# Upstream rustc still assumes that musl = static[1]. The fix for
|
|
# this is to disable crt-static by default for non-static musl
|
|
# targets.
|
|
#
|
|
# For every package apart from Cargo, we can fix this by just
|
|
# patching rustc to not have crt-static by default. But Cargo is
|
|
# built with the upstream bootstrap binary for rustc, which we can't
|
|
# easily patch. This means we need to find another way to make sure
|
|
# crt-static is not used during the build of pkgsMusl.cargo.
|
|
#
|
|
# By default, Cargo doesn't apply RUSTFLAGS when building build.rs
|
|
# if --target is passed, so the only good way to set -crt-static for
|
|
# build.rs files used in the Cargo build is to use the unstable
|
|
# -Zhost-config Cargo feature. This allows us to specify flags that
|
|
# should be passed to rustc when building for the build platform.
|
|
# We also need to use -Ztarget-applies-to-host, because using
|
|
# -Zhost-config requires it.
|
|
#
|
|
# When doing this, we also have to specify the linker, or cargo
|
|
# won't pass a -C linker= argument to rustc. This will make rustc
|
|
# try to use its default value of "cc", which won't be available
|
|
# when cross-compiling.
