Get various configuration information needed to compile programs which use
|
||||
LLVM. Typically called from 'configure' scripts. Examples:
|
||||
llvm-config --cxxflags
|
||||
llvm-config --ldflags
|
||||
llvm-config --libs engine bcreader scalaropts
|
||||
|
||||
Options:
|
||||
--version Print LLVM version.
|
||||
--prefix Print the installation prefix.
|
||||
--src-root Print the source root LLVM was built from.
|
||||
--obj-root Print the object root used to build LLVM.
|
||||
--bindir Directory containing LLVM executables.
|
||||
--includedir Directory containing LLVM headers.
|
||||
--libdir Directory containing LLVM libraries.
|
||||
--cppflags C preprocessor flags for files that include LLVM headers.
|
||||
--cflags C compiler flags for files that include LLVM headers.
|
||||
--cxxflags C++ compiler flags for files that include LLVM headers.
|
||||
--ldflags Print Linker flags.
|
||||
--system-libs System Libraries needed to link against LLVM components.
|
||||
--libs Libraries needed to link against LLVM components.
|
||||
--libnames Bare library names for in-tree builds.
|
||||
--libfiles Fully qualified library filenames for makefile depends.
|
||||
--components List of all possible components.
|
||||
--targets-built List of all targets currently built.
|
||||
--host-target Target triple used to configure LLVM.
|
||||
--build-mode Print build mode of LLVM tree (e.g. Debug or Release).
|
||||
--assertion-mode Print assertion mode of LLVM tree (ON or OFF).
|
||||
--build-system Print the build system used to build LLVM (always cmake).
|
||||
--has-rtti Print whether or not LLVM was built with rtti (YES or NO).
|
||||
--has-global-isel Print whether or not LLVM was built with global-isel support (YES or NO).
|
||||
--shared-mode Print how the provided components can be collectively linked (\`shared\` or \`static\`).
|
||||
--link-shared Link the components as shared libraries.
|
||||
--link-static Link the component libraries statically.
|
||||
Typical components:
|
||||
all All LLVM libraries (default).
