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
       --assertion-mode
	  Print	the assertion mode used	when LLVM was built (ON	or OFF).

       --bindir
	  Print	the installation directory for LLVM binaries.

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

       --build-system
	  Print	the build system used to build LLVM (e.g. cmake	or gn).

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

       --cmakedir
	  Print	the installation directory for LLVM CMake modules.

       --components
	  Print	all valid component names.

       --cppflags
	  Print	the C preprocessor flags needed	to use LLVM headers.

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

       --has-rtti
	  Print	whether	or not LLVM was	built with rtti	(YES or	NO).

       --help
	  Print	a summary of llvm-config arguments.

       --host-target
	  Print	the target triple used to configure LLVM.

       --ignore-libllvm
	  Ignore libLLVM and link component libraries instead.

       --includedir
	  Print	the installation directory for LLVM headers.

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

       --libdir
	  Print	the installation directory for LLVM libraries.

       --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.

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

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

       --link-shared
	  Link the components as shared	libraries.

       --link-static
	  Link the component libraries statically.

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

       --prefix
	  Print	the installation prefix	for LLVM.

       --shared-mode
	  Print	how the	provided components can	be collectively	linked (shared
	  or static).

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

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

       --version
	  Print	the version number of LLVM.

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

       all
	  Includes all LLVM libraries.	The default if no components are spec-
	  ified.

       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.
