julia.rb: Undefined method "+" in ruby script.

[samueljohn]

With the latest changes in homebrew (superenv), the ENV['CPPFLAGS'] are now nil.
(UPDATE: unless you specify --env=std.)

Error: undefined method `+' for nil:NilClass

Perhaps, now with superenv, we can remove the CFLAGS/CPPFLAGS hack?

[samueljohn]

Hmm, seems that CPPFLAGS are still needed, right?
Using --env=std circumvents the nil thing from above. But even then (just a bit further) julia build fails for me.
Here is my current log.

Julia's build system is unfortunately not rock-stable...

I've pushed a fix that works for me; see if it magically fixes up those errors you're having.

Really, our problems are two-fold; we need to clean up Julia's build system to respect CPPFLAGS, and then we need to use more superenv-style thinking to manually add env's we need for julia to build properly. superenv screws around with things like julia's pre-build step where it finds the suite-sparse libraries by searching on paths specified by -L in LDFLAGS, etc.....

[samueljohn]

You are absolutely right about that. I wish julia would just build the normal way, i.e. without copying other libs around. For example, I favor making suite-sparse dynamic in the suite-sparse formula than julia doing this in its own little directory. Sure superenv breakes those things.
At least --env=std will not go away and soon there will be a way to declare the std-env from within the formula itself.

For now I am on vacation for a week. Testing has to wait. cu!

[staticfloat]

What a coincidence, I'm off to vacation in Europe for two weeks starting today. Enjoy your vacation time!

[samueljohn]

Thanks. With --env=std it's working (again).
