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.
