The reasons behind the Linux version? #17

Closed ilg-ul closed 12 years ago

James,

Can you help me understand the reasons behind maintaining the Makefile to run on Linux?

I recently installed the latest CodeSourcery IA32 GNU/Linux TAR (the advanced package) on a 64bit Ubuntu 11.10 and (at least apparently) had no problems.

Is there anything wrong with their distribution that you fixed?

It's fairly easy once it works on OS X. Also given that the build takes a while I have an 8 core Linux box that's quicker to iterate on than my Mac laptop for initial build testing.

Also as mentioned, I build newlib with a few optimizations geared towards code size, so I like having the same chain on both platforms.

Not really. It now matches their build settings even more closely aside from the newlib flags being a little different. I had to just adjust a few things to accommodate some changed build dependencies for gcc 4.6 and turning on LTO.

ah, ok, that's a good reason.

I build newlib with a few optimizations geared towards code size, so I like having the same chain on both platforms.

how complicated would be to add a switch to either apply these optimisations, or revert exactly to the settings used by CodeSourcery versions?
