### Why aren't you using Alpine Linux, OpenBSD, or HardenedBSD?
Alpine Linux is not supported out-of-the-box by any major cloud provider. We are interested in supporting Free-, Open-, and HardenedBSD. Follow along or contribute to our BSD support in [this issue](https://github.com/trailofbits/algo/issues/35).
## Troubleshooting
### Error: "You have not agreed to the Xcode license agreements"
On macOS, did you try to install the dependencies with pip and encounter the following error?
```
Downloading cffi-1.9.1.tar.gz (407kB): 407kB downloaded
Running setup.py (path:/private/tmp/pip_build_root/cffi/setup.py) egg_info for package cffi
You have not agreed to the Xcode license agreements, please run 'xcodebuild -license' (for user-level acceptance) or 'sudo xcodebuild -license' (for system-wide acceptance) from within a Terminal window to review and agree to the Xcode license agreements.
No working compiler found, or bogus compiler options
passed to the compiler from Python's distutils module.
See the error messages above.
(If they are about -mno-fused-madd and you are on OS/X 10.8,
see http://stackoverflow.com/questions/22313407/ .)
----------------------------------------
Cleaning up...
Command python setup.py egg_info failed with error code 1 in /private/tmp/pip_build_root/cffi
Storing debug log for failure in /Users/algore/Library/Logs/pip.log
```
The Xcode compiler is installed but requires you to accept its license agreement prior to using it. Run `xcodebuild -license` to agree and then retry installing the dependencies.
### Error: "fatal error: 'openssl/opensslv.h' file not found"
On macOS, did you try to install pycrypto and encounter the following error?
```
build/temp.macosx-10.12-intel-2.7/_openssl.c:434:10: fatal error: 'openssl/opensslv.h' file not found
#include <openssl/opensslv.h>
^
1 error generated.
error: command 'cc' failed with exit status 1
----------------------------------------
Cleaning up...
Command /usr/bin/python -c "import setuptools, tokenize;__file__='/private/tmp/pip_build_root/cryptography/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-sREEE5-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /private/tmp/pip_build_root/cryptography
Storing debug log for failure in /Users/algore/Library/Logs/pip.log
```
You are running an old version of `pip` that cannot build the `pycrypto` dependency. Upgrade to a new version of `pip` by running `sudo pip install -U pip`.
