[okl4-developer] Using Gcc 4.1/4.3

[G S Madhusudan]

1. Apps will be native and Linux based. But down the road, I am hoping we
get rid of Linux (the goal of the project is in fact to find an 
alternative to Linux !)

2. I am trying to build a standard L4 env for network appliances and the 
idea is to get 3rd party
modules to be dynamically installable. As you can see, having a std tool 
chain makes this
a little easier, otherwise we are bound to see issues with lib 
incompatibility. I personally
do not have a problem with a custom toolchain, having used cross 
complier tools
for the past 25 years ! But I want the env to be used for teaching and 
maybe some research and
custom tools do make adoption more difficult.

But to repeat my question, is updating the complier that difficult ? I 
have not done any analysis , so I do not have a clue.
I plan to create a GUI driven build env for L4 to enable fine grain 
customization and to be able to build
to specific resource constraints. As part of this effort, I can take a 
stab at updating the compiler, if the
effort is not significant.
