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.
