Use the 'shinny new' sysroot feature of gcc: libraries split between
|
|
prefix/target/sys-root/lib and prefix/target/sys-root/usr/lib

You definitely want to say 'Y' here. Yes you do. I know you do. Say 'Y'.

Say 'y' here, unless you don't want shared libraries.
|
|
|
|
You might not want shared librries if you're building for a target that
|
|
don't support it (maybe some nommu targets, for example, or bare metal).

help
|
|
Enable the so-called 'multilib' support.
|
|
|
|
With the same toolchain, and on some architectures, you will be able to
|
|
build big and little endian binaries, soft- and hard-float, etc...
|
|
|
|
See the gcc configure manual at http://gcc.gnu.org/install/configure.html
|
|
to see what multilib your target supports.
|
|
|
|
It's preferable for now to build two (or more) toolchains, one for each
|
|
configuration you need to support (eg. one for thumb and one for ARM,
|
|
etc...). You can use the vendor string to diferentiate those toolchains.

config TARGET_VENDOR

help
|
|
Vendor part of the machine triplet.
|
|
|
|
A triplet is of the form arch-vendor-kernel-system.
|
|
You can set the second part, vendor, to whatever you see fit.
|
|
Use a single word, or use underscores "_" to separate words.
|
|
|
|
Keep the default (unkown) if you don't know better.

config TARGET_ALIAS

|

help
|
|
Normaly, you'd call your toolchain component (especially gcc) by
|
|
prefixing the target triplet followed by a dash and the component name
|
|
(eg. armeb-unknown-linux-uclibc-gcc).
|
|
|
|
You can enter a shortcut here. This string will be used to create
|
|
symbolic links to the toolchain tools (eg. if you enter "foo-bar" here,
|
|
then gcc for your toolchain will also be available as "foo-bar-gcc" along
|
|
with the original name).
|
|
|
|
You shouldn't need to enter anything here, unless you plan to manually
|
|
call the tools (autotools-based ./configure will use the standard name).

The native C compiler.

You can set this to an alternative compiler if you have more than one
|
|
installed (eg. gcc is gcc-4.1.1 and you want to use gcc-3.4.6).
|
|
|
|
You can leave this empty as well, in which case gcc will be used.
