=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)
|
|
|
|

|
|
|
|
=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 bytecode 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.
