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.
