cargo-zigbuild fails to compile crates that depend on linkme
jcrevier opened this issue · comments
It seems like cargo-zigbuild, or possibly zig itself might be stripping some parts of the data section more aggressively than the normal toolchain.
I ran into this when attempting to compile code that uses dnoltay's linkme crate.
I believe that the following code is enough to repro:
use linkme::distributed_slice;
#[distributed_slice]
pub static BENCHMARKS: [fn() ->()];
The output of compiling that with zigbuild for macos:
root@fc1f4ba9c8d7:/home/linkme-test# cargo zigbuild --target x86_64-apple-darwin
Compiling linkme-test v0.1.0 (/home/linkme-test)
error: linking with `/root/.cache/cargo-zigbuild/0.18.2/zigcc-x86_64-apple-darwin.sh` failed: exit status: 1
