LLVM-CONFIG(1)			      LLVM			  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
     --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 Release).

     --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 with-
	out -l or pathnames.  Useful for  linking  against  a  not-yet-installed
	copy of LLVM.

     --libs
	Print all the libraries needed to link against the specified LLVM compo-
	nents, 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 --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.
