LLVM-CONFIG(1)		      LLVM Command Guide		LLVM-CONFIG(1)

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.
