Cross-compilation to armv7l failed

[xavierfortier1]

Problem:

I am trying to cross compile spotify-player for armv7l and building aws-lc-sys breaks. I have all the dependencies to build it and every package used with their version is in the beginning of the log and the error is at the end.

Relevant details

AWS-LC for Rust version: v1.11.1

System information:

• CPU architecture host: x86_64
• CPU architecture target: armv7l
• name: Intel Core i7-8550u
• OS: Void Linux

I think the compiler is complaining about this section of code: (maybe?)

  // SHA-512 and SHA-512/256 are aligned to 8-byte words, SHA-512/224 is not.
  // If the digest size is not aligned to 8-byte words, we need to process the
  // non-word-aligned "trailer".
  if (md_len == SHA512_224_DIGEST_LENGTH) {
    uint64_t trailer;
    CRYPTO_store_u64_be(&trailer, sha->h[out_words]);
    OPENSSL_memcpy(out, &trailer, SHA512_224_DIGEST_LENGTH % 8);
  }

This logic appears correct to me (and I know this logic has been heavily tested), but I can see why the compiler might be concerned about it. We'll need to reproduce this compiler error in order to identify a potential fix.

One potential workaround would be to disable this compiler warning. You could try setting the following in your build environment:

export AWS_LC_SYS_CFLAGS="-Wno-stringop-overflow"

We'll update here when we make progress on this issue. Thanks!

Thanks for looking into this issue. I tested the workaround. At first, it didn't work because of the equal sign. It worked when I removed it, so here is a updated version for others:

export AWS_LC_SYS_CFLAGS="-Wno-stringop-overflow"

Great! Thanks! I updated my comment so that the workaround I suggest matches yours.
