NAME
       llvm-config - Print LLVM compilation options

SYNOPSIS
       llvm-config option [components...]

DESCRIPTION
       llvm-config makes it easier to build applications that use LLVM.  It
       can print the compiler flags, linker flags and object libraries needed
       to link against LLVM.

EXAMPLES
       To link against the JIT:

         g++ `llvm-config --cxxflags` -o HowToUseJIT.o -c HowToUseJIT.cpp
         g++ `llvm-config --ldflags` -o HowToUseJIT HowToUseJIT.o \
             `llvm-config --libs engine bcreader scalaropts`

OPTIONS
       --version
           Print the version number of LLVM.

       -help
           Print a summary of llvm-config arguments.

       --prefix
           Print the installation prefix for LLVM.

       --src-root
           Print the source root from which LLVM was built.

       --obj-root
           Print the object root used to build LLVM.

       --bindir
           Print the installation directory for LLVM binaries.

       --includedir
           Print the installation directory for LLVM headers.

       --libdir
           Print the installation directory for LLVM libraries.

       --cxxflags
           Print the C++ compiler flags needed to use LLVM headers.

       --ldflags
           Print the flags needed to link against LLVM libraries.

       --libs
           Print all the libraries needed to link against the specified LLVM
           components, including any dependencies.

       --libnames
           Similar to --libs, but prints the bare filenames of the libraries
           without -l or pathnames.  Useful for linking against a not-yet-
           installed copy of LLVM.

       --libfiles
           Similar to --libs, but print the full path to each library file.
           This is useful when creating makefile dependencies, to ensure that
           a tool is relinked if any library it uses changes.

       --components
           Print all valid component names.

       --targets-built
           Print the component names for all targets supported by this copy of
           LLVM.

       --build-mode
           Print the build mode used when LLVM was built (e.g. Debug or
           Release)

COMPONENTS
       To print a list of all available components, run llvm-config
       --components.  In most cases, components correspond directly to LLVM
       libraries.  Useful "virtual" components include:

       all Includes all LLVM libaries.  The default if no components are
           specified.

       backend
           Includes either a native backend or the C backend.

       engine
           Includes either a native JIT or the bitcode interpreter.

EXIT STATUS
       If llvm-config succeeds, it will exit with 0.  Otherwise, if an error
       occurs, it will exit with a non-zero value.
