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 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.
