| =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. |
