[arm-gnu] undefined reference to _init

[Brad Badke]

Well, I installed your 30 day trial. I would have thought I could just redirect my makefile and ld file to the new compiler and linker and all would work just fine, but I get two linker errors:

undefined reference to `__cxa_pure_virtual'

and 

undefined reference to `abort'

I can make my own abort easy enough but the `__cxa_pure_virtual' is a problem.

You're application is the best benchmark.

Go get a 30-day evaluation of the tools and try it out?
