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'.

This string will be interpreted as a directory component to be added
|
|
to the sysroot path, just before the actual sysroot directory.
|
|
|

In fact, the sysroot path is constructed as:
|
|
${CT_PREFIX_DIR}/${CT_TARGET}/${CT_SYSROOT_DIR_PREFIX}/sys-root

Say 'y' here, unless you don't want shared libraries.
|

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

Vendor part of the target tuple.
|
|
|
|
A tuple 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.
|
|
Use neither dash nor space, as it breaks things.
|

Keep the default (unkown) if you don't know better.

Normaly, you'd call your toolchain components (especially gcc) by
|
|
prefixing the target tuple followed by a dash and the component name
|
|
(eg. armeb-unknown-linux-uclibc-gcc).
|
|
|
|
You can enter here a sed expression to be applied to ${CT_TARGET} to
|
|
create an alias for your toolchain.
|
|
|
|
For example, "s/${CT_TARGET_VENDOR}/foobar/" (without the double quotes)
|
|
will create the armeb-foobar-linux-uclibc alias to the above-mentioned
|
|
toolchain.
|
|
|
|
You shouldn't need to enter anything here, unless you plan to manually
|
|
call the tools (autotools-based ./configure will use the standard name).
