[cfe-dev] Is __attribute(weak) supposed to fail?

[Kelly W]

Hey Eric,

There is no bug filed for this, that I could see. 

I did get libxml2 to compile without pthread support and 'make tests' worked
(though I am apparently missing some test xml files...but at least there
were no fatal errors and 'testapi' seemed fine excluding pthread tests).

So my question on '__attribute(weak)' still stands, but at least I could get
around it.

Thanks,
K.Wilson

Hunh. It shouldn't be too hard to support - is there a bug for it? If  
it's supported in some way (objc_gc? weird.) on darwin it should be  
easy to support on linux.
