Hi,

I have this error when trying to cross compile with cross :

error: failed to run custom build command for `openssl-sys v0.9.75`

Caused by:
  process didn't exit successfully: `/target/debug/build/openssl-sys-18e44fca85da1ee1/build-script-main` (exit status: 101)

  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.

Does anyone already resolved this issue ?

Thank for your help :)

Sounds like an issue with cross, https://github.com/cross-rs/cross/issues/229

One proposed solution would be to pass "vendored" to openssl, to use a prebuilt version of the library. My lib has a "vendored-openssl" feature that corresponds to that, so you could try using it. I can't tell you if this would work or not, but it might.
