Cling - The Interactive C++ Interpreter

Philippe Canal 7312683eda Allocate Expr on a custom address to be able to release memory. We now use operator new with placement to memory explicit allocated in the routine (rather than the ASTContext) so that we can release this memory at the end of the function. The memory is allocated via a vector of object large enough to hold the OpaqueExprRef.		2013-08-26 00:10:54 +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.
