LLVM-CONFIG(1) LLVM 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 --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
--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.
