[augeas-devel] gnulib update for AIX support

[James Conner]

Hi Folks (particularly David & Matthew)

Thanks for the latest set of hints/pointers - I was indeed missing Flex 
from my AIX box (although I had put bison on there already). After I 
added a suitable version of Flex on there, autogen completes 
successfully. However, I am now onto a new problem during linking. It 
tells me "ERROR: Undefined symbol: .aug_span" when it tries to link 
augtool together. (I've attached a complete build log from start to 
finish in the hope that someone can spot what I'm doing wrong now).

I am not sure why it is giving me an undefined symbol - The exact same 
code compiles and links perfectly on my Ubuntu box. For completeness, I 
also tried the alternative route of running autogen.sh and 'make dist' 
on a different box, then doing the compile on AIX - It gives exactly the 
same results with an undefined symbol for aug_span during linking.

Any pointers?

Cheers,

Jim
