Build fails on Heroku

[syu-id]

Glad to hear that libsass-python is again compatible with older GCC versions.
However when I try to deploy my app to Heroku with libsass-python 0.6.2, it still fails.

I was running into this same issue and discovered 2 things:

1. libsass==0.5.1 compiled fine
2. In November Heroku released the new "cedar-14" stack as default which is built off Ubuntu 14, compared to 10 of the original. Cedar-14 comes along with a newer gcc / g++ (4.8).

Upgrading to cedar-14 resolved this compilation issue for me.

Even though the original cedar stack should be compatible (g++ 4.4), it doesn't seem happy with the exact setup for whatever reason.

The upgrade to cedar-14 was pain free for me.

Updating to cedar-14 also fixed this bug for me.

On CentOS 6.6, build with version >= 0.6.0 fails while 0.5.1 works fine as kcolton mentioned above. You can find the error messages here.

Unfortunately you'll need a newer version of gcc, this is documented here: https://github.com/dahlia/libsass-python#install and here: https://github.com/sass/libsass#readme

There's a PR in libsass to work with GCC 4.4. If anyone has the time to review it/help them: sass/libsass#1623
