Keil vs GCC for ARM7?

Question

How does Keil compare to GCC for ARM7 development? I'm in the process of choosing hw consultants for a medium size project and some use keil and some use gcc. I'd like to know the gotchas involved in going with either option...

Answer 1

There is very little difference between the two from a coding/development standpoint. The only thing I think you should consider is not specific to these compiler. Maintenance:

• Will you be able to maintain the software if you do not have access to the Keil compiler or will it be a minor cost?
• Also what debughardware/JTAG is supported and what will the cost be if you need to get some?
  
• What will the cost be if you have to move from one compiler to other compiler due to having to switch developers later?
  

Unless you are very cost sensitive I think the real question is who will do the best job since the compiler will be a minor problem.
