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

--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 libaries. 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.
