Hi owner, when cargo build --target=aarch64-unknown-fuchsia some error occur,how to resolve this question?

build error log: Compiling libc v0.2.155 Compiling foreign-types-shared v0.1.1 Compiling cfg-if v1.0.0 Compiling bitflags v2.5.0 Compiling once_cell v1.19.0 Compiling openssl-sys v0.9.102 Compiling openssl-macros v0.1.1 error: failed to run custom build command for openssl-sys v0.9.102

Could not find directory of OpenSSL installation, and this -sys crate cannot proceed without this knowledge. If OpenSSL is installed and this crate had trouble finding it, you can set the OPENSSL_DIR environment variable for the compilation process.

Make sure you also have the development packages of openssl installed. For example, libssl-dev on Ubuntu or openssl-devel on Fedora.

If you're in a situation where you think the directory should be found automatically, please open a bug at https://github.com/sfackler/rust-openssl and include information about your system as well as this message.

How are you expecting this to work? It looks like you're trying to cross-compile from x86 Linux to aarch64 Fuchsia? You need a version of OpenSSL to link to. Unfortunately I don't think openssl-src supports Fuchsia, so I think you'll need to do one of:

  1. Add support for Fuchsia to openssl-src, allowing you to use that to build OpenSSL and then you can use the vendored feature
  2. Obtain a version of OpenSSL for AArch64 Fuchsia and configure pkg-config for cross compilation https://docs.rs/pkg-config/latest/pkg_config/#cross-compilation
  3. Cross-compile OpenSSL yourself and configure the openssl crate to use that https://docs.rs/openssl/latest/openssl/#manual
