Hi,
I stated to learn Rust and got stocked when using reqwest- it having an dependency on rust-openssl. And openssl I'm not able to build.
To have shorter try-and-err cycles, I set up a simple project, only using rust-openssl.
Here my Cargo.toml:

[package]
name = "build_openssl"
version = "0.1.0"
edition = "2021"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
#openssl = {version = "0.10.45", feature = "vendored"}
#openssl-sys = {version = "0.9.80", feature = "vendored"}
openssl = {version = "0.10.45"}
openssl-sys = {version = "0.9.80"}

.cargo/config.toml continas

[build]
target = "wasm32-unknown-unknown"

I inseted some println! macros (output recognizable by 'Obioma: ...') in the build rust code, trying to understand the topic - but nada. Got stocked.
Here the output from cargo build -vv

warning: build failed, waiting for other jobs to finish...

The referenced directory  usr/lib/i386-linux-gnu contains libcrypto.so and libssl.so, the later linked to libssl3.so.
To be on the safe side, I downloaded the openssl sources and compiled it into a extra folder, using that as target (changing all the environment vars).

I also tried export

RUSTFLAGS=-L ssl='/home/gunter/Apps/openssl-3.0.7/libssl.so'

, no success. I have not too many ideas what else to fix, any suggestions?

Thx in advance

Hi Steven,
thx, will investigate into that direction.
In the meantime I saw that in the Cargo.toml for openssl-sys version 1.1.1. from Openssl is referred as depenency.

[build-dependencies.openssl-src]
version = "111"
optional = true

While in openssl-src it is stated that main is targeting main which builds OpenSSL 3.0.
As this is optional I try to link to a static OpenSsl 3.0 library I don't believe it is related to my problem, but it might be worth to adjust.

Got it working,root cause was me setting the environment variables wrong. The compiler message referring to the -L flag confused me, but now I got it right.
Here my settings (for Linux), in case anybody has similar issues.

#  .bashrc
export OPENSSL_LIBS=ssl:crypto 
export OPENSSL_STATIC=1
export OPENSSL_INCLUDE_DIR=/<PATH_TO_STATIC LIBRARY_FOR_OPENSSL>/openssl-3.0.7  #  <-- not sure if needed for static linkage
export OPENSSL_LIB_DIR=/<PATH_TO_STATIC LIBRARY_FOR_OPENSSL/openssl-3.0.7

Thx
