[Insight-developers] linker won't build new library

[Luis Ibanez]

Hi Michael,

Thanks for pointing to the respective code.

I just tried it,... and it builds for me.

I built it with gcc 4.4, in Ubuntu 9.10.

Is it because you already solved the issue ?

This is the commit version:

   936fcfe2dad60fd3d9cb6f6ef21cc54ce437bae1

and it is  from the "testbranch".


I'm submitting an Experimental build
to the Dashboard now.


      Luis
