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  without  -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 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).

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

       –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 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.
