=head1 NAME
llvm-config - Print LLVM compilation options
=head1 SYNOPSIS
B<llvm-config> I<option> [I<components>...]
=head1 DESCRIPTION
B<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.
=head1 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`
=head1 OPTIONS
=over
=item B<--version>
Print the version number of LLVM.
=item B<-help>
Print a summary of B<llvm-config> arguments.
=item B<--prefix>
Print the installation prefix for LLVM.
=item B<--src-root>
Print the source root from which LLVM was built.
=item B<--obj-root>
Print the object root used to build LLVM.
=item B<--bindir>
Print the installation directory for LLVM binaries.
=item B<--includedir>
Print the installation directory for LLVM headers.
=item B<--libdir>
Print the installation directory for LLVM libraries.
=item B<--cxxflags>
Print the C++ compiler flags needed to use LLVM headers.
=item B<--ldflags>
Print the flags needed to link against LLVM libraries.
=item B<--libs>
Print all the libraries needed to link against the specified LLVM
I<components>, including any dependencies.
=item B<--libnames>
Similar to B<--libs>, but prints the bare filenames of the libraries
without B<-l> or pathnames. Useful for linking against a not-yet-installed
copy of LLVM.
=item B<--libfiles>
Similar to B<--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.
=item B<--components>
Print all valid component names.
=item B<--targets-built>
Print the component names for all targets supported by this copy of LLVM.
=item B<--build-mode>
Print the build mode used when LLVM was built (e.g. Debug or Release)
=back
=head1 COMPONENTS
To print a list of all available components, run B<llvm-config
--components>. In most cases, components correspond directly to LLVM
libraries. Useful "virtual" components include:
=over
=item B<all>
Includes all LLVM libaries. The default if no components are specified.
=item B<backend>
Includes either a native backend or the C backend.
=item B<engine>
Includes either a native JIT or the bitcode interpreter.
=back
=head1 EXIT STATUS
If B<llvm-config> succeeds, it will exit with 0. Otherwise, if an error
occurs, it will exit with a non-zero value.
