Failed to open OpenSSL headers on Ubuntu

[SamuelWolf0]

When running cargo build --release the following error occurs:

error: failed to run custom build command for openssl-sys v0.9.59

Failed to find OpenSSL development headers.

You can try fixing this setting the OPENSSL_DIR environment variable pointing to your OpenSSL installation or installing OpenSSL headers package specific to your distribution:

  # On Ubuntu
  sudo apt-get install libssl-dev
  # On Arch Linux
  sudo pacman -S openssl
  # On Fedora
  sudo dnf install openssl-devel

See rust-openssl README for more information:

  https://github.com/sfackler/rust-openssl#linux

', /home/ubuntu/.cargo/registry/src/github.com-1ecc6299db9ec823/openssl-sys-0.9.59/build/main.rs:141:13 note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

All required dependencies are installed correctly. To which path do you have to set the OPENSSL_DIR variables?

Try running: cargo add openssl-sys then, cargo update cargo build --release

[SamuelWolf0]

That fixes the error. But executing cargo build --release now just stops at building the libindy library and won´t finish that task

Yes I noticed and I have opened new issues for it, see link below. https://github.com/hyperledger/indy-sdk/issues/2588

@SamuelWolf0 I have solved the library won't finish the task you highlighted above. I was using AWS ubuntu on free tier 8GB. I was getting the same stoppage, I now increased the memory storage to 20GB and it is now loading but am getting different error. Will keep troubleshooting to see if I can fix

Hi guys! I don't know if this message could help but I had the same error with openssl and I was able to solve the problem with @chrizteroo message (this one).

This is my current setup:

• Ubuntu 22.04 jammy on WSL
• cargo 1.68.2 (6feb7c9cf 2023-03-26)
• OpenSSL 3.0.2 15 Mar 2022 (Library: OpenSSL 3.0.2 15 Mar 2022)
• rustc 1.68.2 (9eb3afe9e 2023-03-27)
• libssl-dev 3.0.2-0ubuntu1.8

Maybe @SamuelWolf0 you can try to update your versions.
