"LLVM-CONFIG" "1" "2023-10-21" "16" "LLVM"
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:
NDENT 0.0 NDENT 3.5 g++ \(gallvm-config --cxxflags\(ga -o HowToUseJIT.o -c HowToUseJIT.cpp g++ \(gallvm-config --ldflags\(ga -o HowToUseJIT HowToUseJIT.o \e \(gallvm-config --libs engine bcreader scalaropts\(gaNINDENT NINDENT
OPTIONS
--assertion-mode
NDENT 0.0 NDENT 3.5 Print the assertion mode used when LLVM was built (ON or OFF).
NINDENT NINDENT --bindir
NDENT 0.0 NDENT 3.5 Print the installation directory for LLVM binaries.
NINDENT NINDENT --build-mode
NDENT 0.0 NDENT 3.5 Print the build mode used when LLVM was built (e.g. Debug or Release).
NINDENT NINDENT --build-system
NDENT 0.0 NDENT 3.5 Print the build system used to build LLVM (e.g. cmake or gn).
NINDENT NINDENT --cflags
NDENT 0.0 NDENT 3.5 Print the C compiler flags needed to use LLVM headers.
NINDENT NINDENT --cmakedir
NDENT 0.0 NDENT 3.5 Print the installation directory for LLVM CMake modules.
NINDENT NINDENT --components
NDENT 0.0 NDENT 3.5 Print all valid component names.
NINDENT NINDENT --cppflags
NDENT 0.0 NDENT 3.5 Print the C preprocessor flags needed to use LLVM headers.
NINDENT NINDENT --cxxflags
NDENT 0.0 NDENT 3.5 Print the C++ compiler flags needed to use LLVM headers.
NINDENT NINDENT --has-rtti
NDENT 0.0 NDENT 3.5 Print whether or not LLVM was built with rtti (YES or NO).
NINDENT NINDENT --help
NDENT 0.0 NDENT 3.5 Print a summary of llvm-config arguments.
NINDENT NINDENT --host-target
NDENT 0.0 NDENT 3.5 Print the target triple used to configure LLVM.
NINDENT NINDENT --ignore-libllvm
NDENT 0.0 NDENT 3.5 Ignore libLLVM and link component libraries instead.
NINDENT NINDENT --includedir
NDENT 0.0 NDENT 3.5 Print the installation directory for LLVM headers.
NINDENT NINDENT --ldflags
NDENT 0.0 NDENT 3.5 Print the flags needed to link against LLVM libraries.
NINDENT NINDENT --libdir
NDENT 0.0 NDENT 3.5 Print the installation directory for LLVM libraries.
NINDENT NINDENT --libfiles
NDENT 0.0 NDENT 3.5 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.
NINDENT NINDENT --libnames
NDENT 0.0 NDENT 3.5 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.
NINDENT NINDENT --libs
NDENT 0.0 NDENT 3.5 Print all the libraries needed to link against the specified LLVM
components, including any dependencies.
NINDENT NINDENT --link-shared
NDENT 0.0 NDENT 3.5 Link the components as shared libraries.
NINDENT NINDENT --link-static
NDENT 0.0 NDENT 3.5 Link the component libraries statically.
NINDENT NINDENT --obj-root
NDENT 0.0 NDENT 3.5 Print the object root used to build LLVM.
NINDENT NINDENT --prefix
NDENT 0.0 NDENT 3.5 Print the installation prefix for LLVM.
NINDENT NINDENT --shared-mode
NDENT 0.0 NDENT 3.5 Print how the provided components can be collectively linked (shared or static).
NINDENT NINDENT --system-libs
NDENT 0.0 NDENT 3.5 Print all the system libraries needed to link against the specified LLVM
components, including any dependencies.
NINDENT NINDENT --targets-built
NDENT 0.0 NDENT 3.5 Print the component names for all targets supported by this copy of LLVM.
NINDENT NINDENT --version
NDENT 0.0 NDENT 3.5 Print the version number of LLVM.
NINDENT NINDENT COMPONENTS
To print a list of all available components, run llvm-config
--components. In most cases, components correspond directly to LLVM
libraries. Useful \(dqvirtual\(dq components include:
all
NDENT 0.0 NDENT 3.5 Includes all LLVM libraries. The default if no components are specified.
NINDENT NINDENT backend
NDENT 0.0 NDENT 3.5 Includes either a native backend or the C backend.
NINDENT NINDENT engine
NDENT 0.0 NDENT 3.5 Includes either a native JIT or the bitcode interpreter.
NINDENT NINDENT EXIT STATUS
If llvm-config succeeds, it will exit with 0. Otherwise, if an error
occurs, it will exit with a non-zero value.
