# rust-openssl

[](https://travis-ci.org/sfackler/rust-openssl)
|
|
|
|
[Documentation](https://sfackler.github.io/rust-openssl/doc/v0.7.4/openssl).
|
|
|
|
## Building
|
|
|
|
rust-openssl depends on both the OpenSSL runtime libraries and headers.
|
|
|
|
### Linux
|
|
|
|
On Linux, you can install OpenSSL via your package manager. The headers are
|
|
sometimes provided in a separate package than the runtime libraries - look for
|
|
something like `openssl-devel` or `libssl-dev`.
|
|
|
|
```bash
|
|
# On Ubuntu
|
|
sudo apt-get install libssl-dev
|
|
# On Arch Linux
|
|
sudo pacman -S openssl
|
|
```
|
|
|
|
### OSX
|
|
|
|
OpenSSL 0.9.8 is preinstalled on OSX. Some features are only available when
|
|
linking against OpenSSL 1.0.0 or greater; see below on how to point
|
|
rust-openssl to a separate installation. OSX releases starting at 10.11, "El
|
|
Capitan", no longer include OpenSSL headers which will prevent the `openssl`
|
|
crate from compiling.
|
|
|
|
For OSX 10.11 you can use brew to install OpenSSL and then set the environment variables
|
|
as described below.
|
|
```bash
|
|
brew install openssl
|
|
export OPENSSL_INCLUDE_DIR=/usr/local/opt/openssl/include
|
|
export OPENSSL_LIB_DIR=/usr/local/opt/openssl/lib
|
|
```
|
|
|
|
### Windows
|
|
|
|
On Windows, consider building with [mingw-w64](http://mingw-w64.org/).
|
|
Build script will try to find mingw in `PATH` environment variable to provide
|
|
Cargo with location where openssl libs from mingw-w64 package may be found.
|
|
If you followed guide [Building on Windows](https://github.com/rust-lang/rust#building-on-windows)
|
|
from rust repo, then you should have [MSYS2](http://msys2.github.io/) with
|
|
`mingw-w64-openssl` installed as part of `mingw-w64-x86_64-toolchain`
|
|
(or `mingw-w64-i686-toolchain`) package.
|
|
|
|
Alternatively, install OpenSSL from [here][1]. Cargo will not be able to find OpenSSL if it's
|
|
installed to the default location. You can either copy the `include/openssl`
|
|
directory, `libssl32.dll`, and `libeay32.dll` to locations that Cargo can find
|
|
or pass the location to Cargo via environment variables:
|
|
|
|
```bash
|
|
env OPENSSL_LIB_DIR=C:/OpenSSL-Win64 OPENSSL_INCLUDE_DIR=C:/OpenSSL-Win64/include cargo build
|
|
```
|
|
|
|
### Manual configuration
|
|
|
|
rust-openssl's build script will by default attempt to locate OpenSSL via
|
|
pkg-config. This will not work in some situations, for example, on systems that
|
|
don't have pkg-config, when cross compiling, or when using a copy of OpenSSL
|
|
other than the normal system install.
|
|
|
|
The build script can be configured via environment variables:
|
|
* `OPENSSL_LIB_DIR` - If specified, a directory that will be used to find
|
|
OpenSSL runtime libraries.
|
|
* `OPENSSL_INCLUDE_DIR` - If specified, a directory that will be used to find
|
|
OpenSSL headers.
|
|
* `OPENSSL_STATIC` - If specified, OpenSSL libraries will be statically rather
|
|
than dynamically linked.
|
|
|
|
If either `OPENSSL_LIB_DIR` or `OPENSSL_INCLUDE_DIR` are specified, then the
|
|
build script will skip the pkg-config step.
