# If you want to use a custom linker with Cargo, Cargo requires that you
|
|
# specify it in Cargo.toml or via the matching environment variable.
|
|
# Passing extra options to the linker is possible with Cargo via
|
|
# RUSTFLAGS='-C link-args', but testing showed that doing this reliably
|
|
# was difficult.
|
|
#
|
|
# Our solution to these problems is to use this wrapper script. We pass
|
|
# in the LD and the LDFLAGS to use via environment variables. Note that
|
|
# we do *not* quote either MOZ_CARGO_WRAP variable:
|
|
#
|
|
# * MOZ_CARGO_WRAP_LD is equivalent to CC on Unix-y platforms, and CC
|
|
# frequently has additional arguments in addition to the compiler
|
|
# itself.
|
|
# * MOZ_CARGO_WRAP_LDFLAGS contains space-separated arguments to pass,
|
|
# and not quoting it ensures that either of those arguments is passed
|
|
# as a separate argument to the actual LD.
|
|
#
|
|
# $@ is doubly quoted for the eval. See bug 1418598.
