RE: [Ltib] Can't get: linux-2.6.16-mx31-sdio.patch at ./ltibline599.

[Sesto, Vin]

Hi Steve

Thanks for your reply. Ltib is currently building and am hoping it
builds OK before I venture onto the next step ... which is to build a
native gcc supporting eabi/nptl version 4.1.1 

I guess I need a little more clarification as to your statement of the
gcc spec file in ltib will need some work to build a native gcc for arm
eabi targets. I am new to this so don't mind my trivial questions.

Could you please give me some hints as to how I should go about
achieving the native gcc 4.1.1 build versus the 3.4.3? I guess that's
been part of my issue all along.

Thanks.

Vin

Hi Vin,

Your approach is correct, once you have ltib installed you can normally
select the gcc package and it will build gcc for the target root file
system.  You don't need to put the cross compiler in your PATH as ltib
takes care of all this for you.

However the gcc spec file currently in ltib builds gcc-3.4.3, so if you
want a non eABI generic arm gcc then this should work for you, but if
you need an arm eABI toolchain then you need a later version of gcc.  In
summary the gcc spec file in ltib will need some work to build a native
gcc for amr eABI targets,

Best regards,

Steve
