Re: Error in package building : error[E0463]: can't find crate for `openssl_src`

     Hello Hamzeh,  

  
Take a look at gnu/packages/crates-io.scm for other examples of rust-openssl. 
We try to avoid vendored sources. Recent versions of rust-openssl-sys also 
complicate this by requiring particular versions of openssl.    While it’s nice 
that they are explicit about the dependency, we don’t have them in the package 
set.   
  

  
Finally and probably most immediately useful to you, check out 
gnu/packages/rust-apps.scm. You may need to set the OPENSSL_DIR environment 
variable to the location of the openssl dependency.
  

  
I see the “vendored” feature in the Cargo.toml that makes me think this may not 
work, but that would be where I start.   
  

  
Good luck,
  

  
John
