke cling in the
interactive mode type "cling" without file name.  Use ".L filename" to 
load libraries or C++ files.  Type C++ code at the prompt to interpret it.
