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 Re-
lease).
–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-in-
stalled 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 –compo-
nents. In most cases, components correspond directly to LLVM li-
braries. Useful “virtual” components include:
all
Includes all LLVM libraries. The default if no components are spec-
ified.
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.
