error: failed to run custom build command for `openssl-sys v0.9.13`
run pkg_config fail: "Failed to run `\"pkg-config\" \"--libs\" \"--cflags\" \"openssl\"`: No such file or directory (os error 2)"
Problem encountered on WSL (Ubuntu on windows).
Fixed by installing pkg-config
Prior to this commit in 43c951f743 the
ability to pass OPENSSL_LIBS was removed from the build.rs of
openssl-sys. This commit adds the ability to pass custom names for the
OPENSSL_LIBS back in. This is useful for when building openssl across
linux and windows with the same lib names (ssl:crypto) and the default
names provided by the build script are not valid.
The slproweb.com OpenSSL distribution does not contain root certificates, so they need to be downloaded and installed manually to avoid certificate warnings when making requests.
This commit is relatively major refactoring of the `openssl-sys` crate as well
as the `openssl` crate itself. The end goal here was to support OpenSSL 1.1.0,
and lots of other various tweaks happened along the way. The major new features
are:
* OpenSSL 1.1.0 is supported
* OpenSSL 0.9.8 is no longer supported (aka all OSX users by default)
* All FFI bindings are verified with the `ctest` crate (same way as the `libc`
crate)
* CI matrixes are vastly expanded to include 32/64 of all platforms, more
OpenSSL version coverage, as well as ARM coverage on Linux
* The `c_helpers` module is completely removed along with the `gcc` dependency.
* The `openssl-sys` build script was completely rewritten
* Now uses `OPENSSL_DIR` to find the installation, not include/lib env vars.
* Better error messages for mismatched versions.
* Better error messages for failing to find OpenSSL on a platform (more can be
done here)
* Probing of OpenSSL build-time configuration to inform the API of the `*-sys`
crate.
* Many Cargo features have been removed as they're now enabled by default.
As this is a breaking change to both the `openssl` and `openssl-sys` crates this
will necessitate a major version bump of both. There's still a few more API
questions remaining but let's hash that out on a PR!
Closes#452
