# This is a shim Cargo.toml which serves as a proxy for building the standard
|
||
|
|
# library. The reason for this is a little subtle, as one might reasonably
|
||
|
|
# expect that we just `cargo build` the standard library itself.
|
||
|
|
#
|
||
|
|
# One of the output artifacts for the standard library is a dynamic library, and
|
||
|
|
# on platforms like OSX the name of the output artifact is actually encoded into
|
||
|
|
# the library itself (similar to a soname on Linux). When the library is linked
|
||
|
|
# against, this encoded name is what's literally looked for at runtime when the
|
||
|
|
# dynamic loader is probing for libraries.
|
||
|
|
#
|
||
|
|
# Cargo, however, by default will not mangle the output filename of the
|
||
|
|
# top-level target. If we were to run `cargo build` on libstd itself, we would
|
||
|
|
# generate a file `libstd.so`. When installing, however, this file is called
|
||
|
|
# something like `libstd-abcdef0123.so`. On OSX at least this causes a failure
|
||
|
|
# at runtime because the encoded "soname" is `libstd.so`, not what the file is
|
||
|
|
# actually called.
|
||
|
|
#
|
||
|
|
# By using this shim library to build the standard library by proxy we sidestep
|
||
|
|
# this problem. The standard library is built with mangled hex already in its
|
||
|
|
# name so there's nothing extra we need to do.
