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 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.
