While trying to build a toolchain with ct-ng 1.5.0,
arm-unknown-linux-uclibcgnueabi target,
I get the following error:
[INFO ] Installing C library headers
[EXTRA] Copying sources to build dir
[EXTRA] Applying configuration
[EXTRA] Building headers
[EXTRA] Installing headers
[ERROR] extra/scripts/unifdef.c:209: error: conflicting types for 'getline'
[ERROR] make[2]: *** [extra/scripts/unifdef] Error 1
[ERROR] Build failed in step 'Installing C library headers'
The following patch solves the problem.
(It's a backport of this uClibc commit:
http://git.uclibc.org/uClibc/commit/?id=49e81cada73616864b9b31df0aeb6961c30f5a6e
)
[--SNIP from another mail--]
AFAIK this is a problem since glibc 2.10.

Add config option to build wtarget code with THUMB interworking.
This is used to build the C library as well as all other code
that runs on the target.
|
|
|
|
The ABI option can not be set if EABI was selected,
so no need to check for it.
|
|
Some ARM cores do not have an MMU (eg. Cortex-Mx and Cortex-Rx series).
Thus, allow the user to configure out the MMU for ARM.
|
|
The newlib "team" rolls new releases about once a year (december).
This is quite a long time between releases, in case code was fixed.
So, allow user to use a CVS snapshot to benefit early from fixes
and enhancements to newlib.
|
|
Some projects' module (eg. newlib) are checked-out into a sudirectory
rather than into their own directory. Handle this case in the CT_GetCVS
function.

C library config options should be prefixed with 'LIBC_'.
|
|
build step:
- ./configure
- remove glibc-specific options
- pass the target CFLAGS in the correct variable
- make:
- build in //
finish step:
- print proper message in finish step

newlib handles the build/host/target a bit differently as one would expect:
build : not used
host : the nachine that builds newlib
target : the machine on which newlib will run
|
|
|
|
|
|
This yields a cleaner .config file that is easier to read.

When a required tool is specified with --with-foo, store the variable
in the list.
|
|
|

It's been a while that configure does not recognise --with-contrib.
Applying contibutions is to be done manually, using patch.

Bizarely enough, binutils-2.18 fails to build when CONFIG_SHELL is set
to /bin/bash (although it has code to recognise bash and act accordingly).
Waht is really strange is that it does build when CONFIG_SHELL is set
to /bin/sh, *although* /bin/sh is a symlink to /bin/bash. WTF?!?!

Split the has_or_abort function in two:
- one that checks if the tool if found,
- one that calls the above check, and aborts if not found
The rational behind this is to be able to check for a tool
and if not found, fallback to using our bundled version,
should the need arise (and I get time).

glibc snapshots have not been updated for about the
past 5 months. Consider them to be deprecated, now.

ncurses is built solely for the sake of building a native gdb.
The user should not rely on this library to build his/her userland,
but should rather build his/her own. So we remove it from the
sysroot after we successfully build the native gdb.
|
|
Update this sample, now it seems to correctly build again.

Build eglibc with -O2 as a fix/workaround to building
seemingly-native toolchains (see docs/overview.txt).

The option to retrieve snapshots is already handled by
the generic 'specific date' and 'use latest' entries.
No need for a special case, as there's no code for it.
|
|
Upgrading all samples is too much a hassle.
Stick with those few for now.
|
|
Use the generic arm-cortex_a8-linux-gnueabi sample instead.
