• I have read the troubleshooting section and still think this is a bug.

Describe the bug you encountered:

Until fd 8.7.0 build with --target armv7-unknown-linux-gnueabi works fine.

For fd 8.7.1 there is a linker error

error: linking with `/spksrc/toolchain/syno-hi3535-6.2.4/work/arm-cortexa9-linux-gnueabi/bin/arm-cortexa9-linux-gnueabi-gcc` failed: exit status: 1

error: could not compile `fd-find` (bin "fd") due to previous error

probably this is an issue with the older synology toolchain for hi3535 arch.

for other targets/toolchains the build succeeds:

• x86_64-unknown-linux-gnu
• i686-unknown-linux-gnu
• armv5te-unknown-linux-gnueabi (with fix: Multiple definitions of __sync_fetch_and_add_4 et al. rust-lang/compiler-builtins#420 (comment))
• armv7-unknown-linux-gnueabihf
• aarch64-unknown-linux-gnu
• powerpc-unknown-linux-gnu

Thank you. It looks like this is a problem in a dependency (binutils). Do you think it should be reported upstream?

Thank you. It looks like this is a problem in a dependency (binutils). Do you think it should be reported upstream?

As this version of binutils is provided part of the Synology toolchain, and that support from Synology for this specific architecture has ended, there isn't much that can be done from an upstreaming point of view. Further as it uses v2.24 of binutils dating from 2013.

I've hit this issue once again SynoCommunity/spksrc#6210 where it no longer "only" fails to build with fd >= 8.7.1, but it's now also failing with latest functional version (8.7.0) in conjunction with newer rust >= 1.80.1. We can workaround that by fixing rust version to 1.7x but this leaves a gap for future (and limited) support for updated apps.

If there is anything that can be done on fd sources side to fix this would be really nice albeit that could be a burden to maintain later on.
