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).
--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.
