1 llvm-config - Print LLVM compilation options
2 ============================================
9 **llvm-config** *option* [*components*...]
16 **llvm-config** makes it easier to build applications that use LLVM. It can
17 print the compiler flags, linker flags and object libraries needed to link
25 To link against the JIT:
30 g++ `llvm-config --cxxflags` -o HowToUseJIT.o -c HowToUseJIT.cpp
31 g++ `llvm-config --ldflags` -o HowToUseJIT HowToUseJIT.o \
32 `llvm-config --libs engine bcreader scalaropts`
43 Print the version number of LLVM.
49 Print a summary of **llvm-config** arguments.
55 Print the installation prefix for LLVM.
61 Print the source root from which LLVM was built.
67 Print the object root used to build LLVM.
73 Print the installation directory for LLVM binaries.
79 Print the installation directory for LLVM headers.
85 Print the installation directory for LLVM libraries.
91 Print the C++ compiler flags needed to use LLVM headers.
97 Print the flags needed to link against LLVM libraries.
103 Print all the libraries needed to link against the specified LLVM
104 *components*, including any dependencies.
110 Similar to **--libs**, but prints the bare filenames of the libraries
111 without **-l** or pathnames. Useful for linking against a not-yet-installed
118 Similar to **--libs**, but print the full path to each library file. This is
119 useful when creating makefile dependencies, to ensure that a tool is relinked if
120 any library it uses changes.
126 Print all valid component names.
132 Print the component names for all targets supported by this copy of LLVM.
138 Print the build mode used when LLVM was built (e.g. Debug or Release)
147 To print a list of all available components, run **llvm-config
148 --components**. In most cases, components correspond directly to LLVM
149 libraries. Useful "virtual" components include:
154 Includes all LLVM libraries. The default if no components are specified.
160 Includes either a native backend or the C backend.
166 Includes either a native JIT or the bitcode interpreter.
175 If **llvm-config** succeeds, it will exit with 0. Otherwise, if an error
176 occurs, it will exit with a non-zero value.
