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 compo-
	nents, including any dependencies.

     --libnames
	Similar  to --libs, but prints the bare filenames of the libraries with-
	out -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 libraries.  The default if no  components  are  speci-
	fied.

     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 oc-
     curs, it will exit with a non-zero value.
