asciidoc/python issue: "code for hash sha224 was not found"

[njbartlett]

Using asciidoc and python (both brewed) several errors are reported about unsupported hash types.

Apparently the python hashlib functionality has a dependency on openssl; this is also installed from Homebrew on my system, though I didn't understand the message about openssl not being symlinked into /usr/local.

Full error trace is as follows:

What exactly are you doing to trigger this error? We need repro steps, and brew --config and brew doctor wouldn't hurt either.

[njbartlett]

Apologies for slow response, I hope you can reopen given the information below.

To reproduce the issue, the following single command is sufficient: python -c "import hashlib". This will produce the error trace shown above.

Output of brew --config is as follow:

Output of brew doctor:

Does this reproduce for anyone on 10.8?

[MikeMcQuaid]

@samueljohn Brewed Python alert :D

[samueljohn]

Oh alert? It midnight here. Can one reproduce?
Does brew reinstall python fix this for you? Perhaps you installed --with-brewed-openssl and then unlinked or removed. I can say more tomorrow.

[adamv]

Heh, not an actual alert.

[MikeMcQuaid]

@samueljohn Sorry, yes,not an alert. I was more saying "you may have an idea of what is going on here and/or be able to reproduce it".

[samueljohn]

@adamv @MikeMcQuaid it's alright - at first I thought I broke our python or something.

@njbartlett
I just tested it and - as I suspected - I can only reproduce if:

• brew install python --with-brewed-openssl
• brew uninstall openssl

So brew missing and brew doctor should diagnose this here. It could also be the case that there is an openssl from elsewhere that python picked up or something.

To fix this, either brew install python or if you want the brewed openssl instead of the one that comes with OS X:
brew reinstall openssl, brew reinstall python --with-brewed-openssl.

I assume this is fix and close this. If I am wrong, please provide us the brew doctor output and let us know.
Have a nice weekend all :-)
