-
- gen_link_script.py [--help] [--dryrun] <path/to/libcxx.so> <abi_libname>
-
- Generate a linker script that links libc++ to the proper ABI library.
- The script replaces the specified libc++ symlink.
- An example script for c++abi would look like "INPUT(libc++.so.1 -lc++abi)".
-
-Arguments
- <path/to/libcxx.so> - The top level symlink to the versioned libc++ shared
- library. This file is replaced with a linker script.
- <abi_libname> - The name of the ABI library to use in the linker script.
- The name must be one of [c++abi, stdc++, supc++, cxxrt].
-
-Exit Status:
- 0 if OK,
- 1 if the action failed.
