Failed to require on Ubuntu 12.04LTS

With node v0.12.0 and npm 2.5.1, npm install goes through fine:

\
> nodegit@0.3.3 install node_modules/nodegit
> node lifecycleScripts/install

[nodegit] Fetching binary from S3.
[nodegit] Completed installation successfully.

> nodegit@0.3.3 postinstall node_modules/nodegit

But then

~$ node

After installing from the repository, I got cc1plus: error: unrecognized command line option ‘-std=c++11’, which lead me to upgrade to gcc 4.8. Nodegit now works fine.

Did you recompile nodegit using gcc or did you just upgrade and then it worked?

I recompiled using gcc

Yeah, IIRC GCC 4.6 and below don't support -std=c++11

I'll make sure theres a note in the readme.

I think we have a note for that already. The problem here was originally libc or libstdc++ being out-of-date though. We need to document that in a way that isn't super confusing and easy to check.

λ ldd ~/git/nodegit/nodegit/build/Release/nodegit.node

Edit: accuracy with words

Hrm, it seems like the build instructions are gone entirely, at least from the readme O.o

They exist in the install from source guide: http://www.nodegit.org/guides/install/from-source/
